We report a 48-year-old man with a 3-month history of ulceration on his right inner thigh. The lesion began as a firm, painless, indurated nodule following a trip to rural Victoria, Australia. Over the following weeks, the lesion evolved into a painless, necrotic ulcer that continued to increase in size over the subsequent months. At the time of presentation, clinical examination revealed a 3 × 2 cm violaceous, indurated ulcer with undermined edges and a necrotic base.
