title: Keratosis circumscripta. A distinct dermatological entity or a variant of psoriasis?
abstract: 45 cases of a dermatosis believed to be the same as those originally described by Schrank in 1963 among Nigerian children of Yoruba ethnic origin and named keratosis circumscripta by him are reviewed. All evidences point towards the fact that the dermatosis observed by us as well as those originally described by Schrank are a variant of psoriasis possibly modified by environmental factors. It has therefore been suggested that this dermatosis should not be regarded as a new dermatological entity, and that the original names should be modified. To reflect the original work done by Schrank as as well as the true clinical picture of this dermatosis, the nomenclature psoriasis circumscripta with palmo plantar keratosis is suggested.
