Answer

Patients with urticarial vasculitis present with an urticarial eruption, often accompanied by a painful or burning sensation. Lesions are generalized wheals or erythematous plaques, occasionally with central clearing, lasting for more than 24 hours in a fixed location (in contrast to urticaria, which resolves in minutes to hours or migrates continually). Petechiae may be noted within the lesions, and they may resolve with ecchymoses or postinflammatory hyperpigmentation. Patients may have photosensitivity, lymphadenopathy, arthralgia, angioedema (40%), fever, abdominal pain, dyspnea, and pleural and pericardial effusions. [4] Most cases of urticarial vasculitis are idiopathic.
