# Rare Neuroendocrine Tumor of the Bladder: A Case Report

## TL;DR

A rare case of a bladder tumor in a 67-year-old man is reported, emphasizing the difficulty in diagnosing such rare tumors.

## Contribution

This paper adds to the limited literature on rare bladder neuroendocrine tumors through a detailed case report.

## Key findings

- A WD-NET was found incidentally in a patient without typical symptoms or risk factors.
- The case highlights the diagnostic challenges of rare bladder neuroendocrine tumors.
- Two transurethral resections were performed for tumor management.

## Abstract

Well-differentiated neuroendocrine tumors (WD-NETs) of the bladder are notably rare, representing only a small subset of neuroendocrine malignancies in this organ. We present a case of an asymptomatic 67-year-old Hispanic male in whom a WD-NET was incidentally identified during routine surveillance cystoscopy, six months following anterior urethroplasty with a buccal mucosal graft. The patient underwent two transurethral resections of the bladder tumor (TURBT). This case highlights the diagnostic challenges associated with WD-NETs given their rarity and reinforces the need for clinical awareness, even in patients without typical risk factors or symptoms.
