Kaposis sarcoma (KS) in equatorial Africa, mainly in Kenya, and of AIDS were studied geopathologically and histopathologically. The results obtained in western Kenya during the period 1979-1983 were as follows: 1) KS accounts for 73 cases (2.80%) out of the total of 2, 607 maligant tumors of surgical specimens. 2) The high incidence of KS is found between the age of 50 to 59. 3) Male to female ratio is 7.5:1.0. 4) In adults, the most common site of the body of primary lesion is the foot, followed by the leg, the hand and the forearm. 5) In children, KS is predominantly primarily of lymphatic origin. 6) The high tribal incidence is found among the Luhya and the Luo who are living in Western and Nyanza provinces respectively. KS is classified epidemiologically and clinically into several categories: a) Endemic type in Africa, classical type in Europe and US, and epidemic type of AIDS, b) Cutaneous type, lymphatic type and visceral type, c) Acute or aggressive type and chronic or slightly benign type, d) Adult type and infantile type. KS was divided histologically into three types; hemangiomatous, fibrosarcomaoous and anaplastic types. KS of African endemic and US classic types were fibrosarcomaotus pattern predominant, while some of KS in AIDS were hemangiomatous.
