FLT3-ligand (FLT3-L) levels exceeding 92 pg/mL in bone marrow and 121 pg/mL in peripheral blood are associated with relapsed and refractory disease in patients with multiple myeloma, Normann Steiner, MD, and his colleagues report in a study published in PLoS ONE.

In the study of 14 patients with monoclonal gamm opathy of undetermined significance (MGUS), 42 patients with newly diagnosed myeloma, and 27 patients with relapsed/refractory myeloma, there was a 61% probability that patients with FLT3-L levels above 92 pg/mL in bone marrow had relapsed or refractory multiple myeloma and a 79% probability that those with FLT3-L levels of 92 pg/mL or less had not relapsed and were not refractory. Based on FLT3-L levels in peripheral blood, values of 121 pg/mL or more were associated with a 71% probability of relapsed or refractory disease. The likelihood of not having relapses or refractory disease was 87% for patients with values less than 121 pg/mL.

“FLT3-L could be useful as a marker to identify (relapsed or refractory multiple myeloma) patients and should be evaluated as a potential target for future therapy strategies,” Dr. Steiner of Innsbruck (Austria) Medical University, and his fellow researchers wrote in PLoS ONE.

The researchers obtained bone marrow aspirates from all patients. Peripheral blood was examined from 4 MGUS patients, 31 patients with newly diagnosed myeloma, and 16 patients with relapsed or refractory myeloma. Peripheral blood was also obtained from 16 control subjects.

The levels of four potential risk factors were measured – soluble TIE2, FLT3-L, endostatin, and osteoactivin. The most significant association with risk was seen with FLT3-L levels.

Expression of soluble TIE2 in bone marrow differed significantly among the three patient cohorts and may be driven by the same factors that influence FLT3-L levels. However, soluble TIE2 levels were not as effective at differentiating patients at risk for disease progression, the researchers wrote.

Soluble TIE2 expression in bone marrow was highest in MGUS patients (median 4003.97 pg/mL) in comparison to relapsed or refractory disease (median 2223.26 pg/mL; P = .03) and to newly diagnosed patients with myeloma (median 861.98 pg/mL; P less than .001). A statistically significant difference among bone marrow levels of soluble TIE2 was observed for newly diagnosed patients and those with relapsed or refractory disease (P = .03).

However, soluble TIE2 in peripheral blood plasma did not differ significantly in the three cohorts nor did it differ between patients and controls.

In contrast to TIE2 and FLT3-L, levels of endostatin were lowest (median 146.50 ng/mL) in bone marrow plasma samples of patients with relapsed or refractory disease. Levels were higher in MGUS patients (median 190.37 mg/dL) than in newly diagnosed myeloma patients (median 170.15 mg/mL; P = .5).

Similar to soluble TIE2, plasma levels of endostatin in peripheral blood did not differ significantly in the three patient cohorts. Measurements of endostatin in bone marrow and peripheral blood correlated significantly (P less than .001), and peripheral blood levels differed significantly (P less than .001) for patients and control persons.

Osteoactivin expression was highest in the MGUS cohort, with median bone marrow plasma levels of 36 ng/mL as compared with median levels of 24.92 ng/mL in newly diagnosed myeloma patients and 22.30 ng/mL in patients with relapsed or refractory myeloma. Osteoactivin levels in peripheral blood did not differ significantly in the three cohorts, but differed between patients and control subjects. Osteoactivin measures in bone marrow and peripheral blood correlated significantly.

LONDON – Twelve modifiable risk factors appear to account for more than half of the variation in dementia risk associated with socioeconomic status.

When integrated into an 18-point risk score, dubbed the “Lifestyle for Brain Health” (LIBRA) index, they accurately predicted dementia risk in more than 6,300 subjects who were followed for 7 years: Dementia risk increased by 30% for every 1-point increase on the LIBRA score, Sebastian Koehler, PhD, said at the Alzheimer’s Association International Conference.

• Diabetes.

• Hypertension.

• High cholesterol.

• Smoking.

• Obesity.

• Physical inactivity.

• Depression.

• Coronary heart disease.

• Kidney disease.

• Diet.

• Alcohol.

• Mental activity.

Dr. Koehler and his colleagues used them to create the weighted LIBRA score, which computes an 18-point risk level ranging from –5.9 (lower risk) to 12.7 (higher risk). Among the factors that reduce dementia risk are high cognitive activity, healthy diet or Mediterranean diet, and low-moderate alcohol intake. The others all increased risk. Each of the factors was assigned a point value based on its percentage of risk reduction or increase. For example, high cognitive activity reduced risk by more than 3 points, but depression increased it by 2 points. The investigators then validated this score on 6,346 participants in the English Longitudinal Study of Ageing, who were followed for up to 7 years.

