Tinea versicolor, or pityriasis versicolor, is a chronic, superficial fungal infection that involves the trunk and extremities with rare facial involvement. The fungus is part of normal skin flora. Finely scaling brown macules are present in fair-skinned patients, whereas scaly hypopigmented macules are often noted in dark-skinned patients.
Management and Disposition
Treatment consists of short applications of selenium sulfide lotion, topical antifungal creams, or topical ketoconazole. Resistant cases require referral and consideration of oral antifungal.
Tinea versicolor is more common in adolescents and young adults.
Clinically active areas or areas colonized with the fungus may be identified by orange fluorescence noted on the Wood lamp examination.
Normal pigmentation may take months to return.
