A Case Report of an Unusually Large Heterotopic Pancreas

TL;DR

This case report describes a rare instance of a large heterotopic pancreas in a patient's stomach, leading to persistent vomiting and requiring surgical removal.

Contribution

The novelty lies in documenting an unusually large and well-differentiated type I heterotopic pancreas in a clinical case.

Findings

A 57-year-old man had a uniquely large type I HP in the lesser curvature of the stomach.

Symptoms resolved after surgical resection of the heterotopic pancreas.

Histopathological examination confirmed the diagnosis of HP.

Abstract

Heterotopic pancreas (HP) is the presence of pancreatic tissue outside of its normal anatomical position without vascular continuity from the main pancreas. HP is most commonly found within the gastrointestinal tract, particularly the stomach through the jejunum. This report shares the case of a 57-year-old man who presented with persistent vomiting despite medical therapy. Given the nonspecific and broad differential diagnosis, a histopathological examination was warranted for a definitive diagnosis that showed a uniquely large and well-differentiated type I HP in the lesser curvature of the stomach. Resection was completed which was followed with resolution of symptoms.
