Urticaria and angioedema
Urticaria is a vascular reaction of the skin characterized by the appearance of wheals, which are firm, elevated swellings of the skin. Angioedema, which can occur alone or with
urticaria, is characterized by a well-defined, edematous swelling that involves subcutaneous tissues, abdominal organs, or upper airway. Acquired C1 esterase inhibitor deficiency
