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.
Allergies (e.g., foods, pollen, insect bites); drugs (e.g., ACE inhibitors, salicylates); stress; exposure to cold, water, sunlight or heat.
Epinephrine, antihistamines, corticosteroids (androgens).

1. A general term for a vascular reaction of the deep dermis, subcutaneous or submucosal tissues, which corresponds to localized edema 2º to vasodilation and ↑ capillary permeability.
1. Recurrent large circumscribed areas of subcutaneous edema of sudden onset, usually disappearing within 24 hours; seen mainly in young women, frequently as an allergic reaction to foods or drugs.
An allergic skin disease characterized by patches of confined swelling involving the skin the layers beneath the skin, the mucous membranes, and sometimes the viscera—called also angioneurotic edema, giant urticaria, Quincke's disease, or Quincke's edema.

angioedema recurrent, sudden-onset, non-inflammatory swelling of skin and mucous membranes, viscera and brain; characteristic of anaphylaxis
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
angioedema (angioneurotic edema, Quincke's disease) (an´jēōədē´mə),
the spontaneous swelling of the lips, cheeks, eyelids, tongue, soft palate, pharynx, and glottis, frequently associated with allergy to food or drugs and lasting from several hours to several days. Involvement of the glottis results in obstruction of the airway.
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…
A. The following may cause angioedema - More discussions about angioedema
Certain medications (drug allergy)
Exposure to water, sunlight, cold or heat
Foods (such as berries, shellfish, nuts, eggs, milk, other)
Hives or angioedema may also occur after an illness or infection.
