A 72-year-old white man presented for evaluation of multiple slow-growing papules in the right popliteal fossa. These asymptomatic papules had been present for several years.
The findings of the physical examination were notable for 4 variably sized, reddish-brown, firm papules, the largest measuring 6 mm and the smallest 2 mm, in the right popliteal fossa (Figure 1 [arrows identify smaller papules on the medial surface]). The papules were smooth and dome shaped, and the largest one had a peripheral collarette of fine white scale and a moist-appearing surface. The results of the rest of the physical examination were significant only for diffuse, mild xerosis.
