# A Case of Metastatic Urothelial Carcinoma-Associated Acute Esophageal Necrosis

## TL;DR

## Contribution

This case report highlights a rare association between metastatic urothelial carcinoma and acute esophageal necrosis.

## Key findings

- The patient had a history of metastatic urothelial carcinoma.
- The patient was diagnosed with acute esophageal necrosis characterized by black mucosa.

## Abstract

Acute esophageal necrosis is a rare syndrome with endoscopic findings of a diffuse circumferential pattern of black mucosa. Although underlying pathogenesis is unclear, it is known to have associations with malignancy. We present a rare case of a patient with a history of metastatic urothelial carcinoma who was found to have acute esophageal necrosis.
