A 33-year-old Japanese man who had suffered from liver cirrhosis due to hepatitis C virus (HCV) underwent living related liver transplantation (LRLT). The allograft was given by his brother, who was healthy with no history of hepatitis or hepatic virus infection. After LRLT, the patient's hepatitis C recurred. Liver biopsy revealed chronic viral hepatitis and no allograft rejection such as shown by portal lymphocytic infiltration or mild bridging fibrosis. Interferon and ribavirin were administered, and sustained viral response (SVR) was obtained. Although serum hepatitis B virus (HBV)-DNA/HCV-RNA polymerase chain reaction found no presence of hepatic virus, the serum examination demonstrated liver dysfunction seven months after SVR. Liver biopsies histopathologically showed portal fibrosis invading to the sinusoids, cholestasis, mild hyperplasia of the cholangioles, and no features of allograft rejection. Fibrosing cholestatic hepatitis (FCH) was diagnosed. The FCH was resistant to treatment and advanced, and the patient died 17 months post-LRLT. Several serum examinations failed to demonstrate the existence of HBV/HCV during the patient's course. FCH is a type of viral hepatitis that is characterized by recurrent viral hepatitis after allograft transplantation. Because SVR obtained by anti-viral therapy commonly resolves FCH, we believe that this patient represented a rare case of FCH. The present case suggests that not only direct viral cytotoxicity, but other factors as well, promote the development of fibrosis and cholestasis. FCH sometimes progresses irreversibly despite the absence of serum viral load. The present case informed us that immediate anti-viral therapy should be initiated when recurrent allograft viral hepatitis is diagnosed.
