| Summary: | A gangliocytic paraganglioma is a benign tumor of the digestive system with a very low incidence. The tumor is histopathologically characterized by a triphasic pattern consisting of epithelioid, ganglion, and spindle-shaped Schwann cells. In most cases, it occurs in the second portion of the duodenum near the ampulla of Vater. We report a case of a gangliocytic paraganglioma occurring at the minor duodenal papilla (a rare location) with a concurrent adenoma of the ampulla of Vater. Both lesions were treated simultaneously using endoscopic resection. Additionally, we have presented a literature review. |
