Ewing's sarcoma of bone and soft tissues

Abstract

Ewing's sarcoma is a distinctive clinical and pathologic entity that may be intraosseous or of soft-tissue origin. In the facial bones, the incidence of the sarcoma is estimated at 2.5% of all Ewing's sarcoma of bone. The soft tissue of the head and neck account for 11% of extraskeletal sites of the neoplasm. Combined modality treatment has modified its high-grade malignancy.
