# Nuclear Pleomorphism in Gastrointestinal Stromal Tumors: Insights Beyond Risk Stratification

## TL;DR

This paper discusses a rare case of a gastrointestinal stromal tumor with unusual nuclear features and how it challenges current risk assessment methods.

## Contribution

The novelty lies in presenting a GIST case with nuclear pleomorphism but no other high-grade features, questioning existing prognostic criteria.

## Key findings

- A GIST case with marked nuclear pleomorphism was identified.
- The case lacked other high-grade features typically associated with poor prognosis.
- This case suggests that nuclear pleomorphism may need reevaluation in risk stratification.

## Abstract

Gastrointestinal stromal tumors (GISTs) are very common mesenchymal neoplasms involving the gastrointestinal tract. Despite having a uniform nuclear morphology, they can show varied histological subtypes. The prognosis is based on tumor size, mitotic rate and location of the tumor. Some cases of GIST can however show marked nuclear pleomorphism. Here we report a case of GIST with marked nuclear pleomorphism without other high-grade features. This case highlights the importance of nuclear pleomorphism and its implications in the perspective of existing prognostic criteria.
