Ewing sarcoma in a diabetic male with history of foot ulceration.

Ewing sarcoma is a rare diagnosis, with as few as 225 new cases diagnosed in North America annually, and only 3% occurring in the foot. They generally present in the second decade of life and are very infrequently found in patients older than 40 years. The diagnosis of Ewing sarcoma can be difficult, especially in older patients with diabetes and a history of ulceration, because it can have an appearance on radiography similar to that of osteomyelitis. We present a case of Ewing sarcoma of the foot in a patient with type 2 diabetes in his sixth decade of life.
