Actinic prurigo: A retrospective analysis of 21 cases referred to an Australian photobiology clinic

Abstract

Actinic prurigo (AP) is a rare acquired idiopathic photodermatosis, reported most often in American Indians, but also in Caucasian and Asian populations. The skin lesions in AP predominantly affect exposed sites but may involve covered areas, and often result in postinflammatory scarring. The diagnosis of AP can be difficult and relies on a combination of history, clinical experience and investigations including phototesting and human leucocyte antigen typing.

The mean age of patients at presentation to the clinic was 25 years, wi..
