Angioedema

The answer to yesterday's medical challenge was #1 angioedema.  The patient had progressive swelling on the face and had previously had swelling of the larynx, trunk and extremities.  A diagnosis of hereditary angioedema was made from a blood test.

Angioedema just means swelling under the skin.  Spots of angioedema are called "hives" and they are usually from an allergic reaction.
