Abstract: Pure sarcomas of the esophagus are exceedingly rare. We report a case of esophageal synovial sarcoma which occurred in an adolescent. The tumor was locally resected, sparing the patient esophagectomy. After postoperative radiation therapy, the patient remains alive and well without evidence of disease 28 mo after operation. The unique nature of polypoid sarcoma of the esophagus, and the potential for cure without esophagectomy, is discussed.
