A 65-year-old man with a chief complaint of black stool visited our hospital. Upper GI endoscopy revealed a submucosal tumor located in the intraduodenal angle on the opposite of the pancreas. Abdominal CT showed a 29 mm solid mass located outside of duodenum. Laparoscopic partial duodenectomy was performed for tumor resection. The patient was discharged on the 14th post-operative day without complications. Immunohistological staining showed positive for c-kit, positive for CD34. Histopathological diagnosis was duodenal gastrointestinal stromal tumor(GIST) with low risk grade of Fletcher's classification. The patient has no recurrence without adjuvant chemotherapy for 30 months. Laparoscopic surgery suggested useful for duodenal GIST.
