Case report: Periosteal Ewing's sarcoma: case report and literature review.
Ewing's sarcoma is a round-cell tumor that arises most often in a medullary cavity. This neoplasm is uncommon in a subperiosteal location. We report a new case of a 12-year-old boy with a periosteal Ewing's sarcoma, located in the femur, who was treated by cortical segmental resection associated with chemotherapy. Two years after surgery the patient was free of disease. In reviewing the literature of 29 cases, it seems the prognosis is better in periosteal compared with intramedullary Ewing's sarcoma.