Dr. Koehler’s study, however, was not just a LIBRA validation study. He wanted to correlate these protective and endangering factors with each subject’s socioeconomic status, and determine how much of the risk difference generally accredited to wealth was related to the LIBRA factors.

After 7 years, about 9% of the study sample developed incident dementia. These subjects were significantly older than those who didn’t (77 vs. 64 years). They were more likely to have lower education attainment (58% vs. 37%), and more likely to be poor (44% vs. 29%).

On the LIBRA risk factors, the participants who developed dementia were significantly more likely to have heart disease, diabetes, hypercholesterolemia, hypertension, and depression, although not significantly more likely to be obese or to smoke.

On the LIBRA protective factors, they were significantly less likely to be low-moderate alcohol users (37% vs. 57%), to have high cognitive activity (17% vs. 45%), and significantly more likely to be physically inactive (59% vs. 24%).

Two survival curves compared the incidence of dementia related to wealth and LIBRA score. Subjects of low socioeconomic status experienced an increase in dementia risk very similar to those with high LIBRA scores. Dr. Koehler also conducted three analyses that examined the effects of wealth on dementia risk: the total effect of wealth, the direct effect of wealth, and what he called the “indirect wealth effect.” This examined the impact of wealth on LIBRA scores, followed by the effect of these scores on dementia risk.

This final model concluded that 56% of the risk imposed by low socioeconomic status was actually attributable to LIBRA scores. In other words, low socioeconomic status was directly tied to both increases in physical and mental risk factors, and decreases in physical and mental protective factors.

“Health inequalities influencing dementia risk exist because of socioeconomic differences between people,” Dr. Koehler said. “People with less wealth have a higher frequency of being exposed to risk factors for dementia that are potentially treatable.”

The LIBRA study is part of a larger dementia prevention study called Innovative, Midlife Intervention for Dementia Deterrence (In-MINDD). Dr. Koehler had no financial disclosures.

LONDON – Twelve modifiable risk factors appear to account for more than half of the variation in dementia risk associated with socioeconomic status.

When integrated into an 18-point risk score, dubbed the “Lifestyle for Brain Health” (LIBRA) index, they accurately predicted dementia risk in more than 6,300 subjects who were followed for 7 years: Dementia risk increased by 30% for every 1-point increase on the LIBRA score, Sebastian Koehler, PhD, said at the Alzheimer’s Association International Conference.

In findings that are being hailed as practice changing, men with metastatic prostate cancer had a near 40% lower risk of death when they were treated with a combination of abiraterone acetate (Zytiga), androgen deprivation therapy, and prednisone or prednisolone, compared with ADT alone.

After a median follow-up of 30.4 months, median overall survival for men with newly diagnosed metastatic, castration-sensitive prostate cancer treated with ADT plus dual placebos was 34.7 months, vs. not reached for men treated with ADT, abiraterone, and prednisone in the LATITUDE trial. Similarly, in the STAMPEDE trial, men with newly diagnosed locally advanced or metastatic disease who were randomized to ADT with abiraterone and prednisolone had a 37% reduction in their risk for death and a 79% reduction in their risk for treatment failure, compared with men randomized to ADT alone.

roobcio/Thinkstock.com

The LATITUDE trial

LATITUDE investigators from 235 sites in 34 countries in Europe, Asia/Pacific, Latin America and Canada enrolled 1,199 patients with newly diagnosed metastatic castration-sensitive prostate cancer and randomly assigned them to receive either abiraterone and prednisone plus ADT (597 patients), or ADT plus dual placebos (602).

At a planned interim analysis at a median follow-up of 30.4 months, after 406 patients had died, median OS, a co-primary end point, had not been reached among patients in the abiraterone group, compared with 34.7 months for patients assigned to ADT/placebo. This difference translates into a hazard ratio for death of 0.62 (P less than .001).

The median duration of radiographic progression-free survival (PFS), the other primary end point, was 33.0 months among patients treated with abiraterone vs. 14.8 months for those treated with placebo (HR for disease progression or death, 0.47; P less than .001)

Abiraterone was also associated with significantly better outcomes in all secondary endpoints, including time until pain progression, subsequent therapy, initiation of chemotherapy, and prostate-specific antigen (PSA) progression (P less than .001 for each comparison).

