Lupus eritematoso sistémico versus urticaria vasculítica hipocomplementémica: un dilema diagnóstico en la práctica clínica

Hypocomplementemic urticarial vasculitis syndrome is part of the hypocomplementemic urticarial vasculitis, occurring in patients with urticarial lesions and systemic and immune compromise, which can appear simultaneously with a connective tissue disease such as systemic lupus erythematosus or an independent disorder. The case is presented of a patient with systemic lupus erythematosus qualifying features, however, with a clinical presentation of an hypocomplementemic urticarial vasculitis syndrome. A literature review was performed in order to present the potential differences and similarities.
