title: Changes in the small biliary passages in the hepatic localization of Hodgkin's disease.
abstract: The authors have investigated the behaviour of the small biliary passages in the liver biopsies of six patients suffering from untreated Hodgkin's disease with hepatic localization. No obstruction of the major bile ducts was demonstrated in any patient. Three of the patients were anicteric, while the three others presented with jaundice. In the first three cases typical Hodgkin's granulation tissue appears to be limited to portal tracts and collagen reaction is virtually absent. The three cases with cholestasis showed granulomatous tissue associated with heavy connective tissue rearrangement invading and dissociating the lobular structure. They also show a conspicuous bile-duct proliferation, which is not observed in the three anicteric patients. In these latter cases, however, the small bile ducts running within or near the granulomatous tissue present various morphologic changes, including basal membrane thickening, dilation or constriction of the lumen and alterations of the biliary epithelial lining. Complete disappearance of the bile duct may occur.
