A 9-year-old boy of Brazilian descent presented with a 9-month history of a persistent, asymptomatic skin eruption that had first appeared during the summer. Physical examination disclosed multiple bilateral and symmetrically distributed monomorphic annular plaques characterized by an atrophic hyperpigmented (brownish) center surrounded by a slightly elevated, scaly, hypopigmented or erythematous border. The lesions were located on the face (forehead, nose, perioral region), extensor surface of the forearms, and dorsum of the hands (Figures 1 and 2). There was no mucosa or nail involvement. The boy was otherwise healthy, with no history of drug exposure, atopic dermatitis, or family skin diseases. A biopsy specimen from one of the hand lesions was taken for histologic examination (Figures 3 and 4).
