Psoriasis is a chronic inflammatory dermatosis that very rarely involves the oral mucosa. There is no consistent pattern of clinical presentation in the oral cavity. Furthermore, manifestations of intraoral psoriasis in paediatric patients are extremely rare and only one case appeared to have been reported in the literature to date. In this paper we report a case of intraoral psoriasis in an 11-year-old child who had been previously diagnosed as having dermal psoriasis.
