Metastasis to the breast from extramammary malignancies is rare. This is the third case report of metastatic breast cancer from esophageal cancer. We report the clinical, radiographic, and pathologic findings of a 57-year-old woman who underwent esophagectomy for esophageal cancer and developed metastatic cancer 2 years later. Pathologic examination of a resected specimen of the breast revealed squamous cell carcinoma invading the mammary glands. Estrogen receptor and axillary lymph node metastasis were negative with immunostaining. She is alive 6 months after the modified radical mastectomy.
