Abstract

Pityriasis rubra pilaris (PRP) is a chronic dermatosis characterized by scaling of the scalp, erythema and scaling of the face and neck, hyperkeratosis of the palms and soles, and keratotic follicular plugs of the extremities and trunk. An 11½-year-old girl is presented with the clinical and histological features of PRP.

An analysis of 173 case reports of PRP from the English language literature revealed onset of this condition at any age from birth to 70 years with no significant age or sex predilection. The most frequently affected areas at onset are the face and neck, and the palms. No laboratory test other than the skin biopsy has any diagnostic value. Many regimens have been used in the treatment of PRP but their exact value is uncertain.
