Also known as Pharyngeal Edema
Angioedema (BE: angiooedema) or Quincke's edema is the rapid swelling (edema) of the dermis, subcutaneous tissue,mucosa and submucosal tissues. It is very similar to urticaria, but urticaria, commonly known as hives, occurs in the upper dermis. The term angioneurotic oedema was used for this condition in the belief that there was nervous system involvement, but this is no longer thought to be the case.Source: Wikipedia
