Epidemic Kaposi sarcoma is a type of cancer that primarily affects individuals with HIV/AIDS. It is characterized by the growth of tumors in the skin, lymph nodes, and other organs. This form of Kaposi sarcoma is linked to the human herpesvirus 8 (HHV-8), which is more prevalent in people with weakened immune systems. The disease often presents as purple or brown lesions on the skin and can also cause swelling and discomfort. Early diagnosis and treatment are crucial, as epidemic Kaposi sarcoma can progress rapidly if left untreated. Treatment options may include antiretroviral therapy, chemotherapy, and radiation.
