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.
