title: [Pathology of alcoholic liver disease].
abstract: The history of alcohol consumption has been nearly as long as the history of mankind. Alcohol-related diseases represent a serious problem all over the world and they show a gradually increasing tendency. It can be stated that the frequency of occurrence, severity and mortality of alcohol-related hepatic diseases are in direct correlation with the amount of alcohol consumed. The direct hepatotoxic effect of alcohol and its metabolites has become obvious by now. In addition to this, other mechanisms also play a part in the development of hepatic diseases: their occurrence and severity are significantly influenced by genetic and environmental factors. The rather wide spectrum of alcohol-related hepatic diseases includes steatosis, perivenular fibrosis, alcohol-related hepatitis, occlusive venous lesions, cirrhosis and hepatocellular cancer. All of these disorders are characterized by clearly defined, characteristic but non-specific changes, which need to be supplemented by histological diagnostic criteria. Cirrhosis, which must still be regarded as an irreversibly lethal condition, is thought to develop in two ways. A well-known and widely accepted assumption is that episodes of alcohol-related hepatitis aggravated by progressive fibrosis sooner or later lead to cirrhosis. Another possible explanation is that steatosis facilitating the development and spreading of perivenular fibrosis--even without episodes of hepatitis--may lead to cirrhosis. Thus, alcohol-related hepatic conditions have characteristic pathohistological features, none of which, however, are pathognomonic at the same time. Therefore, the definitive diagnosis of any form of alcohol-related hepatic disorders needs to take evidence of alcohol consumption into account.
