A 61-year-old man presents with a painless plaque on the right side of his scrotum; the plaque first appeared 1.5 years ago and has been slowly enlarging since. The patient reports experiencing no fevers or chills since the plaque developed. On examination the bright reddish, irregularly shaped plaque measures 4.0 × 1.5 cm and has erosions on the surface (Figure 1). The physical examination is otherwise unremarkable. Results of complete blood cell count and differential are normal.
