Abstract and Introduction

Pityriasis rubra pilaris is a skin condition with many different clinical presentations. History, histology, clinical presentation, its different classified forms, treatments, and differential diagnoses are reviewed.

Pityriasis rubra pilaris (PRP) is a red scaly eruption characterized by the association of palmoplantar keratoderma, follicular plugging, and erythematous perifollicular papules which may progress to plaques or erythroderma (White, 2003). Most cases are sporadic and acquired but a familial form may exist which is transmitted by an autosomal dominant or autosomal recessive mechanism.

This disease was first described by Devergie in 1856 who characterized PRP as a follicular eruption and noted its association with three other cutaneous disorders: psoriasis palmaris, pityriasis capitis, and pityriasis rubra. In 1877, Richaud recognized that all of the manifestations were of the same disorder. In 1889, Besner added the epithet rubra (White, 2003).
