[Kaposi's sarcoma associated with acquired immunodeficiency syndrome]

AIDS-related Kaposi's sarcoma (KS) accounts for 15-20% of cases of AIDS. Clinical presentation is similar to that of classical KS but with an overall more aggressive evolution and cutaneous dissimilation. There is no particular predilection for the lower limbs and frequent lesions are located on the face. Most of the cases have occurred in homosexual males with a moderate immune deficiency (mean CD.4 = 300/mm3). This predilection for gay people has not yet received explanation and the physiopathology of KS is unclear. Treatment of KS with interferon or chemotherapy (Bleomycin) is effective in 30-50% of cases.
