Abstract:
A 78-year-old woman was admitted for examination and treatment of melena. Although upper and lower gastrointestinal endoscopy and abdominal computed tomography showed no bleeding lesions, oral double-balloon endoscopy revealed a long, slender polyp covered with normal mucosa and accompanied with erosions in the proximal jejunum. Surgical resection was successful. Histopathologically, the polyp was 125 mm in length and composed of edematous mucosa with dilated blood vessels. The growth was diagnosed as a rare enteric muco-submucosal elongated polyp. Her melena improved postoperatively.
