[A case of Sjögren's syndrome associated with chronic hepatitis C and sarcoidosis].

A 68-year-old female had been treated for chronic type C hepatitis at our department since June, 1992. In August of the same year, swelling of the right eyelid developed and she was diagnosed as having sarcoidosis on the basis of uveitis, skin lesions, and bilateral hilar lymphadenopathy (BHL) on chest X-ray. With steroid therapy, the symptom improved and BHL disappeared. In July, 2001, dryness of the mouth and dry eyes developed, and she was diagnosed as having Sjögren's syndrome (SjS). This case may be precious in discussing the pathophysiology of sarcoidosis and SjS including the association with hepatitis C virus infection.
