Pityriasis Rubra Pilaris: An Uncommon Presentation

Abstract

Human immunodeficiency virus (HIV) associated pityriasis rubra pilaris (PRP) or PRP Type VI is a distinctive entity reported in HIV patients. We report a patient with skin Type V (based on the Fitzpatrick scale), and HIV infection, presenting with an atypical clinical manifestation (non-acneiform), and with an uncommon distribution of this entity but characteristic histological findings of Type VI PRP. We review the clinical features, pathology and possible aetiology of this entity.
