Nonalcoholic steatohepatitis (NASH) is liverinflammation and damage caused by a buildup of fat in the liver. It is part of a group of conditions called nonalcoholic fatty liver disease. Many people have a buildup of fat in the liver, and for most people it causes no symptoms and no problems.
The key histological features of NASH accepted by most pathologists include steatosis, hepatocellular ballooning and lobular inflammation, whereas, like in other chronic liver diseases, the presence of fibrosis is not considered a requirement for the diagnosis.he rearrangement of the intermediate filament cytoskeleton can be demonstrated by the loss of keratin 8/18 immunostaining of the cytoplasm, and may thus be evaluated in the future as a marker for the more objective detection of hepatocellular ballooning in NASH.
