Key clinical point: Signatures of circulating microRNA in patients with psoriatic arthritis (PsA) and patients with psoriasis were significantly different from those in control individuals, with some even being differentially regulated between PsA and psoriasis.

Major finding: Overall, 9 microRNA best differentiated patients with PsA and psoriasis from control individuals (area under the curve [AUC] ≥0.70; all P < .05) and 4 microRNA best differentiated patients with PsA from patients with psoriasis (all P < .05). A combination of 4 microRNA (miR-19b-3p, miR-21-5p, miR-92a-3p, and let-7b-5p) vs miR-92a-3p alone could better differentiate between patients with PsA and psoriasis (AUC 0.92 vs 0.82).

Study details: This cross-sectional study included 51 patients with PsA, 40 patients with psoriasis, and 50 control individuals.

Disclosures: This study did not receive any specific funding. Two authors declared being employees or shareholders of TAmiRNA GmbH or holding intellectual property for the diagnostic use of microRNA in bone diseases.

Key clinical point: The crude mortality rate increased by two-fold in patients with psoriatic arthritis (PsA) during the COVID-19 pandemic compared with the pre-pandemic era, with pulmonary reasons being the major risk factors for mortality.

Major finding: Although standard mortality rates were similar between patients with PsA and the general population during the pre-pandemic period (0.95; 95% CI 0.61-1.49), the crude mortality rate, which was 5.07 before the pandemic, increased by 2.12-fold during the pandemic in the PsA population. Interestingly, deaths due to pulmonary reasons increased from 6% during the pre-pandemic era to 66% during the pandemic.

Study details: Findings are from an international multicenter registry study including 1216 patients with PsA who were followed up for 7500 patient-years.

Disclosures: This study did not report the source of funding. Some authors declared receiving honoraria or research grants from several sources.

Key clinical point: All multiple manifestations of psoriatic arthritis (PsA) negatively affect quality of life (QoL), with dactylitis, peripheral joint disease, and psoriasis impairing functional status, whereas joint, skin, and periarticular symptoms independently impair work productivity.

Major finding: Presence vs absence of enthesitis, dactylitis, inflammatory back pain, and peripheral joint involvement was associated with worse QoL and self-rated health (all P < .05), whereas increasing number of affected joints and greater body surface area involvement significantly correlated with poorer functional state and greater work productivity impairment (all P < .05).

Study details: Findings are from a cross-sectional observational study including 2222 patients with physician-confirmed diagnosis of PsA.

Key clinical point:  Patients with psoriasis and concomitant psoriatic arthritis (PsA) had a greater comorbidity burden compared with those with psoriasis alone, which negatively impacted treatment persistence.

Major finding: Among patients receiving ustekinumab, those with concomitant PsA vs psoriasis alone had higher comorbidity burden, including diabetes (odds ratio [OR] 1.52; 95% CI 1.16-1.97), hypertension (OR 1.55; 95% CI 1.27-1.89), and obesity (OR 1.33; 95% CI 1.1-1.61), and a shorter time to ustekinumab discontinuation (hazard ratio 1.98; P < .0001).

Study details: This was a retrospective study including 9057 patients with plaque psoriasis alone or with concomitant PsA who received either ustekinumab or conventional systemic disease-modifying antirheumatic drugs.

Introduction

The COVID-19 pandemic has changed the healthcare system in a multitude of ways, affecting healthcare capacity, treatment of other illnesses, and wellness as well as professional retention of healthcare workers.^1-3 During the peak of the COVID-19 pandemic, healthcare capacity was tested and resources were used up quickly.¹ As the pandemic has progressed, healthcare systems have had to decide how to proceed with lessons learned, reassessing the environment of care delivery, healthcare supply chains, workforce structures, communication systems, and scientific collaboration as well as policy frameworks in healthcare.⁴ 

There have been both immediate effects and long-term consequences of the delay in care for other conditions.^2,5 One stark example of this is in cancer care, where screening and procedures were postponed or canceled due to the pandemic with a resulting predicted 2% increase in cancer mortality in the next 10 years.² The care of heart disease, chronic illnesses, and other viruses has also been similarly negatively impacted by the COVID-19 pandemic due to similar delays in diagnosis and treatment.^5-7 

The impact on healthcare workers has also been profound.³ Occupational stress from the pandemic has correlated with increased depression and posttraumatic stress disorder (PTSD) among other mental health diseases in healthcare workers.³ In a survey of neurosurgery residents, 26.1% of physicians reported feeling burnt out, and 65.8% were worried that they would not be able to reach surgical milestones.^8,9 Among respiratory therapists, a hard hit group during this time, 79% reported burnout.¹⁰ Additionally, more healthcare workers left the field during the pandemic, with 15 million lost jobs. Future recovery of jobs looks bleak in some settings, like long-term care and among assistants and aides.¹¹ Overall, the long-term outcomes of these resource, disease, and mental health disruptions need to be assessed and solutions created to maintain a quality and effective healthcare system, with ample resources and measures to account for disease increases and address the impact on providers. 