The frequency of adverse events leading to treatment discontinuation was 12% for patients in the abiraterone group vs. 10% for those in the placebo group. Rates of grade 3 or 4 hypertension and hypokalemia were higher among patients who received abiraterone.

Based on the trial results, the independent data and safety monitoring committee unanimously recommended unblinding of the trial and allowing patients in the placebo group to receive abiraterone.

The STAMPEDE trial

The STAMPEDE (Systemic Therapy in Advancing or Metastatic Prostate Cancer: Evaluation of Drug Efficacy) trial was designed to test whether adding other therapies to ADT can improve OS in the first-line setting for men with locally advanced or metastatic prostate cancer.

The investigators enrolled 1,917 patients with either newly diagnosed node-positive or metastatic prostate cancer, high-risk locally advanced disease, or relapsed, high-risk disease following radical surgery or radiotherapy.

In all, 95% of patients had newly diagnosed disease; 52% had metastatic disease, 20% had node-positive or node-indeterminate nonmetastatic disease, and 28% had node-negative nonmetastatic disease.

After a median follow-up of 40 months, there had been 184 deaths among the 960 patients assigned to received ADT plus abiraterone and prednisolone, compared with 262 deaths among 957 patients assigned to ADT alone. The respective 3-year survival rates were 83% vs. 76%, translating into a HR of 0.63 (P less than .001) favoring abiraterone. The respective hazard ratios for abiraterone in patients with metastatic and nonmetastatic disease were 0.75 and 0.61, respectively.

Failure-free survival (no radiologic, clinical, or prostate-specific antigen progression or prostate cancer death) also favored abiraterone, with a HR of 0.29, compared with ADT alone (P less than .001). The respective hazard ratios for patients with nonmetastatic disease and metastatic disease were 0.21 and 0.31, respectively.

Grade 3 or greater adverse events occurred in 47% of patients on abiraterone, and in 33% of patients treated with ADT alone. There nine deaths on treatment in the abiraterone group, including two cases of pneumonia (one with sepsis), two strokes, and one case each of dyspnea, lower respiratory tract infection, liver failure, pulmonary hemorrhage, and chest infections.

There were three deaths in the ADT alone group, two from myocardial infarctions and one from bronchopneumonia.

Similarly, in the STAMPEDE trial, men with newly diagnosed locally advanced or metastatic disease who were randomized to ADT with abiraterone and prednisolone had a 37% reduction in their risk for death and a 79% reduction in their risk for treatment failure, compared with men randomized to ADT alone.

The LATITUDE trial

LATITUDE investigators from 235 sites in 34 countries in Europe, Asia/Pacific, Latin America and Canada enrolled 1,199 patients with newly diagnosed metastatic castration-sensitive prostate cancer and randomly assigned them to receive either abiraterone and prednisone plus ADT (597 patients), or ADT plus dual placebos (602).

At a planned interim analysis at a median follow-up of 30.4 months, after 406 patients had died, median OS, a co-primary end point, had not been reached among patients in the abiraterone group, compared with 34.7 months for patients assigned to ADT/placebo. This difference translates into a hazard ratio for death of 0.62 (P less than .001).

The median duration of radiographic progression-free survival (PFS), the other primary end point, was 33.0 months among patients treated with abiraterone vs. 14.8 months for those treated with placebo (HR for disease progression or death, 0.47; P less than .001)

Abiraterone was also associated with significantly better outcomes in all secondary endpoints, including time until pain progression, subsequent therapy, initiation of chemotherapy, and prostate-specific antigen (PSA) progression (P less than .001 for each comparison).

The frequency of adverse events leading to treatment discontinuation was 12% for patients in the abiraterone group vs. 10% for those in the placebo group. Rates of grade 3 or 4 hypertension and hypokalemia were higher among patients who received abiraterone.

Based on the trial results, the independent data and safety monitoring committee unanimously recommended unblinding of the trial and allowing patients in the placebo group to receive abiraterone.

The STAMPEDE trial

The STAMPEDE (Systemic Therapy in Advancing or Metastatic Prostate Cancer: Evaluation of Drug Efficacy) trial was designed to test whether adding other therapies to ADT can improve OS in the first-line setting for men with locally advanced or metastatic prostate cancer.

The investigators enrolled 1,917 patients with either newly diagnosed node-positive or metastatic prostate cancer, high-risk locally advanced disease, or relapsed, high-risk disease following radical surgery or radiotherapy.

In all, 95% of patients had newly diagnosed disease; 52% had metastatic disease, 20% had node-positive or node-indeterminate nonmetastatic disease, and 28% had node-negative nonmetastatic disease.

