Vasculitis and bacteraemia with Yersinia enterocolitica in late-onset systemic lupus erythematosus

We report a case of Yersinia enterocolitica 0.9 septicaemia complicating systemic lupus erythematosus in an elderly male patient. The infection gave rise to digital vasculitis, fevers and general malaise on top of pre-existing articular symptoms. Features of Yersinia septicaemia may mimic some of the signs of lupus.
