Abstract:
Gangliocytic paraganglioma (GP) is a rare tumor that predominantly occurs in the duodenum. We report a case of GP in a man in his 70s. The specimen obtained by EUS-FNAC revealed three cell populations: epithelioid cells, spindle cells, and ganglion-like cells, similar to those seen in NET and paraganglioma. While NET and GIST are considered differential diagnoses, the cytological features of GP have been reported, but the number of such reports is limited. In this paper, we report a case of GP with a comparison of cytological and histological findings.
