Rheumatoid vasculitis remains a rare but serious complication of rheumatoid arthritis characterized by an inflammatory process that primarily affects small to medium-sized blood vessels, it can be associated with other extra-articular manifestations. A number of predictor or predisposing factors including certain human leukocyte antigen haplotypes, smoking and long-standing disease. A declining trend in the incidence of rheumatoid vasculitis has been noted since the 1990s and reconfirmed in recent studies, related to early diagnosis of rheumatoid arthritis, and widespread use of methotrexate. Rheumatoid vasculitis is associated with high rates of premature mortality with up to 40% of patients dying by 5 years, as well as a significant morbidity. We present two patients with diagnosis of rheumatoid arthritis with a chronic condition of ulcers and dysesthesias on legs associated with anemic syndrome; the histological study revealed medium size vasculitis. Treatment with inmunosuppresants and steroids was given with resolution of symptoms.

Palabras clave : rheumatoid vasculitis; rheumatoid arthritis; extra-articular manifestations.
