A man has recurrent, hypopigmented scaly lesions on his trunk. What are these lesions and how should they be treated?
A 34-year-old man had a history of recurrent, asymptomatic, hypopigmented scaly lesions on his trunk. The hypopigmentation was more prominent in summer because the lesions failed to tan (Figure 1). Skin biopsy showed multiple spores and hyphae in the stratum corneum (Figure 2).
