 A 51-year-old man was adimitted to our hospital because of a duodenal submucosal tumor found during a regular medical checkup. Upper gastrointestinal endoscopy revealed a 30-mm sized submucosal tumor located just below the major vater of the duodenal 2nd portion. Endoscopic ultrasonography showed the hypoechoic tumor located in the submucosa with cystic lesions. No metastatic lesion was delineated by an abdominal CT scan. Endoscopic polypectomy using a loop snare was performed without any complications. The tumor was histologically diagnosed as a gangliocytic paraganglioma. It is clinically important to recognize that a submucosal tumor may be a gangliocytic paraganglioma if the submucosal tumor is located near the ampullary region and is visualized with cystic compornents by EUS. Because gangliocytic paraganglioma is generally a benign tumor, it is important that the tumor should be resected in a less invasive fashion such as endoscopic resection.
