A 12-year-old boy presented with a 1-month history of multiple, slightly pruritic, erythematous patches on his face (Figure 1). The lesions varied from 1 to 4.5 cm in diameter and were hypopigmented at the periphery. The center of each lesion was slightly infiltrated. The patches had been gradually enlarging despite treatment with topical steroids. Thermal, pain, and tactile sensations were intact at the lesion sites. There was no history of exposure to a contact allergen, and the patient was in good general health. The results of direct microscopic exami-nation for fungal elements were negative. A cutaneous punch biopsy specimen was obtained (Figure 2 and Figure 3).
