Pathologic Aspects of Hepatocellular Tumors

摘要: Hepatocellular tumors are pathologically divided into a limited number of entities such as focal nodular hyperplasia, hepatocellular adenoma, carcinoma and its variants, hepatoblastoma. Recent advances in immunophenotypic molecular characterization have led to an increased appreciation the complexities these growths. For example, subtypes adenomas with differing premalignant potentials been defined, our ability differentiate from high-grade dysplasia continues improve, similarities histologically discordant elements combined hepatocellular/cholangiocellular reported. This chapter describes pathologic, immunophenotypic, features tumors. Continued progress understanding growths at cellular subcellular levels suggests that categorization may continue evolve additional significant clinicopathologic correlates discovered.
