AIDS-Related Primary Central Nervous System Lymphoma
Primary central nervous system lymphoma (PCNSL) is a rare extra-nodal B-cell non-Hodgkin lymphoma, which arises in the brain, spinal cord, meninges, or eyes. In individuals infected with HIV, PCNSL occurs with advanced immunosuppression and low CD4 T-cell count. It is considered an AIDS-defining malignancy. Unlike PCNSL in immune-competent hosts, AIDS-related PCNSL (AR-PCNSL) is almost exclusively caused by a cancer-causing herpesvirus, Epstein Barr Virus (EBV, also known as human herpesvirus-4). While PCNSL in immune-competent patients and AR-PCNSL have pathological and clinical overlap, AR-PCNSL is distinguished by its strong association with immunosuppression and viral etiology.
Primary central nervous system lymphoma (PCNSL) is a rare extra-nodal non-Hodgkin lymphoma, which accounts for approximately 3–5 % of primary brain tumors. Prior to effective therapy for HIV, a large proportion of cases of PCNSL, especially in younger individuals, occurred in severely...
