A lymphoma is a type of cancer arising from lymphoid cells. In AIDS, the incidences of non-Hodgkin's lymphoma, primary cerebral lymphoma and Hodgkin's disease are all increased. There are three different varieties of AIDS-related lymphoma: Diffuse large B-cell lymphoma, B-cell immunoblastic lymphoma, and Burkitt's lymphoma (small non-cleaved cell lymphoma).
The symptoms of AIDS-related lymphoma can include: weight loss, fever, and night sweats.
Non-Hodgkin's lymphoma (NHL) is present in about 1-3% of HIV seropositive people at the time of the initial diagnosis of HIV. However, it is believed that such patients have been seropositive for a prolonged period, but have simply not had their infections recognized previously. This is so because immunodysregulation must exist for an extended interval of time, in order for a lymphoproliferative process to evolve in that context.
Primary cerebral lymphoma
Primary cerebral lymphoma (or primary central nervous system lymphoma) is a form of NHL. It is very rare in immunocompetent people, with an incidence of 5–30 cases per million person-years. However the incidence in immunocompromised individuals is greatly increased, up to 100 per million person-years.
Treatment of AIDS patients with antiretroviral drugs reduces the incidence of primary cerebral lymphoma.
The incidence of Hodgkin's disease in the general population is about 10–30 per million person-years. This increases to 170 per million person-years in HIV positive patients.
