 A 63-year-old man with massive melena was admitted. Small intestinal endoscopy revealed a pedunculated submucosal tumor in the 4th portion of the duodenum. Endoscopic ultrasonography revealed an isoechoic tumor located in the submucosa. Endoscopic polypectomy assisted by laparoscopy was performed. Histologically, the tumor was diagnosed as a gangliocytic paraganglioma, but it was difficult to differentiate from carcinoid tumor. Submucosal tumors of the duodenum should be differentiated from gangliocytic paraganglioma.
