Hereditary angioedema is a rare disease with autosomal dominant inheritance that is characterized by edema in skin and mucosa of various organs, mainly gastrointestinal tract and the respiratory system. Clinical manifestations may be mild or severe, depending on their location and intensity. The most severe forms are edema of the glottis, and the edema of gastrointestinal tract which can cause severe dehydration and abdominal pain that can be confused with an acute abdomen and unnecessary surgery. The edema is characterized by not being itchy, no temperature rise, non-marking when pressed and usually have a family history. No predilection for sex, or skin color. Its diagnosis is necessary to make a thorough examination and additional tests of the complement system. They described two classic forms called HAE type I and type II, type I is the most common. Recently it described the type III that occurs only in females, without quantitative or qualitative alteration of C1 inhibitor and is associated with the consumption of drugs or oral contraceptives containing estrogen. The treatment is based primarily on the use of attenuated androgens or antifibrinolytic and avoiding risk factors if they are known. In cases of acute conditions present you can use fresh frozen plasma and purified C1 inhibitor concentrate (Berinert-500) for intravenous use and rapid response; but the use of subcutaneous epinephrine may not be very effective. Steroids and antihistamines have no effectiveness when used in these patients.
