AbstractUrticaria 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. Along its approach, diagnostic confirmation, search for indicators of its etiopathogenesis, detection of cofactors that can modulate its activity, recognition of comorbidities, evaluation of possible biomarkers and the assessment of disease activity, impact and control are essential. The pharmacological management aims to control the symptoms, until the urticaria, which is self-resolving, is gone. This is described in a stepwise fashion with increasing complexity.
