Abstract
-
The terms chronic active hepatitis (CAH), chronic persistent hepatitis (CPH), and
chronic lobular hepatitis (CLH) should be discontinued in favor of etiologic terminology.
The activity of necro-inflammation and the degree of fibrosis should be evaluated for
grading the severity and for the stage of disease. Members of the Korean Study Group
for the Pathology of Digestive Diseases reviewed 30 cases of chronic hepatitis and
reached the following consensus: 1) The pathology report of the biopsy samples with
features of chronic hepatitis should include the etiology, grade and stage. 2) Grade and
stage should be semiquantitatively evaluated as none, minimal, mild, moderate and
severe. 3) For grading, lobular activity and periportal activity should be evaluated,
separately. 4) To avoid confusion with other grading systems, simple report using
descriptive terms rather than numerical records is recommended in daily practice.
Criteria for each grade and stage should be presented and discussed. Histologic grading
and staging of chronic hepatitis by new standardized guidelines will give more
information about the prognosis as well as the present status of hepatitis. The terms
CAH, CPH and CLH may be used in parentheses to facilitate relearning.
