Ampullary composite gangliocytoma/neuroma and neuroendocrine tumor (CoGNET), previously called ampullary gangliocytic paragangliomas, is a rare entity, with only few reported cases in the literature. This is a multicentric retrospective cohort study of patients treated with endoscopy or surgery for ampullary CoGNET. A literature review of ampullary CoGNET was also performed.

We present the imaging findings of a 48-year-old woman that metastasized to multiple bones with a history of duodenal gangliocytic paraganglioma. 68Ga-DOTATATE PET/CT showed multiple osteolytic bone destruction with intense uptake. Multiple bone metastases originating from duodenal gangliocytic paraganglioma confirmed histopathological results of a biopsy on the chest-back bone.

Background: Duodenal neuroendocrine tumors (NETs) are uncommon, accounting for less than 4% of all gastrointestinal neoplasms. Prognosis is related to tumoral staging and grading, as well as to the specific subtype. In this article, we retrospectively describe the clinical presentation and surgical treatment of two rare large duodenal NETs: a high-grade G3 NET and a Gangliocytic Paraganglioma (GP).

Gangliocytic paraganglioma (GP) is a rare neuroendocrine tumor primarily found in the duodenum, most commonly in the second and third sections of the duodenum. Diagnosis of GP is based on its distinctive histopathological characteristics, which include three types of tumor cells in varying proportions: i) Epithelioid, ii) spindle-like and iii) ganglion-shaped cells. The distribution of the three tumor cell components varies from case to case and a patient may be easily misdiagnosed if one of the components is predominant.

Paragangliomas (PGLs) are rare and encapsulated neuroendocrine tumors (NET), located in the adrenal gland or the extra-adrenal paraganglia. Extra-adrenal PGLs may develop a gangliocytic component with ganglion cells which are called gangliocytic paragangliomas (GPs). The most common location is the duodenum, and they appear with digestive symptoms or as an incidental finding.
