RESUMO
Primary joint infection caused by the Gram-negative bacteria Neisseria meningitidis is rare. Normally, joint involvement comes secondary to meningitis or severe sepsis caused by this agent. When primary arthritis is seen, monoarthritis is the most common presentation. A meningococcal polyarthritis is described in less than 10 case reports according to current literature. This case report aims to briefly review this rare clinical event in an adult woman with no previous history of rheumatological disease. Early diagnosis of polyarthritis caused by meningococcal bacteria usually present a good prognosis when properly treated.
RESUMO
The aim of the present work is to discuss the report of a patient who had simultaneous diagnosis of two rare diseases, vasculitis related to antineutrophil cytoplasmic antibodies and chronic lymphocytic leukemia. Both are diseases that may be multisystemic and thus cause diagnostic confusion. In this case, the patient had renal, pulmonary, hematological, and ocular symptoms, which could be secondary to vasculitis both as to leukemia. With the aid of imaging studies, pathological studies, immunohistochemistry and immunophenotyping, we conclude that it was a combination of the two diseases. There are other reports in literature of this association, however, with pANCA positive, this is the first report of chronic lymphocytic leukemia associated with cANCA positive vasculitis.

O presente trabalho tem por objetivo uma discussão acerca do relato de um doente que teve o diagnóstico simultâneo de duas doenças pouco frequentes, a vasculite relacionada ao anticorpo anticitoplasma de neutrófilos e a leucemia linfocítica crônica. Ambas são doenças que podem apresentar envolvimento multissistêmico e, assim, causar confusão diagnóstica. Neste caso, o doente apresentou comprometimento renal, pulmonar, hematológico e ocular, que poderiam ser secundários tanto à vasculite quanto à leucemia. Com auxílio de exames de imagem, estudos anátomopatológicos, imuno-histoquímica e imunofenotipagem concluímos tratar-se de uma associação das duas doenças. Há, na literatura, outros relatos desta associação, no entanto, com pANCA positivo; este é o primeiro relato de leucemia linfocítica crônica associada à vasculite com cANCA positivo.
