[Schwannoma of duodenum: a case report].

We report a case of malignant schwannoma of the duodenum, a neural tumor, which rarely occurs in the gastroduodenal tract. The diagnosis was done after an hemorragic episode of the upper gastrointestinal tract and the treatment done was a local resection. Two years later the patient had no symptoms, but the control endoscopy showed a recurrence of the tumor in the second portion of the duodenum and the patient was submitted to a gastroduodenopancreatectomy. The authors reported the case and make a revision on intestinal schwannomas.
