[Association of primary biliary liver cirrhosis with sarcoidosis--separate diseases or a new nosological entity?].

Primary biliary cirrhosis of the liver and sarcoidosis have certain clinical and histomorphological features in common. It has been inferred from this that when the two diseases occur together its assignment to the one or other is not possible and a new nosological entity is to be assumed. Two own cases are described. Both had primary biliary cirrhosis, sarcoidosis developing 12 and 13 years, respectively, after the former had been first diagnosed. The findings in this cases speak against the two diseases constituting a nosological entity.
