[Vasculitis in rheumatoid arthritis--case report].

The presence of positive rheumatoid factor (RF) titer in a patient with rheumatoid arthritis (RA) is of clinical value because its presence tends to correlate with the development of extraarticular manifestations. There is a loose correlation with severity of disease and titer. Extraarticular manifestations includes vasculitis, pericarditis, subcutaneous nodules, pulmonary nodules or interstitial fibrosis, episcleritis and mononeuritis multiplex. The vasculitis is most frequently evidenced as skin infarctions/ulcerations and mononeuritis multiplex. We report a case of rheumatoid vasculitis in a 48 years old women with long history of RA, who developed vasculitis of distal arteries with gangrene of digits of upper and lower extremities.
