Acquired immunodeficiency syndrome-associated non-Hodgkin's lymphoma.

The clinical picture is of aggressive high and intermediate grade lymphoma with extranodal presentation either as the first manifestation or during the course of HIV infection. The dramatic growth of tumors, leukopenia, opportunistic infections, and pre-existing AIDS-related problems of KS and chronic infections have made treatment extremely difficult. New regimens using short courses of chemotherapy, GM-CSF, and antiviral therapy have raised hopes that these measures will lead to improved survival.
