title: Recurrent pericarditis and cardiac tamponade in a patient with hypocomplementemic urticarial vasculitis syndrome.
abstract: We describe a patient with hypocomplementemic urticarial vasculitis syndrome complicated by recurrent pericarditis and cardiac tamponade. The episodes of pericarditis were associated with urticarial vasculitis, hypocomplementemia, and circulating IgG antibodies to the collagen-like region of Clq. Histopathologic examination of the skin and pericardium demonstrated vasculitis associated with immunoglobulin and complement deposition suggesting an immune complex mediated etiology. Recurrent pericarditis should be included in the clinical spectrum of hypocomplementemic urticarial vasculitis syndrome.
