In particular, the formerly termed gangliocytic paraganglioma of the duodenum has been renamed as \u201ccomposite gangliocytoma\/neuroma and neuroendocrine tumor (CoGNET).\u201d We present an unusual CoGNET arising in the stomach, displaying distinctive histomorphologies in primary tumor and metastases.
