Portal hypertension in systemic mastocytosis
Abstract:
We report the case of a 66-year-old male patient with portal hypertension related to systemic mastocytosis. The liver was enlarged; microscopic examination showed portal mast cell infiltration and fibrosis. Portal hypertension was evidenced by splenomegaly, esophageal varices, and increased wedged-free hepatic venous pressure gradient. Arteriography showed that portal vein was patent. Portal hypertension could be the consequence of intrahepatic block due to mast cell infiltration and/or fibrosis of the liver.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
