THE COMPARISON

A Seborrheic dermatitis in a woman with brown-gray greasy scale as well as petaloid papules and plaques that are especially prominent in the nasolabial folds.

B Seborrheic dermatitis in a man with erythema, scale, and mild postinflammatory hypopigmentation that are especially prominent in the nasolabial folds.

C Seborrheic dermatitis in a man with erythema, faint scale, and postinflammatory hypopigmentation that are especially prominent in the nasolabial folds.

D Seborrheic dermatitis in a man with erythema and scale of the eyebrows and glabellar region.

Seborrheic dermatitis (SD) is an inflammatory condition that is thought to be part of a response to Malassezia yeast. The scalp and face are most commonly affected, particularly the nasolabial folds, eyebrows, ears, postauricular areas, and beard area. Men also may have SD on the mid upper chest in association with chest hair. In infants, the scalp and body skin folds often are affected.

Epidemiology

Seborrheic dermatitis affects patients of all ages: infants, adolescents, and adults. It is among the most common dermatologic diagnoses reported in Black patients in the United States.¹

Key clinical features in darker skin tones

• In those with darker skin tones, arcuate, polycyclic, or petaloid (flower petal–like) plaques may be present (Figure A). Also, hypopigmented patches and plaques may be prominent (Figures B and C). The classic description includes thin pink patches and plaques with white greasy scale on the face (Figure D).
• The scalp may have diffuse scale or isolated scaly plaques.

Worth noting

• In those with tightly coiled hair, there is a predisposition for dry hair and increased risk for breakage.
• Treatment plans for patients with SD often include frequent hair washing. However, in those with tightly coiled hair, the treatment plan may need to be modified due to hair texture, tendency for dryness, and washing frequency preferences. Washing the scalp at least every 1 to 2 weeks may be a preferred approach for those with tightly coiled hair at increased risk for dryness/breakage vs washing daily.² In a sample of 201 caregivers of Black girls, Rucker Wright et al3 found that washing the hair more than once per week was not correlated with a lower prevalence of SD.
• If tightly coiled hair is temporarily straightened with heat (eg, blow-dryer, flat iron), adding a liquid-based treatment such as clobetasol solution or fluocinonide solution will cause the hair to revert to its normal curl pattern.
• It is appropriate to ask patients for their vehicle preference for medications.² For example, if clobetasol is the treatment selected for the patient, the vehicle can reflect patient preference for a liquid, foam, cream, or ointment.
• Some antifungal/antiyeast shampoos may cause further hair dryness and breakage.
• Treatment may be delayed because patients often use various topical pomades and ointments to cover up the scale and help with pruritus.
• Diffuse scale of tinea capitis in school-aged children can be mistaken for SD, which leads to delayed diagnosis and treatment.
• Clinicians should become comfortable with scalp examinations in patients with tightly coiled hair. Patients with chief concerns related to their hair and scalp expect their clinicians to touch these areas. Avoid leaning in to examine the patient without touching the patient’s hair and scalp.^2,4

Seborrheic dermatitis is among the most common cutaneous disorders diagnosed in patients with skin of color.^1,5 Delay in recognition of SD in those with darker skin tones leads to delayed treatment. Seborrheic dermatitis of the face can cause notable postinflammatory pigmentation alteration. Pigmentation changes in the skin further impact quality of life.

THE COMPARISON

A A 27-year-old Hispanic woman with comedonal and inflammatory acne. Erythema is prominent around the inflammatory lesions. Note the pustule on the cheek surrounded by pink color.

B A teenaged Black boy with acne papules and pustules on the face. There are comedones, hyperpigmented macules, and pustules on the cheek.

C A teenaged Black girl with pomade acne. The patient used various hair care products, which obstructed the pilosebaceous units on the forehead.

Epidemiology

Acne is a leading dermatologic condition in individuals with skin of color in the United States.¹

Key clinical features in people with darker skin tones include:

• erythematous or hyperpigmented papules or comedones
• hyperpigmented macules and postinflammatory hyperpigmentation (PIH)
• increased risk for keloidal scars.²

Worth noting

• Patients with darker skin tones may be more concerned with the dark marks (also referred to as scars or manchas in Spanish) than the acne itself. This PIH may be viewed by patients as the major problem.
• Acne medications such as azelaic acid and some retinoids (when applied appropriately) can treat both acne and PIH.³
• Irritation from topical acne medications, including retinoid dermatitis, may lead to more PIH. Using noncomedogenic moisturizers and applying medication appropriately (ie, a pea-sized amount of topical retinoid per application) may help limit irritation.^4,5
• One type of acne seen more commonly, although not exclusively, in Black patients is pomade acne, which principally appears on the forehead and is associated with use of hair care and styling products (FIGURE C).

