# An Exophytic Pancreatic Mass Diagnosed as Ganglioneuroma

## TL;DR

A rare case of a pancreatic ganglioneuroma tumor is diagnosed in a 47-year-old man through endoscopic ultrasound and biopsy.

## Contribution

This case report highlights the diagnosis of a rare neuroendocrine tumor in an unusual location.

## Key findings

- A ganglioneuroma was diagnosed in the pancreas of a 47-year-old man.
- The tumor was confirmed via endoscopic ultrasound and fine-needle biopsy.
- The tumor was exophytic and inseparable from the pancreatic body.

## Abstract

Ganglioneuromas are rare neuroendocrine tumors affecting around one in a million, mostly young adults. These slow-growing, well-differentiated neuroepithelial tumors originate from the neural crest and involve the sympathetic nervous system. We present an unusual case of a 47-year-old African American man with mildly elevated liver enzymes who was incidentally found to have a suspected pancreatic mass. Endoscopic ultrasound and fine-needle biopsies confirmed the diagnosis of a ganglioneuroma, inseparable and exophytic in the body of the pancreas extending into the tail.
