Angioedema is swelling that is similar to hives, but the swelling is under the skin instead of on the surface. Hives are often called welts. They are a surface swelling. It is possible to have angioedema without hives.
This was a classic case of angioedema. Angioedema is a swelling of the deeper layers of the skin, subcutaneous tissues and the tissues immediately underlying mucous membranes, or submucosal tissue. Most cases of angioedema result from an allergic-type reaction that results in vascular leakage, which causes submucosal swelling. The lips, tongue, larynx and face are often involved. Oftentimes, foods, medications, insect bites, pollen and similar allergens can cause such a reaction.
