Clinical diagnosis of diseases often has certain deviations, and only pathological diagnosis is reliable. Sometimes the clinical diagnosis is acute hepatitis, while the pathology suggests an acute exacerbation of chronic hepatitis; the clinical diagnosis is acute or subacute severe hepatitis, and the pathology suggests massive or submassive necrosis on the basis of cirrhosis, that is, Chronic severe hepatitis; clinically diagnosed with chronic hepatitis or virus carrier, and the pathology suggests early liver cirrhosis and so on. There are also some patients with liver damage caused by non-viral hepatitis. For example, Zhang Hongfei once analyzed 1020 cases of pediatric liver biopsy and showed that non-viral liver damage accounted for 9.6% (98 cases), of which there were as many as 18 etiologies. The top five were: a. Diseases related to lipid metabolism; b. Hepatolenticular degeneration; c. Hepatic glycogen storage disease; d. Progressive muscular dystrophy; e. Autoimmune hepatitis.
