title: Transoral endoscopic resection of esophageal liposarcoma.
abstract: A 63-year-old man presented with a 1-month history of dysphagia. Endoscopy showed the patient had a mass in the cervical esophagus. Multiple biopsy specimens were taken, which were inconclusive for a diagnosis. A positron-emission tomography scan showed a hypermetabolic lesion. A transoral endoscopic approach was used to resect the tumor. Final histologic examination revealed a completely resected low-grade liposarcoma.
