Quincke's disease: nonhereditary angioneurotic edema of the uvula.

We report two cases of Quincke's disease, an isolated form of angioneurotic edema involving the uvula that is induced by several factors, including foods, drugs, and inhalants. Although Quincke's disease has prominent oral manifestations, it has only rarely been described in the dental literature. The rapid onset and progression of the disorder, combined with the risk of respiratory compromise, may result in a serious medial emergency. Clinical manifestations include a nonerythematous swollen uvula, fullness in the throat, and signs of airway obstruction. A hereditary form of angioneurotic edema is associated with a biochemical defect; this must be differentiated from nonhereditary, localized forms such as Quincke's disease to determine appropriate treatment and predict prognosis. Clinical features and laboratory tests can distinguish hereditary angioneurotic edema from the nonhereditary form.
