Abstract: The purpose of this research is study the clinical manifestation and classification of Kaposi sarcoma in Africa children, and to analyze the incidence of Kaposi sarcoma associated with HIV infection in pediatric patients. Clinical data of 14 cases were collected. All cases received histopathologic examination, and 14 cases accepted HIV antibody test. Histopathologic examination to 14 cases conformed to the diagnosis of KS and 12 out of 14 tested cases were HIV positive. Among 12 HIV positive cases, the 6-months-to-3-years group accounted for 41.7%. Other three groups accounted for 8.3 %, 25.0%, 25.0% respectively. For the 12 HIV positive cases, lymphatic KS was the main clinical type and occupied 75%. The incidence of pediatric KS associated with HIV infection was not uncommon. Among 12 HIV positive cases, the incidence of the 6-months-to-3-years group was much higher than the other three groups; lymphatic KS was the main clinical type. The result also suggests the possibility of canceration of HIV lymphadenopathy. The delayed diagnosis for most cases requests more attention to this particular problem.
