    Abstract:
    In order to evaluate a possible role of viral infections in the pathogenesis of AIDS-associated Kaposi's sarcoma (KS), we investigated 26 cutaneous AIDS-associated KS by polymerase chain reaction (PCR), in situ hybridization, and immunohistochemistry. By PCR we detected human papilloma viruses (HPV), cytomegalovirus (CMV), human herpesvirus 6 (HHV-6), and for the first time human herpesvirus 7 (HHV-7) in the KS. The prevalence of HPV, HHV-6, and HHV-7 was similar to or lower in KS than in normal skin tissues of AIDS patients without KS, but higher than in normal skin of HIV-seronegative patients. All HHV-6 found in KS were identified as HHV-6 variant B. In addition to the known HPV types 16 and 18 described in KS, we also found HPV types 6 and 33 in KS specimen. By immunohistochemistry HHV-6 could be localized in macrophages in KS, in the adjacent stroma as well as in normal skin of control cases. In situ hybridization for CMV and HPV gave negative results in KS and controls.
