Kaposi's sarcoma
Kaposi's sarcoma is a malignant tumor caused by human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV) infection. It often presents as multiple macules, plaques, or nodular skin lesions, and can also affect mucous membranes, lymph nodes, and internal organs. The incidence of Kaposi's sarcoma is higher among people with AIDS. This disease has a regional distribution in Africa, and classic Kaposi's sarcoma is also prevalent in the Xinjiang region of China, mainly seen in local ethnic minorities. According to the different clinical manifestations of Kaposi's sarcoma in different high-risk populations, it can be divided into four subtypes: classic type, African type, iatrogenic immunosuppression type, and AIDS-related type.
