Successful treatment of digital tip necrosis in rheumatoid vasculitis with anti-CD20 antibody rituximab.

We report a successful treatment with rituximab in the case of rheumatoid vasculitis causing digital tips necrosis in exacerbated rheumatoid arthritis. The vasculitis lesions did not respond completely to intravenous methylprednisolone and cyclophosphamide but responded on rituximab treatment. Deep necrosis of a digital tip resolved entirely after completing a course of rituximab.
