Key clinical point: In pediatric patients, psoriasis vs psoriatic arthritis (PsA) was associated with greater body surface area (BSA) involvement particularly in the extremities, scalp, trunk, genitals, face, skin folds, and nails.
Major finding: The median BSA affected by psoriasis was higher in patients with psoriasis vs PsA (19.7% vs 6.1%; P = .029), with significantly greater disease distribution observed in extremities (75% vs 24%), scalp (61% vs 28%), trunk (58% vs 10%), and genitals (38% vs 10%; P < .05 for all).
Study details: Findings are from a retrospective case-control study that included pediatric patients (age < 18 years) with psoriasis (n = 64) or PsA (n = 29) who were matched by age and sex.
Disclosures: This study did not receive any external funding. The authors declared no conflicts of interest.
