# A Case of Esophageal Adenocarcinoma Metastatic to the Breast

## TL;DR

This paper reports a rare case of esophageal cancer spreading to the breast, highlighting the challenges in diagnosing such metastases.

## Contribution

The paper presents a unique case of esophageal adenocarcinoma metastasizing to the breast, which is exceptionally rare.

## Key findings

- Esophageal adenocarcinoma can metastasize to the breast, though it is an uncommon occurrence.
- Metastatic breast lesions from esophageal cancer can mimic primary breast cancer in clinical and radiographic features.
- This case emphasizes the need for increased diagnostic awareness of such rare metastatic patterns.

## Abstract

Metastatic carcinoma infiltrating the breast from extramammary malignancies is an infrequent occurrence. Extramammary carcinomas that may be metastatic to the breast include gastrointestinal cancers, ovarian cancer, and lung cancer, among others. These metastatic lesions often pose a diagnostic challenge, resembling primary breast cancer in both clinical and radiographic presentations. The incidence of esophageal cancer metastasizing to the breast is low. Esophageal cancer more commonly spreads to locoregional lymph nodes, lungs, liver, and bone. We present a unique case where primary esophageal adenocarcinoma metastasized to the breast. Our aim is to raise diagnostic awareness by delineating the clinical and pathological findings of this exceptionally infrequent disease.
