A 23-year-old man presented with a lesion on the medial aspect of his right shin (Figure 1) that had been there for “as long as he could remember.” He stated that the lesion had grown more tender in recent years and that he wanted to have it removed. He had previously been told that the lesion was a hemangioma and had received multiple pulsed-dye and neodymium-YAG laser treatments, without significant improvement. His medical and family histories were unremarkable, and he was not currently taking any medications. He did not complain of any discharge or bleeding from the lesion.
