PRIMARY EWINGS-SARCOMA OF THE MAXILLA, A RARE AND CURABLE LOCALIZATION - REPORT OF 2 NEW CASES, SUCCESSFULLY TREATED BY RADIOTHERAPY AND SYSTEMIC CHEMOTHERAPY

Primary maxillary localization of Ewing's sarcoma is unusual. Involvem ent of facial bones is characterized by clinical and radiological feat ures distinct from those commonly observed in other sites. Because of the above peculiarities a delay in diagnosis and thus in starting trea tment is very probable in such cases. We report here two new cases of Ewing's sarcoma localized to facial bones, successfully treated by loc al high dosage radiotherapy and systemic chemotherapy. Our experience suggests that, especially for particular sites not suitable to radical surgery, radiation therapy can represent an effective tool to achieve local control of the tumor.