After a median follow-up of 40 months, there had been 184 deaths among the 960 patients assigned to received ADT plus abiraterone and prednisolone, compared with 262 deaths among 957 patients assigned to ADT alone. The respective 3-year survival rates were 83% vs. 76%, translating into a HR of 0.63 (P less than .001) favoring abiraterone. The respective hazard ratios for abiraterone in patients with metastatic and nonmetastatic disease were 0.75 and 0.61, respectively.

Failure-free survival (no radiologic, clinical, or prostate-specific antigen progression or prostate cancer death) also favored abiraterone, with a HR of 0.29, compared with ADT alone (P less than .001). The respective hazard ratios for patients with nonmetastatic disease and metastatic disease were 0.21 and 0.31, respectively.

Grade 3 or greater adverse events occurred in 47% of patients on abiraterone, and in 33% of patients treated with ADT alone. There nine deaths on treatment in the abiraterone group, including two cases of pneumonia (one with sepsis), two strokes, and one case each of dyspnea, lower respiratory tract infection, liver failure, pulmonary hemorrhage, and chest infections.

There were three deaths in the ADT alone group, two from myocardial infarctions and one from bronchopneumonia.

An elevated baseline neutrophil-to-lymphocyte ratio (NLR) was associated with a poor 1-year mortality rate in hospitalized primary biliary cholangitis (PBC) patients, according to Lin Lin, MD, of Tianjin (China) Medical University General Hospital and the Tianjin Institute of Digestive Diseases and associates.

A retrospective analysis of 88 PBC patients hospitalized between June 2009 and January 2014 was performed for the study. NLR was a significant predictor of survival, with an odds ratio of 1.5, a sensitivity of 100%, and a specificity of 67.1%. A baseline NLR value of 2.18 was selected as the cutoff for 1-year mortality. Of the 33 patients above this value at initial hospitalization, 6 died, whereas none of the 55 patients below this value died.

The results of the retrospective study were confirmed in a prospective 1-year cohort that included 63 people with PBC. The patients with a baseline NLR of less than 2.18 had significantly longer survival times than those who had a baseline NLR of 2.18 or higher.

“NLR – an affordable, widely available and reproducible index – is closely related to short-term mortality in patients with PBC. Further studies are warranted to externally cross-validate our findings in other populations,” the investigators concluded.

The combined use of vancomycin and a beta-lactam antibiotic for prophylaxis against surgical site infections is associated with both benefits and harms, according to findings from a national propensity-score–adjusted retrospective cohort study.

For example, the combination treatment reduced surgical site infections (SSIs) 30 days after cardiac surgical procedures but increased the risk of postoperative acute kidney injury (AKI) in some patients, Westyn Branch-Elliman, MD, of the VA Boston Healthcare System and her colleagues reported online July 10 in PLOS Medicine.

SSI benefit with combination therapy

“After controlling for age, diabetes, ASA [American Society of Anesthesiologists] score, mupirocin administration, current smoking status, and preoperative MRSA [methicillin-resistant Staphylococcus aureus] colonization status, receipt of combination antimicrobial prophylaxis was associated with reduced SSI risk following cardiac surgical procedures (adjusted risk ratio, 0.61),” they wrote, noting that, when combination therapy was compared with either of the agents alone, the associations were similar and that no association between SSI reduction and the combination regimen was seen for the other types of surgical procedures assessed.

Secondary analyses showed that, among the cardiac patients, differences in the rates of SSIs were seen based on MRSA status in patients undergoing cardiac surgery. Among MRSA-colonized patients, SSIs occurred in 8 of 346 patients (2.3%) who received combination prophylaxis vs. 4 of 100 patients (4%) who received vancomycin alone (aRR, 0.53), and, among MRSA-negative and MRSA-unknown cardiac surgery patients, SSIs occurred in 58 of 6,607 patients (0.88%) receiving combination prophylaxis and 146 of 10,215 patients (1.4%) receiving a beta-lactam alone (aRR, 0.60).

“Among MRSA-colonized patients undergoing cardiac surgery, the associated absolute risk reduction for SSI was approximately triple that of the absolute risk reduction in MRSA-negative or -unknown patients, with a [number needed to treat] to prevent 1 SSI of 53 for the MRSA-colonized group, compared with 176 for the MRSA-negative or -unknown groups,” they wrote.

The incidence of Clostridium difficile infection was similar in both exposure groups (0.72% and 0.81% with combination and single agent prophylaxis, respectively).

