Kaposi sarcoma is a rare form of cancer that may cause lesions to develop on the skin and in the lining of the mouth, or tumors in different organs and systems of the body—such as the respiratory system and the gastrointestinal tract. Our doctors were among the first to recognize the condition in people with HIV or AIDS in the 1980s, and have extensive experience in diagnosing and managing several types of Kaposi sarcoma. Our imaging specialists, infectious disease specialists, dermatologists, and oncologists work together to create a personalized treatment plan for you.
