Ewing's sarcoma is a high-grade neuroectodermal primary bone tumor. This is the second primary bone tumor in children afterosteosarcoma and represents 4 to10% of cases. It can occur in all skeletal bones. However, the location at the facial bones is uncommon (1to2%) and extremely rare at the sphenoid sinus. We report the clinical results of a rare case of Ewing's sarcoma of the sphenoid with intraorbitaland intracranial extension.

Background: Several studies have shown that the intensity of treatment in Ewing sarcoma has an impact on outcome. The present trial tested the non-inferiority of intensive, shorter, induction chemotherapy (25 weeks total treatment time) compared to the standard treatment (37 weeks) in non-metastatic Ewing sarcoma (ES) at onset.
Procedure: This national, multicenter, parallel, randomized, controlled, open-label, non-inferiority, phase III trial was conducted in 14 specialized hospitals in Italy.
