[AIDS and its association with human tumors and viruses. A viral and/or immunogenetic cause?]

This paper is an editorial review of the relationship between the AIDS, Kaposi sarcoma, adult-T-lymphoma, other neoplasias, HTLV, ATLV and other viruses, amyl-nitrite and immunosuppressive drugs and the possible immunogenetic mechanism related to the immunity suppressor branch due to Ia antigen allogenic reaction similar to that of graft versus host reaction which may also induce angiosarcomas.
