Among 1,230 new patients with skin disease belonging to different tribes in Kenya, 32 instances (2.6%) of psoriasis were diagnosed. In most of the patients, the clinical diagnosis was supported by histopathological investigations. The occurrence of psoriasis appears to be far higher than is usually accepted for nonwhite races. Our findings are compared with those of other areas in Africa and with the Negro population in the United States.