Higher AKI risk with combination therapy

“In contrast, combination versus single prophylaxis was associated with higher relative risk of AKI in the 7-day postoperative period after adjusting for prophylaxis regimen duration, age, diabetes, ASA score, and smoking,” they said.

The rate of AKI was 23.75% among patients receiving combination prophylaxis, compared with 20.79% and 13.93% among those receiving vancomycin alone and a beta-lactam alone, respectively.

Significant associations between absolute risk of AKI and receipt of combination regimens were seen across all types of procedures, the investigators said.

“Overall, the NNH [number needed to harm] to cause one episode of AKI in cardiac surgery patients receiving combination therapy was 22, and, for stage 3 AKI, 167. The NNH associated with one additional episode of any postoperative AKI after receipt of combination therapy was 76 following orthopedic procedures and 25 following vascular surgical procedures,” they said.

The optimal approach for preventing SSIs is unclear. Although the multidisciplinary Clinical Practice Guidelines for Antimicrobial Prophylaxis in Surgery recommend single agent prophylaxis most often, with a beta-lactam antibiotic, for most surgical procedures, the use of vancomycin alone is a consideration in MRSA-colonized patients and in centers with a high MRSA incidence, and combination prophylaxis with a beta-lactam plus vancomycin is increasing. However, the relative risks and benefit of this strategy have not been carefully studied, the investigators said.

Thus, the investigators used a propensity-adjusted, log-binomial regression model stratified by type of surgical procedure among the cases identified in the Veterans Affairs cohort to assess the association between SSIs and receipt of combination prophylaxis versus single agent prophylaxis.

Though limited by the observational study design and by factors such as a predominantly male and slightly older and more rural population, the findings suggest that “clinicians may need to individualize prophylaxis strategy based on patient-specific factors that influence the risk-versus-benefit equation,” they said, concluding that “future studies are needed to evaluate the utility of MRSA screening protocols for optimizing and individualizing surgical prophylaxis regimen.”

This study was funded by Veterans Affairs Health Services Research and Development. Dr. Branch-Elliman reported having no disclosures. One other author, Eli Perencevich, MD, received an investigator initiated Grant from Merck Pharmaceuticals in 2013.

Gastroparesis is defined as delayed gastric emptying with associated symptoms in the absence of mechanical obstruction. The cardinal symptoms are upper abdominal pain, postprandial fullness, bloating, early satiety, nausea, and, with more severe disease, vomiting. Weight loss, malnutrition, dehydration, electrolyte imbalance, bezoar formation, and aspiration pneumonia may occur in advanced cases. Unfortunately, there are few approved or efficacious treatment options for diabetic gastroparesis. The 5-HT₄ receptor agonist, cisapride, has been withdrawn from the prescription markets in most countries.

An association between steatocystoma multiplex (SCM) and eruptive vellus hair cysts (EVHCs) has been recognized. They are related conditions representing nevoid malformations of the pilosebaceous junctions^1-10 that have similar clinical features but distinctive histologic features. Both conditions most commonly involve the anterior aspect of the chest. Six cases of a rare facial variant of SCM have been reported,^11-16 3 involving lesions limited to the forehead.^13-15 Two patients with a rare facial variant of EVHC also have been reported.¹⁷ The development of separate lesions of SCM and EVHC on the trunk can uncommonly occur.^5,6,10 One case of SCM and EVHC on the forehead has been described.³ Other types of benign follicular neoplasms simultaneously developing in association with SCM or EVHC also are rare. The simultaneous occurrence of multiple trichoblastomas, trichoepitheliomas, and SCM on the face and trunk has been reported in 1 case.¹⁸ Milia, SCM, and EVHC on the face and trunk have been reported in 1 family.⁴ A report of facial steatocystoma associated with a pilar cyst and bilateral preauricular sinus also has occurred in 1 patient.¹⁹ Here, we report the simultaneous occurrence of SCM, EVHC, and trichofolliculomas localized to the forehead.

Case Report

A 37-year-old man had an increasing number of flesh-colored to yellow papules on the forehead that had been present since puberty. Although the lesions were asymptomatic, some had recently become tender, which led him to seek medical care. There was no history of trauma, burns, irradiation, or application of topical agents to the area or use of eyeglasses or goggles. The patient’s father had similar lesions limited to the forehead, which developed during adolescence.

On evaluation at our clinic, skin examination revealed 16 discrete, 0.3- to 1-cm, flesh-colored, yellow to blue, mobile, smooth papules, as well as flesh-colored papules with a central black punctum, on the forehead (Figure 1). Similar lesions were not present on the rest of the face; around the ears; or on the scalp, neck, chest, back, abdomen, genitalia, buttocks, palms, soles, axillae, arms, or legs. There were no nail abnormalities.