Healthcare Capacity and Resources 

With COVID-19 affecting over 100 million in the United States as of March 1, 2023, the impact on healthcare resources since the start of the pandemic has been immense.¹² With 5% to 38% of hospitalized patients being admitted to the intensive care unit (ICU) and 75% to 88% of those patients requiring mechanical ventilation, a huge strain was placed on resources during and after the pandemic.¹ 

The question of balancing resources for other hospital needs while tending to patients with COVID-19 has been an ongoing discussion at many levels.¹ One core resource concern is the lack of staff. In a survey of 77 different countries, including physicians (41%), nurses (40%), respiratory therapists (11%), and advanced practice providers (8%), 15% reported insufficient intensivists and 32% reported insufficient ICU nursing staff during March and April of 2020.¹ A lack of hospital and care space that led to reallocation of limited-care acute care space was a concern. Thirteen percent reported a shortage of hospital ICU beds, while others reported the conversion of postoperative recovery rooms (20%) and operating rooms (12%) for patients with COVID-19.¹ 

Along with staff and care space concerns, hospital survey respondents reported that healthcare equipment was also challenged. Access to COVID-19 testing was one concern, with only 35% of respondents reporting availability for all patients at the beginning of the pandemic, and 56% reporting availability for only select patients based on symptom severity.¹ Access to personal protective equipment (PPE) was also affected, with PPE always available according to 83% to 95% of respondents but just 35% having access to N95 masks.¹ Additionally, 26% reported that there were no respirators in their hospital, and 11% reported limited ventilators.¹ 

Although resource depletion is a problem, studies have looked at public health measures that helped to mitigate this issue. With proper public health planning and implementation, such as physical distancing, aggressive testing, contact tracing, and increased hospital capacity, by freeing up existing resources or adding additional support, public health modeling showed that resources may be able to withstand the increase.¹³ Development of reallocation models at local, state, national, and international levels is an important step to be able to deal with future public health crises.¹⁴

The long-term impact from the pandemic includes disruption in the physical environment of healthcare, production, supply chain, staff structure, and workforce alterations.⁴ For example, the physical shape of healthcare facilities is changing to accommodate increasing volumes and decrease the risk of spreading disease.⁴ To accommodate the burden on staffing structure and workforce alteration, telehealth gained a prominent role.⁴ All in all, the pandemic has changed the healthcare system; however, institutions, organizations, and policy makers need to evaluate which measures were impactful and should be considered for long-term inclusion in healthcare practice. 

Impact on Other Diseases: Cancer, Heart Disease, Chronic Illnesses, and Other Viruses 

The treatment of other new and existing conditions has also been affected by the pandemic. Cancer, especially, is a disease of concern. Elective surgeries and screening were halted or altered during the pandemic, which is modeled to lead to higher cancer mortality in years to come.² The most affected cancers were breast, lung, and colorectal cancer.² A study of colorectal cancer screening showed that colonoscopies were delayed due to COVID-19 and that gastroenterology visits declined by 49% to 61%.¹⁵ This will likely lead to delayed cancer diagnoses and possible increases in mortality.¹⁵ Breast cancer screening was also delayed and many patients continued to avoid it for various reasons such as fears of contracting COVID-19 infection in healthcare facilities, and the economic effects of the pandemic such as job loss and healthcare coverage loss.¹⁶ These delays will result in an estimated potential 0.52% overall increase in breast cancer deaths by 2030.¹⁷

A study of 368 patients from Spain showed a 56.5% decrease in hospital admissions, usually related to heart attacks, in March and April of 2020, compared to January and February 2020.^18,19 For other chronic illnesses, the pandemic resulted in decreased preventative care and management.²⁰ The care of other infections similarly suffered. The World Health Organization announced that the number of patients receiving treatment for tuberculosis (TB) dropped by 1 million, setting the disease mitigation back considerably.²⁰ An estimated 500,000 more people died in 2020 from TB.²¹ The drastic shift in focus to COVID-19 care during this period will continue to have a profound impact on other diseases like these for many years post-pandemic.

