# The Chest Wall Mass of Unknown Origin: A Rare Presentation of Esophageal Adenocarcinoma

## TL;DR

A rare case of esophageal cancer presented as a chest wall mass, leading to a delayed diagnosis and poor outcome.

## Contribution

Highlights an unusual presentation of esophageal adenocarcinoma metastasis to the chest wall.

## Key findings

- Chest wall mass was a rare presentation of esophageal adenocarcinoma.
- Delayed diagnosis resulted in advanced-stage disease and poor outcome.

## Abstract

A chest wall mass can result from a diversity of underlying disease processes ranging from benign to a site of distant metastasis. The chest wall is a rare site for esophageal adenocarcinoma (EAC) metastasis. Delayed diagnosis can occur when presenting symptoms are not typical of esophageal pathology, and advanced-stage EAC has a high morbidity and low survival rates. Our case demonstrates a rare and unusual presentation of EAC with a poor outcome due to delayed diagnosis.