Multiple 3-, 4-, and 6-mm punch and excisional biopsies were performed to remove all 16 lesions on the forehead. Histologic examination revealed a collapsed cystic structure in the mid dermis in 10 lesions. The cysts were lined with a squamous epithelium without a granular layer but with an eosinophilic corrugated lining, and the cyst cavity contained scant homogeneous eosinophilic secretion. Mature sebaceous glands were adjacent to the outer portion of the cyst wall. These histologic findings were consistent with SCM (Figure 2).

In 3 lesions, histologic examination revealed a cystic structure lined by a few layers of stratified squamous epithelium in the mid dermis. The cyst cavity contained numerous small vellus hairs and laminated keratin. These histologic findings were consistent with EVHC (Figure 3).

In the other 3 lesions, histologic examination revealed a dilated central cystic cavity filled with laminated keratin in the mid dermis. Multiple small follicles arose from the cysts and showed differentiation toward germinative epithelium. The surrounding stroma was fibrotic and contained a patchy lymphocytic infiltrate. These histologic findings were consistent with trichofolliculomas (Figure 4).

Comment

Characteristics of SCM
Steatocystoma multiplex is an uncommon condition characterized by the formation of asymptomatic, 0.2- to 2-cm, yellow to flesh-colored, soft, mobile papules or nodules on the trunk, extremities, axillae, genitalia, and/or chest. The lesions contain a clear or opaque, oily, milky or yellow, odorless fluid and most commonly are located on the anterior aspect of the chest. The face is not a commonly involved site in this condition. Six cases of a rare facial variant of SCM have been reported,^11-16 with lesions limited to the forehead in 3 cases.^13-15

In 1937, Mount²⁰ credited Bozellini for describing the first case, though 3 cases reported in the late 1800s probably were SCM.²¹ In 1899, Pringle²² coined the term steatocystoma multiplex for this condition. It can be sporadic or have an autosomal-dominant inheritance pattern. Steatocystoma multiplex can occur at any age, though lesions develop most frequently in adolescence or young adulthood. There is no sex predilection.

Steatocystoma multiplex with pachyonychia congenita has been reported in a familial case.²³ Other findings reported in patients with SCM include ichthyosis, koilonychia, acrokeratosis verruciformis of Hopf and hypertrophic lichen planus, hidradenitis suppurativa, hypotrichosis, multiple keratoacanthomas, and rheumatoid arthritis.^12,24-26

Steatocystoma multiplex is a cyst lined by stratified squamous epithelium without a granular layer but with a thick eosinophilic cuticle. Mature sebaceous lobules are closely associated with the cyst wall. Steatocystoma multiplex arises from the sebaceous duct because the lining of the lumen is composed of undulating eosinophilic cuticle.

Characteristics of EVHCs
Eruptive vellus hair cysts, which were first described by Esterly et al,²⁷ can occur at any age but develop most frequently in adolescents or young adults. Sometimes the lesions are congenital or appear in childhood. There is no sex predilection. They can be sporadic or have an autosomal-dominant inheritance pattern.

Eruptive vellus hair cysts are asymptomatic, 1- to 2-mm, smooth, crusted, or umbilicated papules on the chest or arms and legs. Eruptive vellus hair cysts most commonly involve the anterior aspect of the chest. The lesions are flesh-colored to yellow, though they have a slate gray color in darker-skinned individuals. A rare facial variant has been reported in 2 patients of Asian descent.¹⁷

Eruptive vellus hair cysts are small cystic structures lined by a stratified squamous epithelium with a granular layer. The cyst cavity contains numerous small vellus hair shafts and laminated keratin. Eruptive vellus hair cysts originate from the infundibulum or less frequently the isthmus or infundibular-isthmic junction of the hair follicle.

Characteristics of Trichofolliculomas
Trichofolliculomas are solitary, 3- to 5-mm, flesh-colored papules that occur on the face. They are highly differentiated, benign, neoplastic proliferations of an actively trichogenic epithelium, with structural components reflecting all portions of the pilosebaceous unit. Trichofolliculomas consist of a central dilated primary follicle contiguous with the surface epidermis embedded in a fibrous stroma. Multiple small secondary follicles with varying degrees of follicular differentiation arise from the primary follicle.