Provider Experience and Mental Health Outcomes 

The impact on provider experiences and mental health has been immense. One study of 510 healthcare providers (HCPs) and first responders found that occupational stress from the pandemic correlated with psychiatric symptoms, including depression, PTSD, insomnia, and generalized anxiety.³ Occupational stress also correlated with one’s likelihood to leave the medical field and trouble doing work they had once loved.³ Half of the healthcare workers surveyed indicated a decreased likelihood of staying in their current profession after the pandemic.³ 

Other studies have also looked at specific subspecialties and impact on trainees during the pandemic. In neurosurgery, for example, resident burnout is high, at 26.1%.⁹ Additionally, the lack of surgeries in the pandemic made 65.8% of neurosurgery residents anxious about meeting career milestones.⁹ Respiratory therapists, a highly impacted group, also experienced burnout, reporting higher levels in those who worked more in the ICU. Another study identified several themes in the concerns reported by healthcare workers during the pandemic era including “changes in personal life and enhanced negative affect,” “gaining experience, normalization, and adaptation to the pandemic,” and “mental health considerations.”²² 

Some studies have investigated ways to mitigate this dissatisfaction with the healthcare field post-pandemic. Intrapreneurship, reverse mentoring, and democratized learning all had a reported positive impact on employee experience and retention during this time.²³ Intrapreneurship describes entrepreneurship within an existing organization, while reverse mentoring and democratized learning refer to newer employees teaching older employees and communicative learning on a breadth of topics. Other studies have examined the necessity of having mental health resources available, and that these resources need to be multi-stage and individualistic as well as specific to certain stressors HCPs faced during the pandemic.²² 

Conclusion and Future Directions

The COVID-19 pandemic had stark effects on the healthcare system, impacting resources and capacity, care of other diseases, and provider mental health and experiences.^1-3 After the chaos of the pandemic, many questions remain. What needs to be done now by health systems and HCPs? How can we learn from the challenges and the effects on capacity to change the healthcare workflow in times of crisis and in the present? How do we mitigate the impact of the pandemic on diagnosis and management of diseases? And how do we continue to provide healthcare workers with proper mental health and professional resources now, not just in times of stress, and encourage the future generation to pursue careers in healthcare? 

These are all the questions the pandemic has left us with, and more studies and initiatives are needed to investigate solutions to these issues. The COVID-19 pandemic left behind valuable lessons and changed the healthcare system, disease management, and staffing for many. Now is the time to pick up the pieces and strategize on how to make our existing system more effective for workers and patients post pandemic. 

Introduction

The COVID-19 pandemic has changed the healthcare system in a multitude of ways, affecting healthcare capacity, treatment of other illnesses, and wellness as well as professional retention of healthcare workers.^1-3 During the peak of the COVID-19 pandemic, healthcare capacity was tested and resources were used up quickly.¹ As the pandemic has progressed, healthcare systems have had to decide how to proceed with lessons learned, reassessing the environment of care delivery, healthcare supply chains, workforce structures, communication systems, and scientific collaboration as well as policy frameworks in healthcare.⁴ 

There have been both immediate effects and long-term consequences of the delay in care for other conditions.^2,5 One stark example of this is in cancer care, where screening and procedures were postponed or canceled due to the pandemic with a resulting predicted 2% increase in cancer mortality in the next 10 years.² The care of heart disease, chronic illnesses, and other viruses has also been similarly negatively impacted by the COVID-19 pandemic due to similar delays in diagnosis and treatment.^5-7 

The impact on healthcare workers has also been profound.³ Occupational stress from the pandemic has correlated with increased depression and posttraumatic stress disorder (PTSD) among other mental health diseases in healthcare workers.³ In a survey of neurosurgery residents, 26.1% of physicians reported feeling burnt out, and 65.8% were worried that they would not be able to reach surgical milestones.^8,9 Among respiratory therapists, a hard hit group during this time, 79% reported burnout.¹⁰ Additionally, more healthcare workers left the field during the pandemic, with 15 million lost jobs. Future recovery of jobs looks bleak in some settings, like long-term care and among assistants and aides.¹¹ Overall, the long-term outcomes of these resource, disease, and mental health disruptions need to be assessed and solutions created to maintain a quality and effective healthcare system, with ample resources and measures to account for disease increases and address the impact on providers. 

Healthcare Capacity and Resources 

With COVID-19 affecting over 100 million in the United States as of March 1, 2023, the impact on healthcare resources since the start of the pandemic has been immense.¹² With 5% to 38% of hospitalized patients being admitted to the intensive care unit (ICU) and 75% to 88% of those patients requiring mechanical ventilation, a huge strain was placed on resources during and after the pandemic.¹ 

The question of balancing resources for other hospital needs while tending to patients with COVID-19 has been an ongoing discussion at many levels.¹ One core resource concern is the lack of staff. In a survey of 77 different countries, including physicians (41%), nurses (40%), respiratory therapists (11%), and advanced practice providers (8%), 15% reported insufficient intensivists and 32% reported insufficient ICU nursing staff during March and April of 2020.¹ A lack of hospital and care space that led to reallocation of limited-care acute care space was a concern. Thirteen percent reported a shortage of hospital ICU beds, while others reported the conversion of postoperative recovery rooms (20%) and operating rooms (12%) for patients with COVID-19.¹ 

