Abstract
We describe a patient with microscopic polyangiitis and primary biliary cirrhosis (PBC) who presented with a non-erosive polyarthritis followed by pulmonary and renal involvement and signs of liver disorder. Detection of pANCA and antimitochondrial antibodies with results of renal and liver biopsies allowed a diagnosis of microscopic polyangiitis and PBC. To our knowledge, this is the first report of an association between the 2 diseases.
