Abstract:
Pityriasis rubra pilaris (PRP) is a rare papulosquamous disease of unknown aetiology, with an estimated prevalence of 2.5 per million.1 It is clinically characterised by the presence of follicular hyperkeratotic papules, but the histopathology is usually non-specific. An interesting case of asymmetric, inflammatory arthritis of the hand in a patient who also presented with PRP is presented, along with a review of the few previously reported cases the literature.
