Breast cancer occurs in men, and its rate of incidence has increased recently. The main particularity of men's breast cancer is that its prognosis is usually worse than that of women, because it is diagnosed late and hence at advanced stage. Bilateral involvement has been reported only in rare cases. We report a case of a bilateral breast cancer, in a 47 year old patient , with no family history of breast cancer , who presented with a bilateral breast mass. Histopathological biopsy showed a bilateral invasive carcinoma, Luminal B, HER 2 negative . The extension PET scan showed no distant metastases. Bilateral mastectomy and bilateral sentinel lymph node were performed. The final histopathological exam confirmed the previous biopsy diagnostic, the tumors were mutually classified T2N0M0 of the TNM breast cancer classification. The surgical treatment was followed by tamoxifen hormonotherapy and an oncological semestriel follow-up. No recurrences or relapses were reported. The aim of our current work is to draw attention to this pathology in men, in order to contribute to its early diagnosis and therefore to improve its prognosis.