Along with staff and care space concerns, hospital survey respondents reported that healthcare equipment was also challenged. Access to COVID-19 testing was one concern, with only 35% of respondents reporting availability for all patients at the beginning of the pandemic, and 56% reporting availability for only select patients based on symptom severity.¹ Access to personal protective equipment (PPE) was also affected, with PPE always available according to 83% to 95% of respondents but just 35% having access to N95 masks.¹ Additionally, 26% reported that there were no respirators in their hospital, and 11% reported limited ventilators.¹ 

Although resource depletion is a problem, studies have looked at public health measures that helped to mitigate this issue. With proper public health planning and implementation, such as physical distancing, aggressive testing, contact tracing, and increased hospital capacity, by freeing up existing resources or adding additional support, public health modeling showed that resources may be able to withstand the increase.¹³ Development of reallocation models at local, state, national, and international levels is an important step to be able to deal with future public health crises.¹⁴

The long-term impact from the pandemic includes disruption in the physical environment of healthcare, production, supply chain, staff structure, and workforce alterations.⁴ For example, the physical shape of healthcare facilities is changing to accommodate increasing volumes and decrease the risk of spreading disease.⁴ To accommodate the burden on staffing structure and workforce alteration, telehealth gained a prominent role.⁴ All in all, the pandemic has changed the healthcare system; however, institutions, organizations, and policy makers need to evaluate which measures were impactful and should be considered for long-term inclusion in healthcare practice. 

Impact on Other Diseases: Cancer, Heart Disease, Chronic Illnesses, and Other Viruses 

The treatment of other new and existing conditions has also been affected by the pandemic. Cancer, especially, is a disease of concern. Elective surgeries and screening were halted or altered during the pandemic, which is modeled to lead to higher cancer mortality in years to come.² The most affected cancers were breast, lung, and colorectal cancer.² A study of colorectal cancer screening showed that colonoscopies were delayed due to COVID-19 and that gastroenterology visits declined by 49% to 61%.¹⁵ This will likely lead to delayed cancer diagnoses and possible increases in mortality.¹⁵ Breast cancer screening was also delayed and many patients continued to avoid it for various reasons such as fears of contracting COVID-19 infection in healthcare facilities, and the economic effects of the pandemic such as job loss and healthcare coverage loss.¹⁶ These delays will result in an estimated potential 0.52% overall increase in breast cancer deaths by 2030.¹⁷

The Diagnosis: Superficial Angiomyxoma

Superficial angiomyxoma is a rare, benign, cutaneous tumor of a myxoid matrix and blood vessels that was first described in association with Carney complex.¹ Tumors may be solitary or multiple. A recent review of cases in the literature revealed a roughly equal distribution of superficial angiomyxomas in males and females occurring most frequently on the head and neck, extremities, and trunk or back. The peak incidence is between the fourth and fifth decades of life.² Superficial angiomyxomas can occur sporadically or in association with Carney complex, an autosomal-dominant condition with germline inactivating mutations in protein kinase A, PRKAR1A. Interestingly, sporadic cases of superficial angiomyxoma also have shown loss of PRKAR1A expression on immunohistochemistry (IHC).³

Common histologic mimics of superficial angiomyxoma include aggressive angiomyxoma and angiomyofibroblastoma.⁴ It is thought that these 3 distinct tumor entities may arise from a common pluripotent cell of origin located near connective tissue vasculature, which may contribute to the similarities observed between them.⁵ For example, aggressive angiomyxomas and angiomyofibroblastomas also demonstrate a similar myxoid background and vascular proliferation that can closely mimic superficial angiomyxomas clinically. However, the vessels of superficial angiomyxomas tend to be long and thin walled, while aggressive angiomyxomas are characterized by large and thick-walled vessels and angiomyofibroblastomas by abundant smaller vessels. Additionally, unlike superficial angiomyxomas, both aggressive angiomyxomas and angiomyofibroblastomas typically occur in the genital tract of young to middle-aged women.⁶

