REPORT OF A CASE
A 35-year-old man was referred for dermatologic consultation after a routine physical examination revealed numerous papular lesions. He had first noticed the papules approximately 5 or 6 years earlier. They were completely asymptomatic and had not significantly changed with time. The lesions did not tan, and their appearance was not altered with 1 year's use of tretinoin prior to the referral. There was no family history of similar lesions. Examination revealed many white, 2- to 3-mm papules, predominantly on his forehead, face, and upper torso (Figs 1 through 3). Many of the papules had hairs at their periphery. Shave biopsy specimens of several lesions were obtained.The shave biopsy specimen showed a typical papular lesion composed of loose connective tissue with blood vessels. The epidermis was relatively flattened and an elongated rete ridge was seen at the margin (Fig 4).What is your diagnosis?
