An 83-year-old white woman with a history of leg venous ulcers and benign IgG gammopathy presented with bilateral and symmetrical inguinal 2- to 4-mm pigmented papules (Figure 1). There was no pruritus, and skin lesions were not aggravated by rubbing or scratching. There was no lymphadenopathy or hepatosplenomegaly. The blood cell count and the hepatic and renal functions were normal, as were the findings of bone marrow analysis. A skin biopsy specimen was obtained (Figure 2 and Figure 3), and a Giemsa stain was performed (Figure 4).
