Abstract
A 55-year-old man consulted a local clinic complaining of dysphagia, and was referred to our hospital under a diagnosis of submucosal tumor of the esophagus. A barium radiogram of the esophagus demonstrated a giant tumor measuring 20 cm pedunculated from the cervical esophagus and reaching the lower thoracic esophagus. Endoscopy revealed the surface of the tumor to be covered with normal esophageal epithelium and positive cushion sign. Thoracic CT demonstrated that a large mass occupied a dilated esophageal lumen and was heterogeneously composed of enhancing part and non-enhancing fatty part. A giant submucosal tumor developing from the cervical esophagus was diagnosed, and operation was performed. The entire tumor was removed safely through cervical esophagotomy under direct visualization. The macroscopic view of the resected specimen revealed an elastic soft tumor measuring 20×6 cm covered with normal esophageal mucosa. Pathologically, it was diagnosed as a benign fibrovascular polyp composed of various amounts of adipose tissue, fibrous tissue and vascular structures. The patient has been in good health without any evidence of recurrence 2 years after operation.
