Breast Metastasis from Esophagogastric Junction Cancer : A Case Report

Abstract EN

Metastasis to breast from nonmammary malignancy is only about 1.3–2.7%.

A few cases of squamous cell carcinoma of esophagus and adenocarcinoma of stomach metastasizing to breast have been reported, but this is probably the first report of breast metastasis from esophagogastric junction (EGJ) cancer in the English literature.

Herein we report a case of a 32-year-old patient diagnosed as adenocarcinoma of gastroesophageal junction, presenting with left breast metastasis two years after treatment.

Given unusual site of metastasis in a follow-up case of EGJ cancer, not only it is challenging to differentiate it from primary carcinoma of breast but also it is important from treatment point of view.

In our case, clinical data, radiology, histopathology, and immunohistochemistry (IHC) led us to reach the diagnosis.
