# Undifferentiated Rhabdoid Carcinoma of the Gastrointestinal Tract: A Rare and Aggressive Malignancy

## TL;DR

This paper reports a rare case of aggressive undifferentiated rhabdoid carcinoma in a healthy man's gastrointestinal tract.

## Contribution

Adds a new clinical case to the limited literature on undifferentiated rhabdoid carcinoma of the gastrointestinal tract.

## Key findings

- A 51-year-old male was diagnosed with undifferentiated rhabdoid carcinoma via histopathology and immunohistochemistry.
- The case highlights the aggressive nature and distinct features of this rare malignancy.
- Emphasizes the need for further research on the tumor's pathogenesis and treatment.

## Abstract

Undifferentiated carcinoma with rhabdoid features is an exceptionally rare malignancy within the spectrum of malignant rhabdoid tumors. We report a case of a healthy 51-year-old male presenting with an abdominal mass, ultimately diagnosed as an undifferentiated carcinoma with rhabdoid features. Histopathologic examination and immunohistochemistry revealed the distinct morphological and molecular characteristics of this aggressive tumor. This case adds to the limited published literature on this rare presentation and highlights the need for further investigation into its pathogenesis and optimal management.
