Histopathological evaluation of liver fibrosis and cirrhosis regression

The hepatic repair complex in the setting of cirrhosis has received increasing attention, as it implies the regression of cirrhosis, which was traditionally taken to be an irreversible state. In this brief review, the patterns of fibrosis, the existing staging systems for chronic liver disease and the histopathological features of cirrhosis regression are discussed.

Liver metastasis of meningeal hemangiopericytoma: a study of 5 cases

Mesenchymal tumors in the liver, whether primary or metastatic, are rare. Meningeal hemangiopericytoma (HPC) is characteristically associated with delayed metastasis and the liver is one of the most common sites. Despite its consistent histological features, a pathological diagnosis of HPC in the liver is sometimes not straightforward due to its rarity and usually remote medical history of the primary meningeal tumor. In this report, the clinicopathological features of 5 cases of metastatic HPC to the liver were reviewed and described.
