title: Human herpes virus-8 associated with two cases of primary-effusion lymphoma.
abstract: Primary-effusion lymphoma (PEL) is a rare form of non-Hodgkin's lymphoma which predominantly occurs in patients with acquired immunodeficiency syndrome and is characterized by the presence of a malignant effusion in one or more of the body cavities, generally in the absence of a primary tumor mass. Recently, we encountered two cases of PEL presenting as cardiac tamponade. In both cases, a diagnosis of diffuse large B-cell lymphoma was made by examination of the pericardial fluid. Because human herpes virus-8 (HHV-8) antibodies were positive and human immunodeficiency virus antibodies were negative, HHV-8 seemed likely to be an etiologic agent for the PEL. One of the two patients (case 1) was not treated for religion reasons and died. The other (case 2) achieved complete remission after treatment using the CHOP regimen and is alive at present. The prognosis of this disease is believed to be poor, therefore more cases should be collected to establish reliable therapy for PEL.
