Gangliocytic Paraganglioma of Duodenum

Abstract EN

Gangliocytic paragangliomas are rare benign tumors which are usually encountered in the second portion of the duodenum.

Histogenesis of these tumors is incompletely understood.

Patients usually present with upper gastrointestinal bleeding.

The endoscopic features of gangliocytic paraganglioma do not differ from those of other submucosal tumors.

Therefore, they can be diagnosed histologically by the presence of epithelioid, spindle, and ganglion cells, which is similar to that observed for paraganglioma.

We herein report a case of gangliocytic paraganglioma due to the rarity of the lesion and the characteristic histopathologic findings.
