Summary
Although pyoderma gangrenosum and leucocytoclastic vasculitis are both well‐recognised complications of rheumatoid arthritis, there have been surprisingly few reports of the two disorders occurring together. We have recently investigated two patients with this association and have demonstrated deposits of IgM, IgA, C3 and fibrinogen in the blood vessel walls of what were clinically typical pyoderma gangrenosum‐like lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
