The goal of this observational registry study is to characterize the clinical, epidemiological, and therapeutic features of patients with generalized pustular psoriasis (GPP) in Costa Rica through a standardized national registry. The main question it aims to answer is: What are the clinical, epidemiological, and therapeutic characteristics of patients with generalized pustular psoriasis registered in the country, and how do these relate to disease severity and evolution? Patients with GPP receiving routine dermatologic care in participating centers will have their demographic, clinical, severity, comorbidity, and treatment data recorded using a standardized case report form. Clinical assessments (e.g., GPPASI, PASI/BSA, DLQI), laboratory results, triggers, complications, and therapies will be documented and updated during periodic follow-up visits as part of usual care.
