title: Urticarial vasculitis.
abstract: A case of urticarial vasculitis (UV) is presented. The pathogenesis, clinical characteristics, diagnosis, and management of this disease are reviewed, followed by clinical pearls and pitfalls for the practicing allergist (Venzor J, et al., Urticarial vasculitis, Clin Rev Allergy Immunol 23:201-216, 2002). The lesions in UV typically lasts > 24 hours in a fixed location, resolves with residual hyperpigmentation, and may or may not be pruritic. In contrast, standard urticaria lesions persist < 24 hours, leave no trace, and is always pruritic (Black AK, Urticarial vasculitis, Clin Dermatol 17:565-569, 1999). Since urticarial vasculitis is characterized by a variety of cutaneous, systemic, and serological features, different names of this disorder exist in the literature (Wisnieski JJ, Urticarial vasculitis, Curr Opin Rheumatol 12:24-31, 2000). A biopsy of an active lesion remains the gold standard for the diagnosis of urticarial vasculitis.
