[Multicenter Castleman disease in AIDS. Its relationship with HHV-8 or herpes virus associated to Kaposi's sarcoma. Study of two cases].

Castleman disease is considered a reactive lymphadenopathic picture with two clinical forms: one localized, frequent in immunocompetent patients and another multicenter one that is more characteristic in immunodepressed patients. Two cases of Castleman disease multicenter in HIV positive patients with Kaposi's sarcoma are presented. Both patients have multiple adenopathies, hepatomegaly and symptoms B on diagnosis. One of them had a favorable response to chemotherapy treatment and another died. A review of the concept of multicenter Castleman disease and its pathogenic relationship to human herpes virus 8 (HHV-8) is done.
