Primary biliary cirrhosis and systemic lupus erythematosus. A new case report.

Systemic lupus erythematosus and primary biliary cirrhosis are two autoimmune disorders that rarely occur in the same patient. Ten well-documented cases have been reported to date. We add the case of a woman who was diagnosed with systemic lupus erythematosus at 54 years of age then with primary biliary cirrhosis 18 years later. Interestingly, primary biliary cirrhosis antedated the systemic lupus erythematosus in all the other reported cases. The possibility that a patient may develop more than one autoimmune disorder should be borne in mind.
