Pityriasis rubra pilaris in black South Africans.

Eighteen black South African patients with pityriasis rubra pilaris were prospectively studied, nine adults and nine children; patients with the classical types (namely I and III) constituted 75% of the group. Follicular involvement was very prominent, especially in the children with type III, but otherwise the clinical and histological findings did not differ from those reported in white patients. This is the first series of black African patients with this condition to be reported.
