# Bilateral Synchronous Testicular Cancer with Discordant Histopathology: A Case Report

## TL;DR

This case report describes a rare instance of bilateral testicular cancer with different histopathologies occurring at the same time.

## Contribution

The study presents the 57th documented case of synchronous bilateral testicular tumors with discordant histopathology.

## Key findings

- Bilateral synchronous testicular tumors with discordant pathology are extremely rare.
- This case adds to the limited literature on this unique condition.
- Such cases challenge the typical understanding of testicular tumor development.

## Abstract

Bilateral testicular tumors account for 1 to 5% of all testicular tumors. Most bilateral tumors are observed metachronously. Synchronous tumors usually present with the similar histological pattern. Bilateral synchronous testicular tumors with discordant pathology are extremely rare. Only 56 cases have been documented since Bidard first described synchronous testicular tumors with discordant pathology in 1853. To our best knowledge, this study will be the 57th case in the literature.
