REPORT OF A CASE  A 10-year-old boy presented with a seven-year history of lesions on his left thigh. They were asymptomatic and were gradually increasing in size and number. Once they developed, all lesions persisted. The child was otherwise in excellent health.Physical examination revealed approximately eight slightly elevated, circinate lesions that were targetlike in appearance, with a striking collarette of scale, an inner atophic area, and a small central papule (Fig 1). Their size varied from 2 to 5 mm in diameter. A biopsy specimen was obtained from one of the lesions (Fig 2).What is your diagnosis?
