Lymphomas associated with human immunodeficiency virus (HIV) will prob
ably become an increasing problem with improved survivals of infected
individuals in an immunosuppressed state because of the advances in an
tiretroviral treatment and the therapy of opportunistic infections. In
an attempt to aid the understanding of the many aspects of the this g
rowing problem, the current thinking about the epidemiology, pathology
, biological and clinical features, and treatment of the systemic HIV-
associated non-Hodgkin lymphomas is reviewed. The important features o
f the HIV-associated central nervous system lymphomas are also describ
ed. Finally, there is a discussion of Hodgkin's disease in HIV-infecte
d individuals.
