    Abstract:
    A gangliocytic paraganglioma (GP) is an extremely rare neurogenic tumor nearly located in the second portion of the duodenum and has been regarded as benign. We report a case of duodenal GP in a 53-year-old man. The GP arose in the second portion of the duodenum and was shown by histological examination to consist of epithelioid cells, spindle cells, and ganglion-like cells. An endoscopic ultrasonography showed a round, well-demarcated, inhomogeneous, submucosal tumor in the 3rd-4th layer. We resected it by endoscopic mucosal resection.
