It occurs mostly in the periampullary region or ileum. The common presentations are intussusception and intestinal or biliary obstruction, depending on the location. To our knowledge, gastrointestinal (GI) bleeding from a jejunal adenomyoma has not been reported previously. We present a 74-year-old female patient who suffered intermittent tarry stool passage for 1 month. Initial upper GI endoscopy, colonoscopy and computed tomography failed to find the bleeder. A papilla-like tumor with central depression and active bleeding in the proximal jejunum was found by push enteroscopy. Exploratory laparotomy showed a submucosal nodule about 1.5 cm in size located about 20 cm distal to the Treitz ligament. Wedge resection was carried out. Pathologic examination revealed that the tumor was composed of some cystic exocrine-type ducts and bundles of smooth muscle, indicating adenomyoma. The patient was symptom-free following operation. © 2008 by Lippincott Williams & Wilkins, Inc.
