Massive intestinal bleeding in hemangiomatosis of the duodenum.

A 33-year-old male was admitted to Takano Hospital with fainting spell and diaphoresis due to massive terry stool. He had been working and in good health until 2 days before admission. Urgent duodenal endoscopy disclosed hemorrhage from an angiomatous lesion of the duodenum. A duodenal resection with duodenojejunostomy was performed. Pathologic examination revealed a cavernous hemangiomatosis of the duodenum. The patient had a good postoperative course. Hemangioma of the intestinal tract is rare. To our knowledge, the present case is the first case in which urgent endoscopy has succeeded in establishing the preoperative diagnosis of this lesion and ascertaining the bleeding point.