Histopathologic examination is imperative for differentiating between superficial angiomyxoma and more aggressive histologic mimics. Superficial angiomyxomas typically consist of a rich myxoid stroma, thin-walled or arborizing blood vessels, and spindled to stellate fibroblastlike cells (quiz image 2).³ Although not prominent in our case, superficial angiomyxomas also frequently present with stromal neutrophils and epithelial components, including keratinous cysts, basaloid buds, and strands of squamous epithelium.⁷ Minimal cellular atypia, mitotic activity, and nuclear pleomorphism often are seen, with IHC negative for desmin, estrogen receptor, and progesterone receptor; positive for CD34 and smooth muscle actin; and variable for S-100 and muscle-specific actin. Although IHC has limited utility in the diagnosis of superficial angiomyxomas, it may be useful to rule out other differential diagnoses.^2,3 Superficial angiomyxomas usually show fibroblastic stromal cells, proteoglycan matrix, and collagen fibers on electron microscopy.⁸ Importantly, histopathologic examination of aggressive angiomyxoma will comparatively present with more invasive, infiltrative, and less well-circumscribed tumors.⁹ Other differential diagnoses on histology may include neurofibroma, focal cutaneous mucinosis, spindle cell lipoma, and myxofibrosarcoma. Additional considerations include fibroepithelial polyp, nevus lipomatosis, angiomyxolipoma, and anetoderma.

An important differential diagnosis in the evaluation of superficial angiomyxoma is neurofibroma, a benign peripheral nerve sheath tumor that presents as a smooth, flesh-colored, and painless papule or nodule commonly associated with the buttonhole sign. Histopathology of neurofibroma features elongated spindle cells with comma-shaped or buckled wavy nuclei and variably sized collagen bundles described as “shredded carrots” (Figure 1).¹⁰ Occasional mast cells also can be seen. Immunohistochemistry targeting elements of peripheral nerve sheaths may assist in the diagnosis of neurofibromas, including positive S-100 and SOX10 in Schwann cells, epithelial membrane antigen in perineural cells, and fingerprint positivity for CD34 in fibroblasts.¹⁰

Cutaneous mucinoses encompass a diverse group of connective tissue disorders characterized by accumulation of mucin in the skin. Solitary focal cutaneous mucinoses (FCMs) are individual isolated lesions of mucin deposits that are unassociated with systemic conditions.¹¹ Conversely, multiple FCMs presenting with multiple cutaneous lesions also have been described in association with systemic diseases such as scleroderma, systemic lupus erythematosus, and thyroid disease.¹² Solitary FCM typically presents as an asymptomatic, flesh-colored papule or nodule on the extremities. It often arises in mid to late adulthood with a slightly increased frequency among males.¹² Histopathology of solitary FCM commonly demonstrates a dome-shaped pool of basophilic mucin in the upper dermis sparing involvement of the underlying subcutaneous tissue (Figure 2).¹³ Notably, FCM often lacks the vascularity as well as stromal neutrophils and epithelial elements that are seen in superficial angiomyxomas. Although hematoxylin and eosin stains can be sufficient for diagnosis of solitary FCM, additional stains for mucin such as Alcian blue, colloidal iron, or toluidine blue also may be considered to support the diagnosis.¹²

Spindle cell lipomas (SCLs) are rare, benign, subcutaneous, adipocytic tumors that arise on the upper back, posterior neck, or shoulders of middle-aged or elderly adult males.¹⁴ The clinical presentation often is an asymptomatic, well-circumscribed, mobile subcutaneous mass that is firmer than a common lipoma. Histologically, SCLs are characterized by mature adipocytes, spindle cells, and wire or ropelike collagen fibers in a myxoid background (Figure 3). The spindle cells usually are bland with a notable bipolar shape and blunted ends. Infiltrative growth patterns or mitotic figures are uncommon. Diagnosis can be supported by IHC, as SCLs stain diffusely positive for CD34 with loss of the retinoblastoma protein.⁷

Another important differential diagnosis to consider is myxofibrosarcoma, a rare and malignant myxoid cutaneous tumor. Clinically, it presents asymptomatically as an indolent, slow-growing nodule on the limbs and limb girdles.⁷ Histopathologic features demonstrate a multilobular tumor composed of a mixture of hypocellular and hypercellular regions with incomplete fibrous septae (Figure 4). The presence of curvilinear vasculature is characteristic. Multinucleated giant cells and cellular atypia with nuclear pleomorphism also can be seen. Although IHC findings generally are not specific, they can be used to rule out other potential diagnoses. Myxofibrosarcomas stain positive for vimentin and occasionally smooth muscle actin, muscle-specific actin, and CD34.⁷

Superficial angiomyxomas are benign; however, excision is recommended to distinguish between mimics. Local recurrence after excision is common in 30% to 40% of patients.¹⁵ Mohs micrographic surgery has been considered, especially if the following are present: tumor characteristics (eg, poorly circumscribed), location (eg, head and neck or other cosmetically or functionally sensitive areas), and likelihood of recurrence (high for superficial angiomyxomas). 16 This case otherwise highlights a rare example of superficial angiomyxomas involving the buttocks.

