Abstract
Review of current data from the Intergroup Ewing Sarcoma Study (IESS) shows that Ewing sarcoma is rare in bones of the hands and feet. The 12 patients from the IESS protocols with hand or foot Ewing sarcoma are comparable to those already reported in the literature. With the exception of lesions in the calcaneus, the prognosis for disease-free survival is excellent. The radiographic features of hand and foot Ewing sarcoma are generally those of classic Ewing sarcoma: permeation, soft-tissue mass, and, often, associated sclerotic reaction. However, with the exception of sclerosis, features suggesting bone reaction and slow tumor growth in these patients were distinctly uncommon compared with Ewing sarcoma in general. Those radiographic features suggesting aggressive behavior were slightly more common than in the general Ewing population. Even so, neither the radiographic appearance nor the greatest dimension of the radiographic lesion can be shown to contribute significantly to prognostication in these pat...
