# Renal tumors with different histological types occurring in the same kidney: A case report

## TL;DR

A rare case of two different kidney tumors in the same kidney was found in an 84-year-old man, who remained cancer-free for three years after surgery.

## Contribution

This case report highlights the coexistence of chromophobe and clear cell renal cell carcinomas in a single kidney, a rare clinical scenario.

## Key findings

- A patient had chromophobe and clear cell renal cell carcinomas in the same kidney.
- The patient remained recurrence-free for three years after radical nephrectomy.
- No decline in renal function was observed during the follow-up period.

## Abstract

We report on one rare clinical case where renal tumors of different histological types occurred simultaneously. An 84-year-old male with two right renal tumors underwent radical nephrectomy. Pathology revealed chromophobe renal cell carcinoma (ChRCC) and clear cell renal cell carcinoma (ccRCC). He had a 3-year recurrence-free survival without renal function decline.
