A 10-year-old white girl presented with a 4-year history of a lesion on her chin. Over the past year, she noticed darker, longer hairs emanating from the lesion, but it was otherwise asymptomatic. Her medical history was unremarkable, and there was no pertinent family history.
On physical examination, there was an approximately 1-cm, yellowish, barely raised, ill-defined plaque on the patient's chin, with some slightly coarse, blond hairs arising from it (Figure 1). A punch biopsy specimen was obtained (Figure 2).
