title: Confronting cisternae in human hepatocellular carcinoma.
abstract: The Authors report the presence of confronting cisternae (CC) in two cases of poorly differentiated human hepatocellular carcinoma. They are interpreted as a peculiar phenotypical alteration of the tumor cells, probably related to a disturbance of the morphogenesis of nuclear and endoplasmic membranes.
