A 59-year-old man visited to our institution for evaluation of positive fecal occult blood. During his hospitalization, colonoscopy was performed and revealed sanguineous mucus in the cecum. We suspected the bleeding from the upper gastrointestinal tract or small intestine, and performed gastroscopy and small intestinal barium enema. Gastroscopy showed only normal findings, but double-contrast barium enema showed a smooth-surfaced, round mass in the ileum (located about 60cm from terminal ileum) measuring about 20mm in diameter. And then we performed small intestinal endoscopy (push type) from the anal side. In the same location submucosal tumor with erosion at the top of the tumor was revealed. At the same time we tried biopsy for definitive diagnosis, but could not take tumorous component. On the enough informed consent, we performed endoscopic removal. The tumor was carefully removed by snare without bleeding or other serious complications. Pathologic examination showed submucosal mature adipose tissue with a thin fibrous capsule, which was compatible with lipoma. Small intestinal endoscopic examination is not popular yet, because of difficulty of the technique and discomfort of patients. Herein, we report a case of submucosal tumor in the small intestine successfully treated with endoscopic resection.
