Urticaria is a distinctive pattern of inflammatory response of the skin and/or mucous membranes characterized by the sudden appearance of vanishing wheals, angioedema, or both, associated with pruritus. Acute forms are frequent and limited to outbreaks of less than 6 weeks; while the chronic ones have a prevalence of less than 1%, longer duration and can be spontaneous or inducible. The etiopathogenic mechanisms involved in this disease include autoallergy, autoimmunity, and inflammation with cell activation, mainly of the mast cell, leading to its degranulation with the release of vasoactive mediators.
