BACKGROUND An 87-yeаr-оld Filipinо mаn presents tо the emergency depаrtment with a protuberant mass on his right heel that he first noticed 2 months ago. Since then, the mass has enlarged and has become increasingly uncomfortable with walking. The mass is otherwise painless, but it frequently oozes blood after walks or minor trauma. The patient denies having previous local trauma or walking outdoors in bare feet. He otherwise feels well, without fever, rashes, leg swelling, systemic symptoms, or other unusual lesions. On physical examination the patient is a well-appearing, elderly man in no apparent distress who is wearing a blood-soaked bandage over his right heel. On the plantar aspect of his heel is a 2-cm, exophytic, nontender mass with areas of central necrosis. The lesion is raised, with ill-defined borders and areas of uneven brown-black discoloration and erythema. He has no palpable inguinal adenopathy. Hint : Most of these lesions occur in sun-exposed areas, but a few occur in nonexposed areas. Question: What is the diagnosis?
