Abstract

Large-cell change of hepatocytes (LCC), also called liver cell dysplasia of large-cell type, is a set of cytologic changes comprising nuclear and cytoplasmic enlargement, nuclear pleomorphism, and multinucleation. This entity is encountered frequently on histologic or cytologic examination of specimens obtained from livers with a variety of chronic diseases and originally was thought to have a premalignant nature. Accumulating evidence, however, now suggests that LCC is merely a reactive change. Having often observed LCC in liver specimens with chronic biliary tract disease, that is, in livers where cholestasis preceded hepatocyte injury, we surmised that LCC may be a result of prolonged cholestasis. To determine whether there was any association between LCC and cholestasis, we examined microscopically a series of 400 nodules from 40 consecutive adult cirrhotic livers, resected on transplantation, and graded LCC and cholestasis semiquantitatively. LCC was present diffusely in cirrhotic nodules of 25 specimens (62.5%). Nine additional specimens (22.5%) had focal mild LCC. Usually, LCC and cholestasis occurred together, in the same cirrhotic nodules and in the same areas of nodules. There was a statistically significant association between the presence and grade of LCC and those of cholestasis (p < 0.0001; chi-square test). Within etiological categories of cirrhosis (chronic hepatitis; n = 28; alcoholic liver disease; n = 6; biliary disease: n = 6), the significance was maintained. We conclude that, in cirrhosis of different etiologies, LCC may represent a reactive change that results from prolonged cytoplasmic cholestasis.
