Ewing's sarcoma of the foot.

Ewing's sarcoma is a rare, malignant neoplasm that is most common in children and adolescents. It is common in both the axial and appendicular skeleton but has been rarely reported in the foot. Historically, treatment has consisted of chemotherapy and radiation therapy. The roll of surgery in the management of these lesions have recently been "rediscovered" and depends on the anatomic location. The purpose of this paper is to discuss five consecutive cases of Ewing's Sarcoma of the forefoot treated with below-the-knee amputation for local tumor control. Four of the five patients also underwent some systemic chemotherapy. After comparing the various forms of therapy for this tumor, the benefits of below-the-knee amputation make it an excellent primary treatment for Ewing's sarcoma of the foot.
