A gangliocytic paraganglioma (GP) is a rare benign neuroendocrine tumor. However, its origin remains unclear. It is seen mostfrequently in the second portion of the duodenum. At endoscopy, a GP characteristically appears as a pedunculated nodular submucosaltumor with erosions and surface ulcers. The histological diagnosis is usually made from endoscopic biopsies showing thepresence of epithelioid, spindle, and ganglion cells. We experienced a case of GP in a 38-year-old female who was referred becauseof a possible ampullary tumor. The endoscopic images showed a 1.5-cm, oval ampullary tumor covered with normal mucosa. Anendoscopic biopsy showed chronic duodenitis. The tumor was removed by an endoscopic papillectomy. We report a case of duodenalGP that presented as a submucosal tumor that was treated with a papillectomy and review the literature.
