# Epithelial Predominant Wilms Tumor in an Adult Patient: Case Report and Literature Review

## TL;DR

This paper reports a rare case of epithelial predominant Wilms tumor in an adult and reviews related literature.

## Contribution

The novelty lies in presenting a rare adult case of epithelial predominant Wilms tumor and discussing its distinct characteristics and outcomes.

## Key findings

- Epithelial predominant Wilms tumor may have a distinct origin and better outcomes compared to other subtypes.
- The case highlights the diagnostic challenges in adult Wilms tumor patients.
- Literature review suggests the need for tailored treatment approaches in adult cases.

## Abstract

Although rare in adults, Wilms tumor is the most common pediatric renal tumor. Treatment typically involves radical nephrectomy followed by adjuvant chemotherapy or radiation, although outcomes differ between children and adults which may be due to challenges in accurately diagnosing these patients. In this article, we present a case report of an adult patient with Jeune syndrome and multiple urologic abnormalities who underwent radical nephrectomy for a large renal mass and was subsequently diagnosed with an epithelial predominant Wilms tumor. Epithelial predominant Wilms tumor may have distinct origins from other Wilms tumor histological subtypes and may incur better outcomes. Herein, we discuss the literature surrounding this rare entity as well as the anticipated treatment course.
