Dermatology & Skin of Color: Complex Cases

Diagnostic Dilemmas in Skin of Color: Expert Insights from 2025 SDPA Conference

Washington, DC – At the 2025 Society Of Dermatology Physician Assistants (SDPA) Annual Summer Dermatology Conference, dermatologists addressed critical issues in correctly diagnosing skin conditions in people of color. A leading expert, Dr. Ginette Okoye, dermatology chair at Howard University College Of Medicine, presented a session focused on the unique complexities involved in diagnosing dermatologic conditions in richly-pigmented skin. Her session, “Diagnostic Dilemmas: Complex Cases in Skin of Color,” highlighted how subtle visual cues can often be missed or misinterpreted, leading to potential misdiagnoses.

Navigating Diagnostic Challenges in Dermatology

Dr. Okoye used real-world case studies to guide attendees through the diagnostic challenges associated with inflammatory, pigmentary, infectious, and autoimmune diseases, all of which can mimic each other in individuals with skin of color. Attendees learned to identify key differences in how common and uncommon dermatologic conditions manifest in darker skin tones. The session underscored how standard diagnostic assumptions can sometiems lead to delayed or incorrect diagnoses.

Did you know that acne can present with post-inflammatory hyperpigmentation in skin of color, often requiring different treatment approaches compared to lighter skin tones? This illustrates the importance of specialized knowledge in dermatology.

Case Study: Juvenile Dermatomyositis

One compelling case involved an 11-year-old boy with a six-month history of discoloration on his face, especially his eyelids, and a rash on the back of his hands initially diagnosed as eczema.

Despite treatment with topical steroids, the rash persisted, and the facial hyperpigmentation seemed to be spreading. The boy had a history of asthma and displayed significant muscle weakness.

Dr. Okoye detailed her diagnostic process: “Before I knew about the muscle weakness, looking at him, I thought maybe some seborrheic dermatitis… I thought about dermatomyositis briefly, because whenever I see something going on on the eyelids and on the knuckles, I always think of dermatomyositis… I really honed in on dermatomyositis.”

Ultimately, the child was diagnosed with juvenile dermatomyositis, highlighting the importance of recognizing subtle signs such as muscle weakness.

Understanding Proximal Muscle Weakness

In dermatomyositis, muscle weakness typically affects the proximal muscles, including the shoulder girdle, thighs, and quadriceps. A swift test for proximal muscle weakness involves asking the patient to stand from a sitting position without assistance.

“early detection is key,” says Dr. Anya Patel, a dermatologist at the Skin Health Institute in Miami, Florida. “Regular screenings for muscle weakness can significantly impact the course of treatment.”

The Elevated Risk of Cancer in Dermatomyositis patients

Dr. Okoye emphasized that adults with dermatomyositis,especially those over 45,face a significantly higher risk of cancer-four to five times greater than those without the condition. While the cancer risk is lower in children, it remains elevated for about five years following diagnosis, necessitating regular screenings.

pro Tip: Implement annual screenings for cancer in dermatomyositis patients for at least five years post-diagnosis to ensure early detection and intervention.

Improving Diagnostic Accuracy: A Multifaceted Approach

Dr. Okoye’s session underscored the necessity of pattern recognition, careful clinical assessment, and strategic use of biopsies and lab tests to reach accurate diagnoses. She also addressed common diagnostic errors that disproportionately affect patients with skin of color and offered practical strategies to mitigate these pitfalls.

The Imperative of Culturally Competent Interaction

beyond clinical acumen, the session highlighted the crucial role of culturally competent communication in building trust and improving diagnostic accuracy within diverse patient populations. Attendees were encouraged to adopt an inclusive diagnostic approach, refining their clinical judgment by integrating visual nuances and patient-centered strategies.

Evergreen Insights on Dermatology in Skin of Color

Diagnosing skin conditions in individuals with skin of color requires a nuanced approach. Here are some evergreen insights for healthcare providers:

• Hyperpigmentation and Hypopigmentation: Inflammatory skin conditions often lead to post-inflammatory hyperpigmentation or hypopigmentation, which can obscure the original condition. Consider this when assessing treatment efficacy.
• Keloid Formation: Individuals with skin of color are more prone to keloid formation after skin injuries or procedures. Employ preventative strategies, such as pressure dressings or silicone gel sheeting.
• Cultural Sensitivity: Always consider cultural practices and beliefs that may influence skincare routines or perceptions of skin health.

Condition	Presentation Differences in Skin of Color	Diagnostic Considerations
Eczema	May present with follicular accentuation or papular eruptions.	Assess for post-inflammatory pigment changes; consider biopsy if atypical.
Psoriasis	Plaques may appear darker and less erythematous.	Look for silvery scale and nail involvement; be aware of potential misdiagnosis as lichen planus.
Lupus Erythematosus	Discoid lupus may cause more pronounced pigment alteration.	Evaluate for systemic symptoms and conduct appropriate serological testing.

