Kaposi's sarcoma (KS) is a tumor caused by Kaposi's sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus 8 (HHV8). Despite its name, it is generally not considered a true sarcoma, which is a tumor arising from connective tissue. KS actually arises as a cancer of lymphatic endothelium and forms vascular channels that fill with blood cells, giving the tumor its characteristic bruise-like appearance. KS was historically very rare and found mainly in older men of Mediterranean, Jewish or African origin (classic KS), or patients with severely weakened immune systems, such as after an organ transplant (immunosuppressive treatment related KS). In the early 1980s KS began to be seen in AIDS patients. This led to the belief that AIDS weakened the immune system. Kaposi's sarcoma-associated herpesvirus is responsible for all forms of KS. less
