Primary Ewing sarcoma of the coronoid process of mandible

Ewing sarcoma (ES) is a rare, primary malignancy of the bone that occurs mainly in childhood and early adolescence. ES usually occurs in long bones of the axial skeleton. Although uncommon in the jaws, ES at this site is most likely to occur in the posterior mandible. The outcome for patients with localised disease has improved over the decades, due to better combination chemotherapies and better methods of local control. We present the clinicopathologic features and management of a case of ES that developed in the left coronoid process of the mandible of a 31-year-old male. Chemotherapy and, later, a segmental mandibulectomy were used to achieve local control. A fibula-free flap repair was performed with good aesthetic results. This case elucidates the importance of the interdisciplinary approach required for the evaluation and treatment of this aggressive neoplasm.
