Ewings sarcoma of ilium: Resection and reconstruction with femoral head allograft.

Ewing's sarcoma is a common malignant bone tumor seen in 5-15 years age group. It often arises from diaphysis of long bones. Ewing's sarcoma arising from the ilium is very rare, and it has an unfavourable prognosis. We present a rare case report of Ewings sarcoma of ilium with no metastasis in a two and a half year old boy, who was treated with neoadjuvant chemotherapy followed by surgical excision of the tumor and reconstruction using allograft from the femoral head fixed with multiple k-wires and screw. The patient is disease free at one year follow up and the allograft has taken the shape of growing ilium and excellent functionality and gait with minimal limp. Through this report, we emphasize on the occurrence of Ewings sarcoma in unusual site and resection and reconstruction of the tumor utilizing the allograft.
