Synchronous bilateral breast cancer in men: a case report and review of the literature.

Breast carcinoma is a rare disease in men, and bilateral cases are extremely uncommon. The rarity of male breast carcinoma and the small number of large studies on this topic have made it necessary to extrapolate treatment standards and outcomes from those established for women. Between 1997 and 2007, 75 men with breast cancer were referred to our institute, and the bilateral case we present here was the only one we have observed since 1994. The goal of our work was to contribute to the available literature with this extremely unusual presentation of the disease.
