a localized edematous reaction of the deep dermis or subcutaneous or submucosal tissues appearing as giant wheals; urticaria
is the same physiologic reaction occurring in the superficial portions of the dermis.
hereditary angioedema an autosomal dominant disorder of the complement system manifested as recurrent episodes of edema of the skin, upper respiratory tract, and gastrointestinal tract. It may be mediated by such factors as minor trauma, sudden changes in environmental temperature, and sudden emotional stress. adj., adj angioede´matous.
Recurrent large circumscribed areas of subcutaneous or mucosal edema of sudden onset, usually disappearing within 24 hours; frequently, an allergic reaction to foods or drugs.
angioedema /an·gio·ede·ma/ (-ĕ-de´mah) a vascular reaction involving the deep dermis or subcutaneous or submucosal tissues, representing localized edema caused by dilatation and increased permeability of the capillaries, and characterized by the development of giant wheals.
hereditary angioedema an autosomal dominant disorder of C1 inhibitor (C1 INH), which causes uncontrolled activation of the classical complement pathway, manifested as recurrent episodes of edema of the skin and upper respiratory and gastrointestinal tracts with increased levels of several vasoactive mediators of anaphylaxis. It may be mediated by such factors as minor trauma, sudden changes in environmental temperature, and sudden emotional stress.
Rapid swelling of the subcutaneous tissues and submucosal membranes, often accompanied by urticaria.
a dermal, subcutaneous, or submucosal swelling that is acute, painless, and of short duration. It may involve the face, neck, lips, larynx, hands, feet, genitalia, or viscera. Angioedema may be hereditary or the result of a food or drug allergy, an infection, emotional stress, or a reaction to blood products. Treatment depends on the cause. Severe angioedema may require subcutaneous injections of epINEPHrine, intubation, or tracheotomy to prevent respiratory obstruction. Prevention depends on the identification and avoidance of causative factors. Also called angioneurotic edema.

angioneurotic oedema (1) Acquired angioedema, a chronic and potentially fatal condition characterised by abdominal pain and episodic localised subcutaneous, periorbital, periocular and laryngeal oedema, due to an absence of C1 esterase inhibitor.
Recurrent oedema; abdominal pain; laryngeal oedema, which may compromise breathing.
History of recurrent angioedema, abnormally low or absent C1 esterase inhibitor in blood.

Recurrent large circumscribed areas of subcutaneous or mucosal edema of sudden onset, usually disappearing within 24 hours; often due to an allergic reaction to foods or drugs.
Synonym(s): angioneurotic edema
a condition characterized by the sudden and temporary appearance of large areas of painless swelling in the subcutaneous tissue or submucosa, with or without pruritus. Caused by immunological reactions, usually immediate type hypersensitivities. Sometimes referred to as angioneurotic edema.
in humans, the periodic occurrence of angioedema caused by a deficiency of the complement regulatory protein.
Patient discussion about angioedema
Q. Is severe diarrhea sign of angioedema? I have sudden onset of painful diarrhea with stomach pain.
A. Severe diarrhea can be a sign of angioedema but it is a very unlikely way of angioedema to show, especially if that is the only symptoms and there is no obvious seen swelling of skin or shortness of breath. Stomach ache with diarrhea is usually caused by an infection, most likely a viral infection, and should pass within a few days. If symptoms are unbarable or continue, you should see your doctor.
Q. What can cause an angioedema on 15 year old girl? I’ve been getting angioedema signs on my left arm for the past few weeks, not severe but it itches and sure don’t help my low-as-it-is self esteem…
