We report a 82-year-old female with liver chirrhosis who presented melena and anemia. Initial upper GI endoscopy, colonoscopy and computed tomography failed to find the bleeder. Double balloon endoscopy revealed sub mucosal nodule about 60mm in diameter located at proximal jejunum. Surgical resection was carried out. Pathologic examination indicated that the tumor was adenomyomatous hamartoma. The patient was symptom-free after the operation.
