Breast J. 2020 Mar;26(3):517-519. doi: 10.1111/tbj.13580. Epub 2019 Sep 20.


A 47-year-old male presented to our clinic with complaints of mass in both breasts. In the patient's history, he had undergone low anterior resection for rectum mucinous adenocarcinoma 2 years ago. The masses in both breasts of the patient were excised. Mucinous adenocarcinoma metastases were reported in the pathologic evaluation of the masses. Metastasis should be considered in patients with bilateral breast mass and previously diagnosed cancer even if the patient is male.

Keywords: adenocarcinoma; bilateral metastasis; breast cancer; rectal cancer.
