Male breast cancer is an infrequent disease representing only about 1% of all breast cancers responsible for 0.1 % cancer deaths in men. The incidence has increased over the past 25 years. Genetic, hormonal, and environmental risk factors have been implicated in its pathogenesis. Clinical presentation is a painless retroareolar lump, or nipple inversion with more than 40% of individuals having stage III or IV disease. In most cases diagnosis is established by clinical assessment, mammography, ultrasonography and core biopsy. About 90% of all tumors are invasive ductal carcinomas, expressing high levels of hormone receptors. Locoregional treatment includes surgery and radiotherapy, according to the clinical presentation, and systemic treatment (hormonal and/or chemotherapy) according to clinical and biological features. In this article we present the case of a patient with the disease and review the latest information on this subject.
