An otherwise healthy 24-year-old man presented with an asymptomatic lesion on the left side of the middle of his back that a friend had brought to his attention 4 weeks earlier. The lesion was an ovoid, purplish black, frambesiform nodule, measuring 1 cm in diameter, with a 4-mm surrounding rim of ecchymosis (Figure 1). The innermost aspect of the ecchymotic halo was lighter than the outermost portion. The lesion did not blanch with diascopy. The results of the rest of the physical examination were unremarkable.
