[Significance of liver biopsy for the diagnosis of occupational liver lesions (histopathological examination)].

Report on the morphological assay of liver biopsies of 29 patients after acute or long-term influence of industrial poisons (pesticides, solvents). There were observed cytotoxic lesions with differently marked non-specific reactive hepatitis, the retrogression of which is demonstrated by repeated biopsies. As a rule a restoration took place after one year. Transitions in chronic liver diseases were not seen. It is referred to the particular importance to perform the first biopsy as much as early after the clinical discovery of such lesions of the liver.
