title: Primary orbital Ewing's sarcoma presenting with local recurrence to maxillary sinus shortly after tumor resection.
abstract: Ewing's sarcoma (ES) is a malignant, small-round-cell neoplasm that normally affects the long bones of the limbs or the pelvis. Primary orbital ES of the skull has been considered extremely rare. We describe the case of a 19-year-old female patient with primary ES originating from the inferior orbital rime and, shortly after tumor resection, local recurrence to the maxillary sinus.
