RESUMEN
INTRODUCTION: Breast cancer in males is a very rare entity, and survival is mainly influenced by the stage at diagnosis. The lack of early detection tools in men results in a diagnostic delay of about 5-10 years and a higher percentage of metastatic disease at diagnosis. However, the characteristics of head metastases are not well defined. CASE REPORTS: We present 2 cases of male breast cancer with metastases affecting cranial nervous structures and we provide imaging and histologic data. Both were middle-aged patients with ductal-type, HER-2- negative, and androgen receptor-positive primary tumors. CONCLUSION: Although central nervous system involvement is uncommon, this entity should be considered in middle-aged males with focal neurologic symptoms. More cases would be necessary to better understand the biology of this condition in order to establish an adequate diagnosis and treatment.