A recent review of cases in the literature revealed a roughly equal distribution of superficial angiomyxomas in males and females occurring most frequently on the head and neck, extremities, and trunk or back. The peak incidence is between the fourth and fifth decades of life.² Superficial angiomyxomas can occur sporadically or in association with Carney complex, an autosomal-dominant condition with germline inactivating mutations in protein kinase A, PRKAR1A. Interestingly, sporadic cases of superficial angiomyxoma also have shown loss of PRKAR1A expression on immunohistochemistry (IHC).³

Common histologic mimics of superficial angiomyxoma include aggressive angiomyxoma and angiomyofibroblastoma.⁴ It is thought that these 3 distinct tumor entities may arise from a common pluripotent cell of origin located near connective tissue vasculature, which may contribute to the similarities observed between them.⁵ For example, aggressive angiomyxomas and angiomyofibroblastomas also demonstrate a similar myxoid background and vascular proliferation that can closely mimic superficial angiomyxomas clinically. However, the vessels of superficial angiomyxomas tend to be long and thin walled, while aggressive angiomyxomas are characterized by large and thick-walled vessels and angiomyofibroblastomas by abundant smaller vessels. Additionally, unlike superficial angiomyxomas, both aggressive angiomyxomas and angiomyofibroblastomas typically occur in the genital tract of young to middle-aged women.⁶

Histopathologic examination is imperative for differentiating between superficial angiomyxoma and more aggressive histologic mimics. Superficial angiomyxomas typically consist of a rich myxoid stroma, thin-walled or arborizing blood vessels, and spindled to stellate fibroblastlike cells (quiz image 2).³ Although not prominent in our case, superficial angiomyxomas also frequently present with stromal neutrophils and epithelial components, including keratinous cysts, basaloid buds, and strands of squamous epithelium.⁷ Minimal cellular atypia, mitotic activity, and nuclear pleomorphism often are seen, with IHC negative for desmin, estrogen receptor, and progesterone receptor; positive for CD34 and smooth muscle actin; and variable for S-100 and muscle-specific actin. Although IHC has limited utility in the diagnosis of superficial angiomyxomas, it may be useful to rule out other differential diagnoses.^2,3 Superficial angiomyxomas usually show fibroblastic stromal cells, proteoglycan matrix, and collagen fibers on electron microscopy.⁸ Importantly, histopathologic examination of aggressive angiomyxoma will comparatively present with more invasive, infiltrative, and less well-circumscribed tumors.⁹ Other differential diagnoses on histology may include neurofibroma, focal cutaneous mucinosis, spindle cell lipoma, and myxofibrosarcoma. Additional considerations include fibroepithelial polyp, nevus lipomatosis, angiomyxolipoma, and anetoderma.

An important differential diagnosis in the evaluation of superficial angiomyxoma is neurofibroma, a benign peripheral nerve sheath tumor that presents as a smooth, flesh-colored, and painless papule or nodule commonly associated with the buttonhole sign. Histopathology of neurofibroma features elongated spindle cells with comma-shaped or buckled wavy nuclei and variably sized collagen bundles described as “shredded carrots” (Figure 1).¹⁰ Occasional mast cells also can be seen. Immunohistochemistry targeting elements of peripheral nerve sheaths may assist in the diagnosis of neurofibromas, including positive S-100 and SOX10 in Schwann cells, epithelial membrane antigen in perineural cells, and fingerprint positivity for CD34 in fibroblasts.¹⁰

Cutaneous mucinoses encompass a diverse group of connective tissue disorders characterized by accumulation of mucin in the skin. Solitary focal cutaneous mucinoses (FCMs) are individual isolated lesions of mucin deposits that are unassociated with systemic conditions.¹¹ Conversely, multiple FCMs presenting with multiple cutaneous lesions also have been described in association with systemic diseases such as scleroderma, systemic lupus erythematosus, and thyroid disease.¹² Solitary FCM typically presents as an asymptomatic, flesh-colored papule or nodule on the extremities. It often arises in mid to late adulthood with a slightly increased frequency among males.¹² Histopathology of solitary FCM commonly demonstrates a dome-shaped pool of basophilic mucin in the upper dermis sparing involvement of the underlying subcutaneous tissue (Figure 2).¹³ Notably, FCM often lacks the vascularity as well as stromal neutrophils and epithelial elements that are seen in superficial angiomyxomas. Although hematoxylin and eosin stains can be sufficient for diagnosis of solitary FCM, additional stains for mucin such as Alcian blue, colloidal iron, or toluidine blue also may be considered to support the diagnosis.¹²

