# Small Bowel Gastrointestinal Stromal Tumor (GIST) Presenting With Massive Gastrointestinal Bleeding

## TL;DR

A rare case of a small bowel GIST caused severe bleeding, emphasizing the need for urgent surgery.

## Contribution

Highlights the clinical urgency of diagnosing and surgically treating massive bleeding from small bowel GISTs.

## Key findings

- A young healthy man presented with syncopal episode and bloody diarrhea due to a small bowel GIST.
- Massive gastrointestinal bleeding from GISTs requires immediate surgical intervention to prevent life-threatening complications.

## Abstract

Gastrointestinal stromal tumors (GISTs) of mesenchymal origin may affect any part of the gastrointestinal tract. These tumors are incidentally discovered during endoscopic or radiological investigations, as the clinical manifestations are usually nonspecific. Factors determining prognosis include size, location, number of mitotic figures per high-power field, and tumor rupture. We present the case of an otherwise healthy young man who was brought to our emergency room following a syncopal episode and developed bloody diarrhea en route. The aim is to highlight the need for emergency surgery once diagnosed, as the bleeding is usually massive, recurrent, and life-threatening.
