A Prostate Carcinoma Metastasized to Bilateral Breasts / 대한비뇨기과학회지

ABSTRACT

Antiandrogens are generally used for the treatment of prostate cancer, with gynecomastia the most common adverse event seen during therapy. However, a breast mass in a man with a carcinoma of the prostate may represent a metastatic disease or, less often, a primary carcinoma of the breast. Clinically diagnosed metastatic prostate cancer to the breast is a rare event. Breast metastasis represents an end-stage manifestation of the cancer, with an extremely poor prognosis. Herein, the case of a 62-year-old man, who presented with bilateral breast masses 7 months after antiandrogen therapy for the treatment of prostate cancer, is reported. An excisional biopsy of the breast mass revealed a metastatic prostatic adenocarcinoma.
