Ewing sarcoma of the thoracic wall in a 54-year-old man.

Ewing tumor is the second most common bone tumor in children. Its variant, malignant small cell tumor of the thoracopulmonary region, is infrequent in children and extremely rare in adults. A multimodal treatment approach is preferred for this tumor. We describe a rare case of primitive neuroectodermal tumor/Ewing sarcoma arising from the thoracic wall in a 54-year-old man. He underwent extensive resection of the tumor followed by adjuvant chemotherapy and radiotherapy.
