Idiopathic retroperitoneal fibrosis and primary biliary cirrhosis. A new association?

We encountered a case of primary biliary cirrhosis in a nonalcoholic man who had been operated on for idiopathic retroperitoneal fibrosis 20 years previously. Chronic pancreatitis was also detected on endoscopic retrograde examination. After several episodes of digestive bleeding due to ruptured esophageal varixes, the patient died of massive hemorrhage. Postmortem examination showed stage 3 primary biliary cirrhosis and a thick retroperitoneal fibrous plaque, consisting of densely fibrotic areas of collagen with rare vessels and mononuclear cells. We suggest that idiopathic retroperitoneal fibrosis may be a new autoimmune disorder associated with primary biliary cirrhosis and that primary biliary cirrhosis is a potential cause of portal hypertension, cholestasis, or both in the course of idiopathic retroperitoneal fibrosis.
