title: Red flags and alarm bells: an atypical lesion masquerading as a diabetic foot ulcer.
abstract: An 88-year-old male presented at a high-risk foot service with a non-healing, plantar wound on his right foot, which had the appearance of a neuropathic ulcer. On further examination, the lesion was confirmed asymmetrical in shape and atypical in appearance. It also presented with surrounding violaceous, pigmented nodules in the arch of the foot, and several small, similar nodules on the plantar surface of the contralateral foot, giving the appearance of an exophytic lesion and suggesting melanoma. Following biopsy, it was diagnosed as classic Kaposi sarcoma.
