 A man in his 40s was admitted to our hospital with anemia and melena. Contrast-enhanced computed tomography showed a heterogeneous enhanced structure with calcification in the jejunum. Small bowel series and transoral single-balloon enteroscopy led to the detection of a protruding tumor characterized with an oval, smooth surface covered with normal epithelium and central depression without erosion and ulceration. The lesion was diagnosed as a GIST(gastrointestinal stromal tumor)by pathological examination after laparoscopic resection was performed. Unlike our case, small bowel GIST complicated bleeding is usually accompanied by mucosal injury. The depressed region may be formed due to an imbalance of proliferation that occurred between the marginal and central areas of the tumor. Therefore, the center of the lesion may be relatively depressed.
