A man in his 30s presented with a 3-month history of gradual growth of a pruriginous, reddish nodule on the left ear. He had no relevant medical history. On medical examination, a reddish, smooth, superficial nodule with small dimples and a soft consistency that measured approximately 1.5 cm in diameter was seen on the left earlobe (Figure, A). It was not painful to the touch. The patient reported no history of lesions or foreign bodies at this location. A biopsy specimen was obtained for histopathologic analysis (Figure, B and C).
