Human Herpes Virus (HHV) 8 is the likely etiological agent of Kaposi’s sarcoma (KS), and is present in all cases. HHV 8 encodes a latent nuclear antigen (LANA) that is the product of the viral gene of 73. HHV8 has also been identified in multicentric Castleman disease (MCD), and primary effusion lymphoma (PEL).
