抄録: Biopsy and autopsy specimens of the liver of chronic hepatitis, cirrhosis of the liver and liver cell carcinoma in the course of viral hepatitis were examined histopathologically to observe parenchymal lesions associated with liver cell carcinoma. Seventeen patients who had been initially diagnosed as chronic active hepatitis or cirrhosis of the liver by liver biopsy and finally diagnosed as liver cell carcinoma by surgical operation or post-mortem examination were studied. Several characteristic lesions of parenchymal cells of the liver were observed in chronic hepatitis and cirrhosis of the liver. The lesions were as follows: 1) liver cells showing pavement pattern, 2) atypical structural cells, 3) Anthony's liver cell dysplasia, and 4) small basophilic cells. Among the lesions, "small basophilic cells" were characteristic especially in precancerous stage of liver cell carcinoma. The size of liver cells of the lesion is relatively small, and the cytoplasm is moderately basophilic. These cells appeared, focally or in zonal pattern, at late stage of cirrhosis or chronic active hepatitis in which liver cell carcinoma eventually arised. However, it remains unclear whether "small basophilic cells" are precancerous lesion or not. Under electron microscopy, aggregation of mitochondria in perinuclear regions and proliferation of rough endoplasmic reticulum were noted. It seems that "small basophilic cells" are proliferative or regenrative cells.