Spindle cell lipomas (SCLs) are rare, benign, subcutaneous, adipocytic tumors that arise on the upper back, posterior neck, or shoulders of middle-aged or elderly adult males.¹⁴ The clinical presentation often is an asymptomatic, well-circumscribed, mobile subcutaneous mass that is firmer than a common lipoma. Histologically, SCLs are characterized by mature adipocytes, spindle cells, and wire or ropelike collagen fibers in a myxoid background (Figure 3). The spindle cells usually are bland with a notable bipolar shape and blunted ends. Infiltrative growth patterns or mitotic figures are uncommon. Diagnosis can be supported by IHC, as SCLs stain diffusely positive for CD34 with loss of the retinoblastoma protein.⁷

Another important differential diagnosis to consider is myxofibrosarcoma, a rare and malignant myxoid cutaneous tumor. Clinically, it presents asymptomatically as an indolent, slow-growing nodule on the limbs and limb girdles.⁷ Histopathologic features demonstrate a multilobular tumor composed of a mixture of hypocellular and hypercellular regions with incomplete fibrous septae (Figure 4). The presence of curvilinear vasculature is characteristic. Multinucleated giant cells and cellular atypia with nuclear pleomorphism also can be seen. Although IHC findings generally are not specific, they can be used to rule out other potential diagnoses. Myxofibrosarcomas stain positive for vimentin and occasionally smooth muscle actin, muscle-specific actin, and CD34.⁷

Superficial angiomyxomas are benign; however, excision is recommended to distinguish between mimics. Local recurrence after excision is common in 30% to 40% of patients.¹⁵ Mohs micrographic surgery has been considered, especially if the following are present: tumor characteristics (eg, poorly circumscribed), location (eg, head and neck or other cosmetically or functionally sensitive areas), and likelihood of recurrence (high for superficial angiomyxomas). 16 This case otherwise highlights a rare example of superficial angiomyxomas involving the buttocks.

Sleep deprivation can increase emotional distress and mood disorders; reduce quality of life; and lead to cognitive, memory, and performance deficits.¹ Military service predisposes members to disordered sleep due to the rigors of deployments and field training, such as long shifts, shift changes, stressful work environments, and time zone changes. Evidence shows that sleep deprivation is associated with cardiovascular disease, gastrointestinal disease, and some cancers.² We explore multiple mechanisms by which sleep deprivation may affect the skin. We also review the potential impacts of sleep deprivation on specific topics in dermatology, including atopic dermatitis (AD), psoriasis, alopecia areata, physical attractiveness, wound healing, and skin cancer.

Sleep and Military Service

Approximately 35.2% of Americans experience short sleep duration, which the Centers for Disease Control and Prevention defines as sleeping fewer than 7 hours per 24-hour period.³ Short sleep duration is even more common among individuals working in protective services and the military (50.4%).⁴ United States military service members experience multiple contributors to disordered sleep, including combat operations, shift work, psychiatric disorders such as posttraumatic stress disorder, and traumatic brain injury.⁵ Bramoweth and Germain⁶ described the case of a 27-year-old man who served 2 combat tours as an infantryman in Afghanistan, during which time he routinely remained awake for more than 24 hours at a time due to night missions and extended operations. Even when he was not directly involved in combat operations, he was rarely able to keep a regular sleep schedule.⁶ Service members returning from deployment also report decreased sleep. In one study (N=2717), 43% of respondents reported short sleep duration (<7 hours of sleep per night) and 29% reported very short sleep duration (<6 hours of sleep per night).⁷ Even stateside, service members experience acute sleep deprivation during training.⁸

Sleep and Skin

The idea that skin conditions can affect quality of sleep is not controversial. Pruritus, pain, and emotional distress associated with different dermatologic conditions have all been implicated in adversely affecting sleep.⁹ Given the effects of sleep deprivation on other organ systems, it also can affect the skin. Possible mechanisms of action include negative effects of sleep deprivation on the hypothalamic-pituitary-adrenal (HPA) axis, cutaneous barrier function, and immune function. First, the HPA axis activity follows a circadian rhythm.¹⁰ Activation outside of the bounds of this normal rhythm can have adverse effects on sleep. Alternatively, sleep deprivation and decreased sleep quality can negatively affect the HPA axis.¹⁰ These changes can adversely affect cutaneous barrier and immune function.¹¹ Cutaneous barrier function is vitally important in the context of inflammatory dermatologic conditions. Transepidermal water loss, a measurement used to estimate cutaneous barrier function, is increased by sleep deprivation.¹² Finally, the cutaneous immune system is an important component of inflammatory dermatologic conditions, cancer immune surveillance, and wound healing, and it also is negatively impacted by sleep deprivation.¹³ This framework of sleep deprivation affecting the HPA axis, cutaneous barrier function, and cutaneous immune function will help to guide the following discussion on the effects of decreased sleep on specific dermatologic conditions.