Co-occurrence of Lesions
An association between SCM and EVHC has been recognized.^5-10 Steatocystoma multiplex and EVHC have similar clinical features but distinctive histologic features. They also have a similar age of onset, location/appearance of lesions, and mode of inheritance. Steatocystoma multiplex and EVHC can be distinguished by immunohistochemical techniques: SCM shows expression of keratin 10 and keratin 17, whereas EVHCs express only keratin 17.²⁸

Steatocystoma multiplex and EVHC have only rarely been reported to occur together on the trunk. One case of SCM and EVHC occurring on the forehead has been described.³ Other types of benign follicular neoplasms simultaneously developing in association with SCM or EVHC also are rare. Milia, SCM, and EVHC on the face and trunk have been reported in 1 family,⁴ and facial steatocystoma associated with a pilar cyst and bilateral preauricular sinus was reported in 1 patient.¹⁹ Although trichofolliculomas have not been reported to occur with SCM or EVHC, 2 related follicular neoplasms—trichoepitheliomas and trichoblastomas—have been reported to occur in association with SCM on the face and chest and around the ears in 1 case.¹⁸

Differential Diagnosis
The clinical differential diagnosis includes multiple epidermoid cysts, dermoid cysts, Gardner syndrome, sebaceous adenomas, Muir-Torre syndrome, syringomas, milia, leiomyomas, lipomas, acneiform folliculitis, multiple familial and nonfamilial trichoepitheliomas, cylindromas, and angiofibromas.^3,29

Conclusion

Our patient represents a rare case of simultaneous occurrence of SCM, EVHC, and trichofolliculomas localized to the forehead. The patient had multiple neoplasms involving differentiation toward various regions of the pilosebaceous unit. This case gives further support to the hypothesis that these benign follicular neoplasms are closely related but are distinct conditions within the spectrum of the same disease process. They represent nevoid malformations of the pilosebaceous unit that can be sporadic or inherited in an autosomal-dominant pattern. Pure types of these lesions may represent one end of the spectrum, but in some patients, there are overlapping features or hybrids of each condition. Several biopsies from patients with multiple lesions should be performed to establish an accurate diagnosis.

An association between steatocystoma multiplex (SCM) and eruptive vellus hair cysts (EVHCs) has been recognized. They are related conditions representing nevoid malformations of the pilosebaceous junctions^1-10 that have similar clinical features but distinctive histologic features. Both conditions most commonly involve the anterior aspect of the chest. Six cases of a rare facial variant of SCM have been reported,^11-16 3 involving lesions limited to the forehead.^13-15 Two patients with a rare facial variant of EVHC also have been reported.¹⁷ The development of separate lesions of SCM and EVHC on the trunk can uncommonly occur.^5,6,10 One case of SCM and EVHC on the forehead has been described.³ Other types of benign follicular neoplasms simultaneously developing in association with SCM or EVHC also are rare. The simultaneous occurrence of multiple trichoblastomas, trichoepitheliomas, and SCM on the face and trunk has been reported in 1 case.¹⁸ Milia, SCM, and EVHC on the face and trunk have been reported in 1 family.⁴ A report of facial steatocystoma associated with a pilar cyst and bilateral preauricular sinus also has occurred in 1 patient.¹⁹ Here, we report the simultaneous occurrence of SCM, EVHC, and trichofolliculomas localized to the forehead.

Case Report

A 37-year-old man had an increasing number of flesh-colored to yellow papules on the forehead that had been present since puberty. Although the lesions were asymptomatic, some had recently become tender, which led him to seek medical care. There was no history of trauma, burns, irradiation, or application of topical agents to the area or use of eyeglasses or goggles. The patient’s father had similar lesions limited to the forehead, which developed during adolescence.

On evaluation at our clinic, skin examination revealed 16 discrete, 0.3- to 1-cm, flesh-colored, yellow to blue, mobile, smooth papules, as well as flesh-colored papules with a central black punctum, on the forehead (Figure 1). Similar lesions were not present on the rest of the face; around the ears; or on the scalp, neck, chest, back, abdomen, genitalia, buttocks, palms, soles, axillae, arms, or legs. There were no nail abnormalities.

Multiple 3-, 4-, and 6-mm punch and excisional biopsies were performed to remove all 16 lesions on the forehead. Histologic examination revealed a collapsed cystic structure in the mid dermis in 10 lesions. The cysts were lined with a squamous epithelium without a granular layer but with an eosinophilic corrugated lining, and the cyst cavity contained scant homogeneous eosinophilic secretion. Mature sebaceous glands were adjacent to the outer portion of the cyst wall. These histologic findings were consistent with SCM (Figure 2).

