An 82-year-old man presented with an 8-month history of asymptomatic lesions near the site of a previous below-the-knee amputation. He reported that the original lesions had enlarged and that newer, smaller lesions had developed during the 8-month period. He also stated that his prosthesis did not irritate the lesions and that the amputation had been performed nearly 30 years earlier for the treatment of a “sarcoma,” although he could not remember the details of the original diagnosis. His medical history was unremarkable.
