A 45-year-old man presented for evaluation of a slowly growing, ill-defined area of alopecia localized on the lower part of his left leg. The lesion had been present for 2 years. Physical examination revealed a 5 × 10-cm asymptomatic area of alopecia studded with follicular keratotic papules (Figure 1). There was no lymphadenopathy, and the results of the rest of the physical examination were normal. A biopsy was performed (Figure 2).