In 3 lesions, histologic examination revealed a cystic structure lined by a few layers of stratified squamous epithelium in the mid dermis. The cyst cavity contained numerous small vellus hairs and laminated keratin. These histologic findings were consistent with EVHC (Figure 3).

In the other 3 lesions, histologic examination revealed a dilated central cystic cavity filled with laminated keratin in the mid dermis. Multiple small follicles arose from the cysts and showed differentiation toward germinative epithelium. The surrounding stroma was fibrotic and contained a patchy lymphocytic infiltrate. These histologic findings were consistent with trichofolliculomas (Figure 4).

Characteristics of SCM
Steatocystoma multiplex is an uncommon condition characterized by the formation of asymptomatic, 0.2- to 2-cm, yellow to flesh-colored, soft, mobile papules or nodules on the trunk, extremities, axillae, genitalia, and/or chest. The lesions contain a clear or opaque, oily, milky or yellow, odorless fluid and most commonly are located on the anterior aspect of the chest. The face is not a commonly involved site in this condition. Six cases of a rare facial variant of SCM have been reported,^11-16 with lesions limited to the forehead in 3 cases.^13-15

In 1937, Mount²⁰ credited Bozellini for describing the first case, though 3 cases reported in the late 1800s probably were SCM.²¹ In 1899, Pringle²² coined the term steatocystoma multiplex for this condition. It can be sporadic or have an autosomal-dominant inheritance pattern. Steatocystoma multiplex can occur at any age, though lesions develop most frequently in adolescence or young adulthood. There is no sex predilection.

Steatocystoma multiplex with pachyonychia congenita has been reported in a familial case.²³ Other findings reported in patients with SCM include ichthyosis, koilonychia, acrokeratosis verruciformis of Hopf and hypertrophic lichen planus, hidradenitis suppurativa, hypotrichosis, multiple keratoacanthomas, and rheumatoid arthritis.^12,24-26

Steatocystoma multiplex is a cyst lined by stratified squamous epithelium without a granular layer but with a thick eosinophilic cuticle. Mature sebaceous lobules are closely associated with the cyst wall. Steatocystoma multiplex arises from the sebaceous duct because the lining of the lumen is composed of undulating eosinophilic cuticle.

Characteristics of EVHCs
Eruptive vellus hair cysts, which were first described by Esterly et al,²⁷ can occur at any age but develop most frequently in adolescents or young adults. Sometimes the lesions are congenital or appear in childhood. There is no sex predilection. They can be sporadic or have an autosomal-dominant inheritance pattern.

Eruptive vellus hair cysts are asymptomatic, 1- to 2-mm, smooth, crusted, or umbilicated papules on the chest or arms and legs. Eruptive vellus hair cysts most commonly involve the anterior aspect of the chest. The lesions are flesh-colored to yellow, though they have a slate gray color in darker-skinned individuals. A rare facial variant has been reported in 2 patients of Asian descent.¹⁷

Eruptive vellus hair cysts are small cystic structures lined by a stratified squamous epithelium with a granular layer. The cyst cavity contains numerous small vellus hair shafts and laminated keratin. Eruptive vellus hair cysts originate from the infundibulum or less frequently the isthmus or infundibular-isthmic junction of the hair follicle.

Characteristics of Trichofolliculomas
Trichofolliculomas are solitary, 3- to 5-mm, flesh-colored papules that occur on the face. They are highly differentiated, benign, neoplastic proliferations of an actively trichogenic epithelium, with structural components reflecting all portions of the pilosebaceous unit. Trichofolliculomas consist of a central dilated primary follicle contiguous with the surface epidermis embedded in a fibrous stroma. Multiple small secondary follicles with varying degrees of follicular differentiation arise from the primary follicle.

Co-occurrence of Lesions
An association between SCM and EVHC has been recognized.^5-10 Steatocystoma multiplex and EVHC have similar clinical features but distinctive histologic features. They also have a similar age of onset, location/appearance of lesions, and mode of inheritance. Steatocystoma multiplex and EVHC can be distinguished by immunohistochemical techniques: SCM shows expression of keratin 10 and keratin 17, whereas EVHCs express only keratin 17.²⁸

On the morning of July 25, I scrolled through my Twitter account to see tweets flying: Psychiatrists can now defy the Goldwater Rule! Oops, wrong organization; no ,they can’t. Over the course of the day, articles appeared in Scientific American, the Los Angeles Times, Newsweek, International Business Times; and statements were issued by both the American Psychiatric Association and the American Psychoanalytic Association.

So what happened?
