Race-related morphologic variations in hepatocellular carcinoma

Hepatocellular Carcinoma in Sheep

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

Hepatitis B-related hepatocellular carcinoma

Abstract Introduction Hepatocellular carcinoma is one of the most deadly cancers in the world and has been found to be prevalent in hepatitis B virus endemic regions. The association of hepatitis B virus as a major factor in the development of hepatocellular carcinoma has been observed in the past. However, the mechanisms of hepatocarcinogenesis are not fully understood. Multiple studies have s...

Prognostic molecular markers in hepatocellular carcinoma (Review article

Hepatocellular carcinoma (HCC) is the 5th commonest malignancy worldwide and is the third most common cause of cancer-related death. The prevalence is different in the world. The ability to predict patients at higher risk of recurrence and with a poor prognosis would help to guide surgical and chemotherapeutic treatment according to individual risk. As understanding of hepatocarcinogenesi...

DNA methylation of tumor suppressor genes in hepatocellular carcinoma

The basic unit of chromatin is a nucleosome included an octamer of the four core histones and 147 base pairs of DNA. Posttranslational histones modifications affect chromatin structure resulting in gene expression changes. CpG islands hypermethylation within the gene promoter regions and the deacetylation of histone proteins are the most common epigenetic modifications. The aberrant patterns of...
