Kaposi's sarcoma is a rare tumor associated with human herpes virus 8 (HHV-8)
infection. Four main clinical subtypes have been described. This study reports
on a form of KS in an HIV negative and immunocompetent middle-aged man. The only
remarkable factor is that he has sex with other men. This form of Kaposi's
sarcoma is rare. It occurs more in younger patients than in the classic form, is
limited to the skin, and is associated with a good prognosis. The means of
transmission of the virus is through saliva in oroanal or orogenital sexual
practices. Mechanisms of tumor development are still not well known. Given the
possible increased number of this variant, it would be interesting to extend
this study.
