Ewing's sarcoma is a malignant tumor belonging to the group of small round cells tumors. Histologically similar to soft tissue neoplasms originally described as primitive neuro-ectodermal tumors (PNET), in the WHO classification, Ewing's sarcoma and PNET are labeled together under the rubric of EWS/PNET. Rarely located in the nasal cavity and the para-nasal sinuses, we report three cases of Ewing's sarcoma of maxillary bone and sinus. Our patients, 2 males and one female, were aged 20, 16 and 13years respectively. The chief complaint was a painful face swelling. The diagnosis was retained on histologic and immuno-histochemical results. In two cases, surgery was performed as primary treatment modality followed by chemo-radiotherapy, which was the only therapeutic modality in the remaining case. After a follow-up of 2, 3 and 8years (for each patient), we did not report local or distant failures.
