introduction: primary lymphoma of the central nervous system (pcnsl) is a major cause of mortality in primary tumors of the central nervous system, plus there are only a few epidemiological data today, these are the reasons why it was decided to make a report of cases in the group of neuropathology at the university of antioquia. objetives: to describe the behavior of this disease in group of patients. materials and methods: we reviewed the pathological studies and clinical records of 12 patients diagnosed with pcnsl in the service of neuropathology at the university of antioquia from the years of 2004 to 2011. results: there were 12 patients who met the inclusion criteria. of these patients, 61.5% were male and 38.5% women. the average age at diagnosis was 42.6 years (1 - 77 years). the giant cell, diffuse pattern b non-hodgkin lymphoma was the most frequent tumor with 83.3%,t- cell lymphoma with 8.35%, burkitt lymphoma 8.35%; 33.3% of the patients were immunodeficient. conclusion: in this series of patients with central nervous system lymphoma similar clinical characteristics were found to those in the medical literature, perhaps the only different finding was a higher rate of patients without an apparent alteration in the immune system.
