...There are two systems for semiquantitative assessment of necroinflammatory lesions in NAFLD: NAFLD Activity Score (NAS) from the NASH CRN((128)) and Steatosis Activity Fibrosis (SAF) from the European Fatty Liver Inhibition of Progression Consortium.((129,130)) Both utilize the lesions stated above, but exact criteria and stated goals for utilization differ....

...NAFLD is characterized by macrovesicular steatosis; indeed, the presence of steatosis in at least 5% of hepatocytes is generally accepted as a definition.(9,10) Nonalcoholic steatohepatitis (NASH), a subgroup of NAFLD, deserves particular attention because of the risk for of evolution to cirrhosis....

...The diagnosis relies on an association of histological features and a consensus exists on the main elementary features that are commonly observed in NASH (ballooning/clarification, inflammation, perisinusoidal fibrosis, predominance of lesions in zone 3).(10,12)....

...The histological check-list was from the NASH-CRN with few additional comments.(10) Among major features, ballooning was graded from 0 to 2 (0: normal hepatocytes with cuboidal shape and pink eosinophilic cytoplasm; 1: presence of clusters of hepatocytes with a rounded shape and pale cytoplasm usually reticulated....

...Although the likelihood of NASH increases with NAS, there exists a wide gray zone (NAS 3-4) where NASH may or may not be present.(10) Therefore, the aims of our study were to devise an algorithm for categorization of obesity-associated liver diseases, to apply this algorithm to a large population of morbidly obese patients so as to assess the prevalence of liver lesions in a well-defined group of obese undergoing bariatric surgery, to validate the algorithm in a series of biopsies in patients with metabolic syndrome without morbid obesity, and to make new proposals regarding the scoring of obesity-associated liver diseases....

...Indeed, liver cell ballooning/clarification is among the most difficult lesions to consistently identify and grade among pathologists.(10) In the present study, we added references to the shape and size of adjacent normal hepatocytes in order to complement the current definition; this should help to better recognize and semiquantify this feature....

...Based on a seminal article, the definition included steatosis, ballooning, mixed acute and chronic lobular inflammation, and zone 3 perisinusoidal fibrosis.(12) More recently, the NASH-CRN stated that NASH was ‘‘established by the presence of a characteristic pattern of steatosis, inflammation and hepatocellular ballooning on liver biopsies in the absence of significant alcohol consumption,’’ thereby eliminating sinusoidal fibrosis from the definition....
