title: Cerebral Metastasis from Breast Cancer in a Male Patient with HIV.
abstract: Context. Breast cancer (BC) in men is a rare condition, corresponding to 1% of all neoplasms in this gender. Some studies show that up to 93% of BC cases in men are advanced disease. If its occurrence constitutes an uncommon fact, the appearance of a metastasis to the central nervous system (CNS) is extremely rare. The objective of the present study is to present the case of a male patient, bearer of HIV infection, who presented with BC and later metastasis to the CNS. We also include a brief review of the literature. Case Report. We describe a case of a male patient, 59 years old, with HIV infection and a history of BC treated 4 years earlier, which progressed into headache and vertigo. Neuroimaging exams showed lesions suggestive of cerebral metastasis and a stereotaxic biopsy confirmed BC metastasis. Conclusion. Breast cancer in men with metastasis to the CNS is a rare condition and similar reports were not found in the available databases. It should be pointed out that even though rare, it should be considered among the differential diagnoses for SNC metastases in men, although HIV infection favors the appearance of some types of cancer.
