Cutaneous sarcoidal granulomas in a patient with primary biliary cirrhosis

We report here the case of a fifty-year-old Japanese woman with a history of primary biliary cirrhosis who presented with a sarcoidal granulomatous plaque on the face. Although the occurrence of extra-hepatic granulomas and primary biliary cirrhosis has been documented, this is the first case report of cutaneous sarcoidal granulomas in the absence of demonstrable sarcoidosis occurring in a patient with primary biliary cirrhosis. Because primary biliary cirrhosis and sarcoidosis are systemic granulomatous diseases of unknown cause, the coexistence of findings compatible with both entities has led to speculation that they are related. We provide a brief review of these two diseases to help examine this hypothesis.
