Abstract

Pityriasis rubra pilaris (PRP) is a rare group of hyperkeratotic, papulosquamous disease that can be acquired or inherited. There have been reported cases of rheumatologic associations, mainly arthritis and dermatomyositis. In this review article, we will explore the clinical presentation and classification, rheumatologic associations and treatment modalities of PRP. In addition, we will also report a case of PRP with seronegative arthritis.
