[Gastrointestinal tract leiomyomas].

The authors describe four cases of gastrointestinal tract leiomyomas. In two cases the leiomyomas were situated in the stomach, in one case in the duodenum, and in one case in the small intestine. In the stomach the diagnosis was made by endoscopy while in the duodenum and small intestine by angiography. The authors stress the value of angiography in the diagnosis of leiomyomas in the parts of the gastrointestinal tract inaccessible to endoscopic examination.
