Dermatoscopic pattern of a cylindroma

A 65-year-old man presented with an asymptomatic lesion on the left parietal scalp of 6 months’ duration. Three years prior, a cylindroma on the same area was excised by a general surgeon. Physical examination revealed a solitary 6 mm salmon-pink, firm, dome-shaped papule on the left parietal scalp (Figure 1). Dermatoscopic evaluation showed arborizing telangiectasia and several scattered white globules on a white to salmon pink background (Figure 2). The lesion was excised for pathologic evaluation. Histologic evaluation shows multiple irregular lobules in a jigsaw-mosaic pattern diagnostic of cylindroma (Figures 3 and 4).
