It may have a heterogeneous structure in case of intratumoral hemorrhage. Doppler examination shows no circulatory signal. CEUS exploration is quite ambiguous and cannot always establish a differential diagnosis with hepatocellular carcinoma. Thus, during the arterial phase there is a centripetal and inhomogeneous enhancement.
Microscopically, the four architectural and cytological types (patterns) of hepatocellular carcinoma are: fibrolamellar, pseudoglandular , pleomorphic (giant cell), and clear cell. In well-differentiated forms, tumor cells resemble hepatocytes, form trabeculae, cords, and nests, and may contain bile pigment in the cytoplasm.
Evidence supporting a role for miR-92 in hepatocellular cancer (HCC) was derived from in situ hybridisation experiments of tumours. [1] Over expression of miR-92 was well pronounced across sex, age, virus type, clinical stage, and tumour differentiation stage, making miR-92 a potential robust biomarker for HCC.
The most frequent liver cancer, accounting for approximately 75% of all primary liver cancers, is hepatocellular carcinoma (HCC). [15] HCC is a cancer formed by liver cells, known as hepatocytes, that become malignant. In terms of cancer deaths, worldwide HCC is considered the 3rd most common cause of cancer mortalities. [16]
The Liver Imaging Reporting and Data System (aka LI-RADS) is a quality assurance tool created and trademarked by the American College of Radiology in 2011 to standardize the reporting and data collection of CT and MR imaging patients at risk for hepatocellular carcinoma (HCC), or primary cancer of the liver cells.

Multiphasic MRI is useful in diagnosing various types of liver lesions such as hepatocellular carcinoma, cholangiocarcinoma, hepatocellular adenoma, focal nodular hyperplasia, and hemangioma. [ 19 ] FibroTest (FibroSure in the USA) and FibroMax are non-invasive tests using a blood sample and an algorithm.
Grading in cancer is distinguished from staging, which is a measure of the extent to which the cancer has spread. Pathology grading systems classify the microscopic cell appearance abnormality and deviations in their rate of growth with the goal of predicting developments at tissue level (see also the 4 major histological changes in dysplasia ).
Hep G2 is an immortal cell line which was derived in 1975 from the liver tissue of a 15-year-old Caucasian male from Argentina with a well-differentiated hepatocellular carcinoma. [1] These cells are epithelial in morphology, have a modal chromosome number of 55, and are not tumorigenic in nude mice . [ 2 ]
