Clinical features and outcome of primary effusion lymphoma in HIV-infected patients: a single-institution study.

Purpose: To describe the clinical features and outcome of HIV-associated primary effusion lymphoma (PEL) and to compare them with those of the other HIV-associated non-Hodgkin's lymphomas (NHLs).

Patients And Methods: From April 1987 to June 2002, 277 patients with HIV infection and systemic NHL were diagnosed and treated in our institution. Clinical features and outcome of PEL patients were compared with the features and outcomes of 162 patients belonging to the following histologic subtypes: plasmoblastic lymphoma of oral cavity (PBLOC, n = 11), immunoblastic lymphoma (IBL, n = 76), and centroblastic B-cell lymphoma (CBCL, n = 75).
