ABSTRACT
In this study, the Knodell histology activity index and the semi- quantitative reproducible description of the various morphological lesions of chronic hepatitis were applied on 109 liver biopsies taken from Egyptian patients infected with hepatitis C virus [HCV]. It was found that the presented histopathological features may be unusual for any of the known scoring systems. Therefore, a new system was suggested for grading and staging of liver diseases in Egyptian patients infected with HCV. Accordingly, the degrees of necro- inflammations are classified into 3 grades [1-3] and the progression of fibrosis is classified into 3 stages [1-3]. The reduced numbers of grades and stages proposed in this study may be attributed to the rapid course among Egyptians who differ in the environmental circumstances
