Arteriovenous malformation of the esophagus disguised as a leiomyoma.

Hemangiomas, benign tumors of vascular origin, compromise less than 3% of all nonmalignant esophageal neoplasms. Because of their infrequent occurrence, such vascular tumors may be mistaken for more common benign tumors of the esophagus. We report the successful surgical management of an esophageal arteriovenous malformation presenting with clinical, radiographic, and endoscopic features resembling those of a leiomyoma.
