Description

We described a 48-year-old man with a 15 year history of rheumatoid arthritis and a recent occurrence of urticarial rash. Leucocytoclastic vasculitis was detected in the dermis of the urticarial lesion. Deposition of IgM, C3 and fibrinogen was observed in the dermoepidermal junction and wall of dermal blood vessels, using immunofluorescent techniques. Laboratory studies showed elevated ESR and positive antinuclear antibody and rheumatoid factor, and the serum levels of C1q, C3, C4 and CH50 were persistently low. On the basis of these findings, urticarial vasculitis was diagnosed.
