Depending on the nature of the occurrence,two types of Quincke edema: allergic and pseudoallergic (hereditary angioedema). Quincke's allergic edema, like other allergic diseases, develops as a result of the body's response to the penetration of a specific allergen; the disease is often combined with bronchial asthma, food allergy, and pollinosis. Hereditary angioedema is a rare genetic disease associated with the deficiency of the C1 inhibitor of the complement system.
