# Leiomyoma: An Exceptional Benign Tumor of the Kidney

## TL;DR

This paper presents a rare case of a benign kidney tumor called renal leiomyoma, emphasizing the importance of histological diagnosis due to its difficulty in clinical detection.

## Contribution

The paper adds a new documented case of renal leiomyoma, highlighting diagnostic challenges and the need for high suspicion in clinical practice.

## Key findings

- Renal leiomyoma is a rare benign tumor that can present as an abdominal mass and flank pain.
- Histological analysis is essential for a definitive diagnosis of renal leiomyoma.
- Clinicians should maintain a high level of suspicion for this tumor in patients with well-defined renal lesions.

## Abstract

Renal leiomyoma is a benign finding in kidney pathology. It has been documented in various organs; renal location is less frequent and has been rarely documented in the literature. We present here the case of a renal leiomyoma revealed by an abdominal mass and flank pain. The diagnosis of certainty is histological, generally on surgical specimens. Due to the challenges associated with clinically diagnosing this tumor, a high level of suspicion is warranted when a patient presents with sizable and clearly defined renal lesions.