Atopic Dermatitis—Individuals with AD are at higher odds of having insomnia, fatigue, and overall poorer health status, including more sick days and increased visits to a physician.¹⁴ Additionally, it is possible that the relationship between AD and sleep is not unidirectional. Chang and Chiang¹⁵ discussed the possibility of sleep disturbances contributing to AD flares and listed 3 possible mechanisms by which sleep disturbance could potentially flare AD: exacerbation of the itch-scratch cycle; changes in the immune system, including a possible shift to helper T cell (T_H2) dominance; and worsening of chronic stress in patients with AD. These changes may lead to a vicious cycle of impaired sleep and AD exacerbations. It may be helpful to view sleep impairment and AD as comorbid conditions requiring co-management for optimal outcomes. This perspective has military relevance because even without considering sleep deprivation, deployment and field conditions are known to increase the risk for AD flares.¹⁶

Psoriasis—Psoriasis also may have a bidirectional relationship with sleep. A study utilizing data from the Nurses’ Health Study showed that working a night shift increased the risk for psoriasis.¹⁷ Importantly, this connection is associative and not causative. It is possible that other factors in those who worked night shifts such as probable decreased UV exposure or reported increased body mass index played a role. Studies using psoriasis mice models have shown increased inflammation with sleep deprivation.¹⁸ Another possible connection is the effect of sleep deprivation on the gut microbiome. Sleep dysfunction is associated with altered gut bacteria ratios, and similar gut bacteria ratios were found in patients with psoriasis, which may indicate an association between sleep deprivation and psoriasis disease progression.¹⁹ There also is an increased association of obstructive sleep apnea in patients with psoriasis compared to the general population.²⁰ Fortunately, the rate of consultations for psoriasis in deployed soldiers in the last several conflicts has been quite low, making up only 2.1% of diagnosed dermatologic conditions,²¹ which is because service members with moderate to severe psoriasis likely will not be deployed.

Alopecia Areata—Alopecia areata also may be associated with sleep deprivation. A large retrospective cohort study looking at the risk for alopecia in patients with sleep disorders showed that a sleep disorder was an independent risk factor for alopecia areata.²² The impact of sleep on the HPA axis portrays a possible mechanism for the negative effects of sleep deprivation on the immune system. Interestingly, in this study, the association was strongest for the 0- to 24-year-old age group. According to the 2020 demographics profile of the military community, 45% of active-duty personnel are 25 years or younger.²³ Fortunately, although alopecia areata can be a distressing condition, it should not have much effect on military readiness, as most individuals with this diagnosis are still deployable.

Physical Appearance—Studies where raters evaluate photographs of sleep-deprived and well-rested individuals have shown that sleep-deprived individuals are more likely to be perceived as looking sad and/or having hanging eyelids, red and/or swollen eyes, wrinkles around the eyes, dark circles around the eyes, pale skin, and/or droopy corners of the mouth.²⁴ Additionally, raters indicated that they perceived the sleep-deprived individuals as less attractive, less healthy, and more sleepy and were less inclined to socialize with them.²⁵ Interestingly, attempts to objectively quantify the differences between the 2 groups have been less clear.^26,27 Although the research is not yet definitive, it is feasible to assume that sleep deprivation is recognizable, and negative perceptions may be manifested about the sleep-deprived individual’s appearance. This can have substantial social implications given the perception that individuals who are viewed as more attractive also tend to be perceived as more competent.²⁸ In the context of the military, this concept becomes highly relevant when promotions are considered. For some noncommissioned officer promotions in the US Army, the soldier will present in person before a board of superiors who will “determine their potential to serve at the recommended rank.” Army doctrine instructs the board members to “consider the Soldier’s overall personal appearance, bearing, self-confidence, oral expression and conversational skills, and attitude when determining each Soldier’s potential.”²⁹ In this context, a sleep-deprived soldier would be at a very real disadvantage for a promotion based on their appearance, even if the other cognitive effects of sleep deprivation are not considered.

Final Thoughts

Although more research is needed, there is evidence that sleep deprivation can negatively affect the skin. Randomized controlled trials looking at groups of individuals with specific dermatologic conditions with a very short sleep duration group (<6 hours of sleep per night), short sleep duration group (<7 hours of sleep per night), and a well-rested group (>7 hours of sleep per night) could be very helpful in this endeavor. Possible mechanisms include the HPA axis, immune system, and skin barrier function that are associated with sleep deprivation. Specific dermatologic conditions that may be affected by sleep deprivation include AD, psoriasis, alopecia areata, physical appearance, wound healing, and skin cancer. The impact of sleep deprivation on dermatologic conditions is particularly relevant to the military, as service members are at an increased risk for short sleep duration. It is possible that improving sleep may lead to better disease control for many dermatologic conditions.
