- Sixteen cases of heavy eosinophil infiltration or eosinophilic abscess of the liver in patients with gastric carcinoma were analyzed to draw attention to this interesting combination and to persue the pathogenetic mechanism. Peripheral blood eosinophilia and hepatic granuloma were found in only 5 and 4 cases, respectively.
Neither the patients' stool nor the hepatic tissues disclosed any parasitic worms or eggs, although the skin tests for Clonorchis sinensis and Paragonimus westermani were positive in 2 cases. Among stomach carcinomas, early gastric cancer tended to have more eosinophils than advanced carcinoma, but was less frequently associated with the infiltration of mast cells. In the regional lymph nodes, there was no infiltration of eosinophils even in the presence of tumor metastasis. In the liver, none of the 16 cases had metastatic gastric carcinoma and mast cells were found in only 2 cases. The results suggest that heavy hepatic infiltration of eosinophils in gastric carcinoma patients is not of the parasitic or allergic cause, but of certain eosinophil chemotactic factor which may gain access to accumulate in the liver following released from the gastric carcinoma and transfered through the portal vein.

Abstract

- To pursue a desirable format for the pathological diagnosis of liver cirrhosis, the authors attempted to classify 369 biopsy-proven cirrhosis on the basis of etiology and made effort to find out the morphological characteristics of each category. About 735 of total cases were HBsAg seropositive postnecrotic cirrhosis. Alcholic cirrhosis ws the second most frequent type, although accounted only 6.8%. In about 15%, the etiology was not known. Excluding the congenital biliary atresia, chronic biliary obstruction appeared to be a rare cause of cirrhosis among these biopsied cases. Of the HBsAg positive postnecrotic cirrhosis, the eAg seropositive cases tended to be micronodular and to show a higher necroinflammatory activity, in contrast to eAg seronegative cases and those complicated by hepatocellular carcinoma (HCC), suggesting that the loss of eAg is followed by a decrease of the destructive activity, active regeneration of hepatocytes and finally the development of HCC. alcoholic cirrhosis was micronodular in 64% and revealed histologic evidences of alcoholic liver disease in most cases. The results indicate that etiological diagnosis can be made in most cases of cirrhosis by the morphological characteristics and the precise clinical informations, including those on the NANB virus and the inborn error of metabolism, and that the pathological diagnosis should be more comprehensive, implicating the etiology, the nodular size and the necroinflammatory activity.
