Studysummary This study suggests that using the International Psoriasis Council's classification, which includes body surface area, special areas, and treatment history, may identify more candidates for systemic therapy than by body surface area alone.

The study analyzed psoriasis severity in a real-world population using data from 5,120 patients, considering body surface area (BSA), special area involvement, and treatment history. Results showed that 34.6% of patients had a BSA > 10%, and 45.5% had involvement in 2 or more special areas (face, scalp, palms/soles, nails, genitalia). Notably, the proportion of patients with 2+ special areas was consistent at around 45% across all BSA categories. These findings indicate that the International Psoriasis Council's classification, which includes special area involvement, could identify more patients who might benefit from systemic treatment compared to using BSA alone.
