 A case of gangliocytic paraganglioma of the duodenum was reported. The patient was a 64-year-old woman. An upper gastrointestinal series of tests and endoscopy revealed a polypoid tumor in the second portion of the duodenum. Endoscopic ultrasonography showed the tumor with inhomogeneous echotexture in the submucosa. Endoscopic polypectomy was performed. Histopathologically, epithelioid cells were arranged in nests and ganglion-like cells were scattered and surrounded by spindle cells. Immunohistochemical staining for neuron specific enolase, S-100 and chromogranin showed positive results. Thus, the tumor was diagnosed as a gangliocytic paraganglioma. This disease is so rare that only 23 cases have been reported in Japan so far.
