Pustular psoriasis (PP) consists of a group of severe inflammatory skin disorders with repeated eruptions of macroscopically visible, painful pustules. PP manifests as different clinical phenotypes: most commonly generalized pustular psoriasis (GPP) and palmoplantar pustulosis (PPP). The aim is to characterize epidemiology, clinical characteristics, healthcare resource utilization and costs of GPP and PPP in Finland based on data retrospectively collected from the Finnish national registers.
