A 50-year-old white woman from a rural area presented with a 10-year history of a slowly increasing mass on her earlobe. She had previously consulted a general practioner, who diagnosed hemangioma, and the lesion was left untreated. Dermatologic examination revealed that the left earlobe was enlarged because of a soft erythematous pendulous mass that extended the lower lateral part of the concha and auriculae (Figure 1). Reddish brown nodules were observed on the surface of the helix and antitragus, which became pale brownish yellow on diascopic pressure. A white atrophic scar area and a superficial ulceration were also noted. There was no evidence of regional lymphadenopathy. The patient was otherwise healthy, and there was no history of previous trauma or insect bite at the lesional site. She had a history of severe cough when she was young, but she did not recall the treatment she had received at that time. A complete blood cell count, a routine serum chemistry profile, and the findings of urinalysis were normal. A 4-mm punch biopsy specimen was obtained from a nodule (Figure 2).
