A 20-year-old obese Hispanic man presented with a 6-month history ofan asymptomatic, papular eruption that had begun on his shoulders and hadslowly spread across his chest, back, buttocks, and arms. His medical historywas significant for hypertension and for diabetes mellitus of approximately1 year's duration. His family history was noncontributory.
Physical examination revealed hundreds of small (1- to 7-mm-diameter),yellowish papules on the upper part of his arms, chest, and back. Most ofthese lesions appeared to be umbilicated and were surrounded by erythematoushalos (Figure 1 and Figure 2). The patient also had several lesions that were excoriated.He denied any local or systemic symptoms. Punch biopsy specimens were obtainedfrom 2 lesions on his elbow and upper arm area (Figure 3 and Figure 4).
