Urticaria is a sudden onset of hives with or without angioedema, it is a disease with a benign course but with a negative impact on the quality of life of patients. It is a relatively common entity, triggered by various stimuli, often recognizable with a good clinical history, however in most cases these are unknown like in chronic urticaria. Its pathophysiology is usually mediated by an immune response and treatment is symptomatic with antihistamines, however some patients have to be immune regulated.
