Histologic Features and Prevalence of Nonalcoholic Steatohepatitis (NASH). NASH is a potentially progressive type of nonalcoholic fatty liver disease (NAFLD). Panels A and B show characteristic histologic features of NASH in liver-biopsy specimens: ballooned hepatocytes (arrows), inflammatory infiltrate (arrowheads), and fibrosis. Panel C shows the relative distribution of NASH, cirrhosis, and primary liver cancer in the U.S. adult population.
