摘要
Recently, a novel γ-2 herpes virus HHV-8 or KSHV has been associated with various forms of Kaposi's sarcoma (KS). Subsequently it was also found in so called body cavity based lymphomas (BCBL) or primary effusion lymphomas (PEL) of AIDS patients and some cell lines derived from such lymphomas. Most PEL cases have been found in AIDS cases, but a few also in HIV negative patients.
