Abstract
A woman with cutaneous vasculitis had a severe bullous eruption suggestive of erythema multiforme. The patient also had a history of recurrent urticaria that continued intermittently for over a yr of follow-up examination. Skin biopsy specimens of both urticarial and erythema and multiforme lesions showed leukocytoclastic vasculitis. An illness resembling systemic lupus erythematosus (SLE) is suggested by transient, lowtiter, positive antinuclear antibody tests, persistent deposits of immunoglobulin and complement in normal skin, arthralgias, circulating immune complexes and chronic hypocomplementemia. This case is similar to cases previously reported as hypocomplementemic vasculitis, an unusual SLE-related syndrome and urticaria with vasculitis.
