KAPOSI'S SARCOMA (KS)

an abnormal or cancerous proliferation of cells and blood and/or lymph vessels causing tumors on the skin, mucous membranes and/or internal organs. KS typically appears as pink or purple flat or raised lesions. Types include classic KS, African KS, and AIDS-related or transplant-related KS. KS is associated with a herpesvirus (KSHV, or HHV-8). It occurs more commonly among HIV positive gay and bisexual men than among others with HIV disease, indicating that it may be sexually transmitted.
