A CASE OF DUODENAL LIPOMA RESPONSIBLE FOR THE MELENA

Abstract

A 66 year-old woman was admitted to our hospital because of progressive quadriplegia and anemia. Upper GI endoscopy revealed a pedunculated submucosal tumor with ulceration in the duodenal bulb. We supposed that the cause of melena was due to bleeding from the tumor because no lesions were demonstrated on small-intestinal radiography. Endoscopic ultrasono-graphy showed an echogenic mass, supporting the diagnosis of a duodenal lipoma which was treated by endoscopic polypectomy after obtaining an informed consent. It was measured 13× 12mm in size and the pathological diagnosis was also the same as lipoma. Thereafter, melena and anemia disappeared with complete remission.
