Ewing sarcoma is a rare aggressive malignant round cell tumor, primarily presenting in bone and soft tissues. This study presents two cases of this tumor in unusual locations, one in right colon which presented with intussusception and other in ovary which presented clinically as carcinoma ovary. Both the cases showed histomorphology of primitive round cell tumor with characteristic immunohistochemical profile and was confirmed on molecular analysis. We aim to highlight the importance of considering Ewing sarcoma in the differential diagnoses in these locations as they have dismal prognosis with no standard treatment modality.
