Key Message:
The literature regarding the characteristics and underlining mechanisms of chronic spontaneous urticaria in children is limited.
This retrospective cohort study included 250 children with chronic spontaneous urticaria. Chronic spontaneous urticaria in children is a self-limited disease. Urticaria lasted up to 2 years in most of the children. One third had at least one atopic disease. Atopic dermatitis and allergic rhinitis were the most prevalent, and significantly more common than in the general pediatric population.
