[Urticaria and Quincke's edema].

Urticaria and Quincke's edema is the most common cutaneous disease encountered in general medicine and dermatology. The symptoms are caused by vasoactive mediators released by mast cells following immunological or nonimmunological stimuli. Diagnosing the disease can be difficult, especially if the symptoms are chronically present and only barely react to treatment. Authors review the etiology, pathogenesis, special forms and treatment of acute and chronic urticaria and Quincke's edema.
