Pictures of Angioedema (Angioneurotic Edema)
This page was last updated: September 17, 2014

Angioedema is characterized by painless, nonpruritic, nonpitting, and well-circumscribed areas of edema due to increased vascular permeability. Angioedema is most apparent in the head and neck, including the face, lips, floor of the mouth, tongue, and larynx, but edema may involve any portion of the body. In advanced cases, angioedema progresses to complete airway obstruction and death caused by laryngeal edema. Angioedema may involve the gastrointestinal tract, leading to intestinal wall edema, which results in symptoms such as colicky abdominal pain, nausea, vomiting, and diarrhea.

What is Hereditary Angioedema?

Hereditary Angioedema (HAE) is a rare and serious genetic condition occurring in about 1/10,000 to 1/50,000 individuals. The disease is characterized by episodes of edema (swelling) in body parts, most notably the hands, feet, face, and airway passages. In addition, patients often have bouts of excruciating abdominal pain, nausea, and vomiting that is caused by swelling in the intestinal wall.
