[Multicentric Castleman disease not associated with HHV-8 and HIV viruses].

Castleman's disease (CD) is a polyclonal lymphoproliferative disorder also known as giant nodular hyperplasia or angiofollicular lymph node hyperplasia. It is a rare disease often associated to human immunodeficiency virus (HIV) and human herpes virus 8 (HHV-8). Histopathological findings in Castleman's disease suggest an exaggerated response to antigenic stimuli seen in other diseases associated with immune activation, such as rheumatoid arthritis.