Health disparity highlight

Disparities in access to health care exist for those with dermatologic concerns. According to one study, African American (28.5%) and Hispanic patients (23.9%) were less likely to be seen by a dermatologist solely for the diagnosis of a dermatologic condition compared to Asian and Pacific Islander patients (36.7%) or White patients (43.2%).¹ Noting that isotretinoin is the most potent systemic therapy for severe cystic acne vulgaris, Bell et al⁶ reported that Black patients had lower odds of receiving isotretinoin compared to White patients. Hispanic patients had lower odds of receiving a topical retinoid, tretinoin, than non-Hispanic patients.⁶

THE COMPARISON

A Elbow and forearm with erythematous, well-demarcated, pink plaques with mild micaceous scale in a 42-year-old White woman.

B Elbow and forearm with violaceous, well-demarcated plaques with micaceous scale and hyperpigmented patches around the active plaques in a 58-year-old Black man.

Epidemiology

Psoriasis prevalence in the United States has been estimated at 3.7%.^1-3 If broken down by race or ethnicity, the prevalence of psoriasis varies: 2.5% to 3.7% in White adults^1-4; 1.3% to 2% in Black adults^1-4; 1.6% in Hispanics/other adults^1-3; 1% in children overall; 0.29% in White children^1,5; and 0.06% in Black children.^1,5

Key clinical features in people with darker skin tones include:

• plaques that may appear more violaceous in color instead of pink or erythematous
• higher body surface area of involvement⁴ and thicker, more scaly plaques⁶
• increased likelihood of postinflammatory hyperpigmentation (PIH).

Worth noting

Although individuals of all skin tones may experience the psychosocial impact of psoriasis, quality-of-life measures have been found to be worse in those with skin of color (SOC) compared to White patients. ^1,4 This may be due to the lingering PIH and hypopigmentation that occurs even after inflammatory plaques are treated. Of course, lack of access to care contributes to greater disease burden and more devastating psychological impact.

Health disparity highlight

Psoriasis may be underreported and underdiagnosed in individuals with SOC, as factors contributing to health care disparities may play a role, such as access to health care in general,^1,7 and access to clinicians proficient in diagnosing cutaneous diseases in SOC may be delayed.⁸

Biologic medications are used less often in Black patients than in White patients, despite biologic medications being very efficacious for treatment of psoriasis.^1,9,10

Psoriasis prevalence in the United States has been estimated at 3.7%.^1-3 If broken down by race or ethnicity, the prevalence of psoriasis varies: 2.5% to 3.7% in White adults^1-4; 1.3% to 2% in Black adults^1-4; 1.6% in Hispanics/ other adults^1-3; 1% in children overall; 0.29% in White children_^1,5; and 0.06% in Black children.^1,5

Key clinical features in people with darker skin tones include:

• plaques that may appear more violaceous in color instead of pink or erythematous
• higher body surface area of involvement4 and thicker, more scaly plaques⁶
• increased likelihood of postinflammatory hyperpigmentation (PIH).

Worth noting
Although individuals of all skin tones may experience the psychosocial impact of psoriasis, quality-of-life measures have been found to be worse in those with skin of color (SOC) compared to White patients.^1,4 This may be due to the lingering PIH and hypopigmentation that occurs even after inflammatory plaques are treated. Of course, lack of access to care contributes to greater disease burden and more devastating psychological impact.

Health disparity highlight
Psoriasis may be underreported and underdiagnosed in individuals with SOC, as factors contributing to health care disparities may play a role, such as access to health care in general,^1,7 and access to clinicians proficient in diagnosing cutaneous diseases in SOC may be delayed.⁸

Biologic medications are used less often in Black patients than in White patients, despite biologic medications being very efficacious for treatment of psoriasis.^1,9,10

THE COMPARISON

A Pink scaling plaques and erythematous erosions in the antecubital fossae of a 6-year-old White boy.

B Violaceous, hyperpigmented, nummular plaques on the back and extensor surface of the right arm of a 16-month-old Black girl.

C Atopic dermatitis and follicular prominence/accentuation on the neck of a young Black girl.

Epidemiology

People of African descent have the highest atopic dermatitis prevalence and severity.

Key clinical features in people with darker skin tones include:

• follicular prominence
• papular morphology
• prurigo nodules
• hyperpigmented, violaceous-brown or gray plaques instead of erythematous plaques
• lichenification
• treatment resistant.^1,2

Worth noting

Postinflammatory hyperpigmentation and postinflammatory hypopigmentation may be more distressing to the patient/family than the atopic dermatitis itself.

Health disparity highlight

In the United States, patients with skin of color are more likely to be hospitalized with severe atopic dermatitis, have more substantial out-of-pocket costs, be underinsured, and have an increased number of missed days of work. Limited access to outpatient health care plays a role in exacerbating this health disparity.^3,4
