A 83-year-old man presented with a 2-month history of numerous dome-shaped papules on his right arm. His family history and his medical history were noncontributory.
Physical examination showed firm, partly confluent, 2-mm to 1.5-cm red papules and nodules in a sleevelike arrangement with a smooth, shiny surface and well-defined margins (Figure 1). The findings of the rest of the physical examination were unremarkable. Laboratory tests showed an erythrocyte sedimentation rate of 34.50 mm in the first hour (reference range, 4-15 mm/h).
