Acute generalized exanthematous pustulosis and polyarthritis associated with a novel CARD14 mutation

Abstract

Acute generalised exanthematous pustulosis (AGEP) is a rare toxicoderma characterised by an acute onset rash, with many sterile pustules on the surface, high fever and increased acute phase reactants. We report the case of a patient who presented to the dermatology department with an AGEP and polyarthritis, in which a novel CARD14 mutation was identified. The pathophysiological mechanism of AGEP remains unclear, although mutations in the IL36RN gene have been identified in a small subset of AGEP patients. Similarly, mutations in the CARD14 gene have been linked to pustular types of psoriasis and familiar cases of pityriasis rubra pilaris; however, there are no reports associating mutations in the CARD14 gene with AGEP.
