title: HIV-associated primary body-cavity-based lymphoma: clinico-biologic features in three patients diagnosed at the same institution.
abstract: Primary effusion lymphoma (PEL) is a recently individualized form of non-Hodgkin lymphoma (WHO classification) that mainly develops in HIV infected males, more frequently in homosexuals and advanced stages of the disease (total CD4+ lymphocyte count below 100-200/mL). Occasionally, it appears in others immunodepressive states (such as solid organs postransplant period) and even, although very rarelly, in immunocompetents patients. From a pathogenetic point of view, PEL has been related to Kaposi's sarcoma-associated herpes virus (also named human herpesvirus 8) and to the clinical antecedent of Kaposís sarcoma. Relative unfrequency of this disease, the absence of wide casuistics allowing a better characterization, and its unfavorable outcome, support the need of a deeper knowledge. We present here the clinical-biological findings of three patients that were diagnosed of pleural PEL in our institution in the last two years.
