[Angioedema of the oropharynx].
ABSTRACT Sudden onset of edema in the oropharynx is a potentially life threatening event. Beside adequate symptomatic therapy and also eventually prophylactic therapy, a number of potential triggers and causes have to be taken into account. Among these are allergic reactions to food, latex or insect stings, pseudoallergic reactions to certain drugs (a.o. ACE-inhibitors, NSAID), C1-esterase deficiency and other causes. The typical clinical features, the diagnostic approach and therapeutic alternatives are discussed.
