Diagnosing Psoriasis in Skin of Color Patients.

Diagnosing psoriasis in patients of color can pose both diagnostic and treatment challenges. It is important to keep psoriasis on the differential diagnosis with conditions such as lichen planus, tinea corporis, and subcutaneous lupus for patients of color. Biopsy can help delineate the causes and guide treatment. Although there is no documented difference in efficacy of certain treatments for psoriasis based on racial group, cultural norms, hair washing practices, health literacy, and attitudes toward certain treatment options should be elicited in all patients.
