The number of Kupffer cells was evaluated in hepatocellular carcinomas, including 18 primary lesions, 3 tumor emboli within the portal vein radicles and 4 metastatic lesions and in non-neoplastic liver adjacent to the primary lesions, to persue the origin of Kupffer cells dwelling in hepatocellular carcinoma. Hepatocellular carcinomas of the sinusoidal(trabecular) type were carefully selected, and excluded were those carcinomas which showed inflammation or other changes evoking inflammation. The immunohistochemical stains for CD 68 and lysozyme were done to identify Kupffer cells and to draw the mean Kupffer cell number per high power microscopic field of each lesion. Kupffer cell was most numerous in primary lesions followed by tumor emboli and still fewer in metastatic lesions. The Kupffer cell number in the primary lesions of hepatocellular carcinoma was in turn smaller than that of the adjacent non-neoplastic liver. The results suggest that, during the early neoplastic transformation, sinusoids of the non-neoplastic liver could creep into the carcinomatous tissue accompanying Kupffer cells.
