PRIMARY LEIOMYOSARCOMA OF THE ESOPHAGUS

-ANALYSIS OF 64 CASES IN THE JAPANESE LITERATURE-

Abstract

A 83-year-old famale was admitted to the Hospital with dysphagia on July 27, 1989. Barium swallow showed a well-circumscribed circular defect in the middle part of the esophagus. Esophagogastroscopy confirmed the presence of a rounded, smooth, extramucosal mass surrounded with intact mucosa. Pathological diagnosis of the removed tumor was leiomyosarcoma of the esophagus. Although leiomyosarcoma of the esophagus is a very rare neoplasm, we sequentially observed growth of the tumor. A total of 64 reported cases of primary leiomyosarcoma of the esophagus were reviewed in the Japanese literature.
