Hepatocellular dysplastic nodules.
The multistep process of hepatic carcinogenesis is mirrored by the morphologic classification of lesions detectable in cirrhosis, that include large regenerative nodules (LRN), low grade dysplastic nodules (LGDN) and high grade dysplastic nodules (HGDN). The latter belong to the "bordeline malignancy" cathegory requiring an accurate distinction from well-differentiated and early hepatocellular ...
متن کاملSpecific patterns of PIWI-interacting small noncoding RNA expression in dysplastic liver nodules and hepatocellular carcinoma
Hepatocellular carcinoma (HCC) is the result of a stepwise process, often beginning with development within a cirrhotic liver of premalignant lesions, morphologically characterized by low- (LGDN) and high-grade (HGDN) dysplastic nodules. PIWI-interacting RNAs (piRNAs) are small noncoding RNAs (sncRNAs), 23-35 nucleotide-long, exerting epigenetic and post-transcriptional regulation of gene expre...
متن کاملNonlinear tumor evolution from dysplastic nodules to hepatocellular carcinoma
Dysplastic nodules are premalignant neoplastic nodules found in explanted livers with cirrhosis. Genetic signatures of premalignant dysplastic nodules (DNs) with concurrent hepatocellular carcinoma (HCC) may provide an insight in the molecular evolution of hepatocellular carcinogenesis. We analyzed four patients with multifocal nodular lesions and cirrhotic background by whole-exome sequencing ...
متن کاملCharacterization of dysplastic nodules, early hepatocellular carcinoma and progressed hepatocellular carcinoma in cirrhosis with contrast-enhanced ultrasound.
BACKGROUND During the progression from low-grade dysplastic nodule (DN) to progressed hepatocellular carcinoma (HCC), intranodular portal tracts gradually disappear, while unpaired arteries develop increasingly. Contrast-enhanced ultrasound (CEUS) is highly accurate in depicting intranodular vascularity. This study evaluates the usefulness of CEUS in the characterization of DN, early HCC and pr...
متن کاملDISCRIMINATION OF HEPATOCELLULAR CARCINOMA FROM CIRRHOTIC NODULES BY AgNOR STAIN
Discrimination of regenerative cirrhotic nodules of the liver (CN) from hepatocellular carcinoma (HCC) is sometimes difficult. We examined the utility of AgNOR staining in this context. Fifteen cases of HCC and 25 cases of CN were stained by AgNOR method and the mean AgNOR number for one hundred nuclei in each case was determined. There was a significant difference between the mean AgNOR c...
