Three years ago, she was diagnosed to have non-A non-B hepatitis by liver biopsy under peritoneoscopy. Histological diagnosis was chronic active hepatitis. Her liver dysfunction unchanged during three years following-up in outpatient clinic. Then, she was readmitted for the elevated γ-globulin and anti-nuclear antibody titer. Histology showed chronic active hepatitis with bridging necrosis acompanied with occasional plasma cell aggregates. HCV antibody (Abott II) was positive, while HCV RNA was repeatedly negative.
