Abstract

Well-differentiated hepatocellular lesions (WDHLs) are liver tumors or nonneoplastic lesions in which the cells closely resemble normal hepatocytes. These lesions often include focal nodular hyperplasia, hepatocellular adenoma, macroregenerative nodule, dysplastic nodule, and well-differentiated hepatocellular carcinoma. The diagnosis of these lesions remains challenging because of their morphological similarities, particularly when examined using needle biopsy. The accurate diagnosis of WDHLs is crucial for patient management and prognosis. This review addresses the histopathological characteristics and diagnostic approaches of WDHLs.
