[Physical urticaria and angioedema in children].

Urticaria and physical angioedema frequency is hard to evaluate in children. In this series, we keep 53/1000. Physical urticaria is found in 36% of the cases and concerns cholinergic urticaria, urticaria to cold, idiopathic dermographism and mastocytosis, and delayed urticaria to pressure. The authors insist on the interest of the etiologic research in these forms of infantile urticaria.
