A 79-year-old woman presented with a pink nodule on the anterior left thigh that measured 10 × 12 mm. The patient reported that the lesion had been present for at least 10 years without change. It was asymptomatic other than occasional tenderness if bumped (Figure 1).
The patient's medical history was significant for a malignant melanoma removed from the left thigh in 1965 as well as several basal cell carcinomas and a squamous cell carcinoma removed from the head and neck region.
