Nonalcoholic steatohepatitis--a histological perspective.

ABSTRACT

Nonalcoholic Steatohepatitis (NASH) is a progressive liver disease that has gained recognition in the last two decades. It may even account for some of the cases previously diagnosed as cryptogenic cirrhosis. Association of this entity,with obesity, insulin resistance and type II diabetes is well documented. In this review we clarify the terminology and describe the histological features associated with NASH. Criteria for diagnosis, grading and staging systems and role of liver biopsy is also discussed.
