title: Pediatric esophageal leiomyosarcoma: a case report.
abstract: Esophageal leiomyosarcoma accounts for only 0.5% of all esophageal tumors. This rare tumor has been reported in middle-aged or elderly patients. In contrast, pediatric esophageal leiomyosarcomas have never been reported. The case described herein is the first report of an esophageal leiomyosarcoma in a pediatric patient with its own characteristics. The patient had symptoms of mild cough without dysphagia. The lesion grew rapidly and reached dimensions of 7.0 cm × 5.0 cm × 6.0 cm in a 3-month period. On computed tomography scan of the chest, the mass exhibited mild enhancement after injection of a contrast agent. More evident enhancement was found on the 3-minute delayed enhanced computed tomography scan. A Phemister operation (transthoracic esophagectomy and esophagogastrostomy) was performed on the patient. The patient did not receive adjuvant postoperative radiotherapy or chemotherapy. He has been followed for 3 years and is free of disease.
