AIDS-associated malignant lymphoma.

Lymphoma has been well described in various states of congenital, acquired, and iatrogenic immune dysfunction, and the clinical and pathologic characteristics in these settings are similar to those seen in patients with HIV-induced immunodeficiency. High grade B cell lymphomas are expected, with widespread extranodal disease at the time of initial presentation. Unusual sites of disease may be seen, such as the CNS. Factors predictive of short survival include low performance status, history of AIDS prior to the diagnosis of lymphoma, stage IV or bone marrow involvement, and low CD4 cells. Use of intensive multiagent chemotherapy may be associated with demise from opportunistic infections. Less intensive regimens may be indicated in patients with poor prognostic indicators, whereas patients lacking these factors may be able to tolerate greater dose intensity.
