Kaposi's sarcoma

Kaposi's sarcoma is a type of cancer that forms purple or brown patches, nodules, or tumors on the skin and other organs. It develops from the cells that line blood vessels or lymph vessels. Often associated with weakened immune systems, especially in individuals with HIV/AIDS or those on immunosuppressive therapy, it can also affect internal organs like the lungs or digestive system. While it appears as skin lesions initially, it can sometimes spread internally. Treatment varies depending on the extent but may include antiretroviral therapy or chemotherapy to control growth and improve symptoms.