Dermatology & Skin of Color: Unraveling Complex Cases

Dermatology for individuals with skin of color presents unique challenges and requires a deep understanding of pigmentary variations, cultural factors, and specific disease presentations.Prosperous treatment hinges on accurate diagnosis and culturally competent care. This article delves into the complexities of dermatology in skin of color, providing valuable insights for both patients and healthcare professionals.

The Unique Characteristics of Skin of Color

Skin of color encompasses a wide range of ethnicities and skin tones, including individuals of African, Asian, hispanic, and Native American descent. Understanding the specific physiological and structural differences in these skin types is crucial for effective diagnosis and treatment. The primary factor impacting these differences is the amount and distribution of melanin, the pigment responsible for skin and hair color.

Melanin’s Role in Skin Health

Higher melanin levels provide increased protection against ultraviolet (UV) radiation, offering a natural barrier against sun damage and skin cancer. Though, this increased melanin also influences the appearance of various dermatological conditions and can lead to unique challenges. The distribution of melanin can also influence the manifestation of scarring and pigmentary disorders, which requires specific consideration in treatment.

Common Dermatological Conditions in Skin of Color

Certain dermatological conditions are more prevalent or present differently in those with skin of color. clinicians must be aware of this and tailor their approach to diagnostics and treatment.

• Hyperpigmentation: Conditions like post-inflammatory hyperpigmentation (PIH), melasma, and solar lentigines (sunspots) are frequently encountered. PIH, a darkening of the skin after inflammation caused by acne, eczema, or injury, is especially common and can be triggered by seemingly minor skin injuries.
• Hypopigmentation: Vitiligo and other conditions leading to loss of pigmentation require prompt and specialized management.
• Acne and Scarring: Acne presents differently, ofen leading to more severe inflammation and a higher risk of scarring, including keloids and hypertrophic scars. this demands proactive treatment to minimize long-term effects.
• Hair and Scalp Disorders: Traction alopecia, central centrifugal cicatricial alopecia (CCCA), and other hair loss conditions are common and require specific diagnostic approaches and treatment regimens.

Table: Differential Diagnosis

here’s a basic table to illustrate how a few key conditions in skin of color may differ in their presentation and needs.

Condition	Common presentation in Skin of Color	Key Considerations
Post-inflammatory Hyperpigmentation (PIH)	Darkened spots after acne, eczema, or injury	Early intervention to prevent worsening and permanent pigment change
Keloids	Raised, thickened scars that extend beyond the original wound	Prevention methods and proper scar treatment are key
Melasma	brown or gray-brown patches on the face, often symmetrical	Sun protection is essential and treatment is challenging and requires multi-pronged approaches

Diagnostic Challenges and Strategies

Diagnosing dermatological conditions in skin of color can present challenges due to the varying presentation of diseases.The appearance of lesions can be subtle, making visual diagnosis difficult.Further, it’s important to be aware of cultural and environmental considerations regarding the patient’s lifestyle.

Leveraging Diagnostic Tools

To ensure proper diagnosis, dermatologists will frequently use the following. Remember that you shouldn’t try to perform these procedures on your own; visit a certified dermatologist.

• Dermoscopy: A non-invasive technique that uses a magnifying lens and specialized lighting to visualize subsurface skin structures, helping to differentiate between various skin lesions.
• Wood’s Lamp Examination: this technique uses ultraviolet light to highlight pigmentary changes.
• Skin Biopsy: While a biopsy can be critical for accurate diagnosis, it carries a higher risk of scarring and PIH in patients with skin of color, and must be managed appropriately.

Effective Treatment Strategies

Treatment strategies for dermatological conditions in skin of color must be tailored to the individual’s skin type, condition severity, and long-term goals. The dermatologist will consider specific clinical factors and patient history when deciding on treatment.

Therapeutic Options

Here are some of the standard therapies used for several common skin related conditions:

• Topical Treatments: Certain topical creams, such as those with retinoids, hydroquinone (used with caution due to risks of rebound hyperpigmentation), corticosteroids, and azelaic acid, can improve skin health.
• Chemical Peels: Superficial to medium-depth chemical peels can have positive effects on hyperpigmentation, acne scarring, and overall skin tone when used carefully.
• Laser and Light Therapies: Lasers and light-based treatments, such as pulsed dye lasers and fractional lasers, can address acne, hyperpigmentation, and excessive hair growth. careful selection of laser parameters and techniques are essential to avoid further pigmentary complications.
• Oral Medications: Oral medications like isotretinoin for severe acne and oral corticosteroids for inflammatory conditions may also be necessary.

Practical Tips for Patients

• Sun Protection is Paramount: Daily use of broad-spectrum sunscreen with an SPF of 30 or higher, and wearing protective clothing, are critical to prevent and manage hyperpigmentation, premature aging, and skin cancer.
• Gentle Skincare Routines: Use mild cleansers and moisturizers, and avoid harsh scrubs or exfoliants that can trigger inflammation and PIH.
• Consultation with a Dermatologist: Early and accurate diagnosis is critical; seek professional consultation for evaluation and treatment.
• Avoidance of Aggravating Factors: Minimize picking or scratching at skin lesions, and avoid procedures that can worsen your condition.
