An 82-year-old white man presented with a 6-month history of a slowly enlarging growth on the vertex of his scalp. The lesion was nontender but had demonstrated a tendency to bleed spontaneously and drain pus over the past month. The patient felt well otherwise and was without systemic complaints. His medical history was significant only for a remote appendectomy and hernia repair, as well as for hypertension and arrhythmia. He had no personal history of skin cancer, although his father had had a skin cancer of an unknown type.
