Abstract:
A 46-year-old woman was admitted to our hospital because of pain in the right upper quadrant and dyspnea. Abdominal and chest computed tomography (CT) scans revealed areas of low attenuation in both hepatic lobes, left pleural effusion, and multiple nodules in both lungs. Laboratory data indicated disseminated intravascular coagulation. She developed rapidly progressive respiratory and hepatic failure despite intensive treatment including mechanical ventilation and died of respiratory failure 3 weeks after admission. Immunohistochemical analysis of liver necropsy and cytology of the left plural effusion stained positive for factor VIII-related antigen and CD31. Based on these observations, a diagnosis of hemangioendothelioma (EHE), a rare vascular tumor, was made. A rapid clinical course and fatal outcome, as in the present case, are rare clinical manifestations in EHE.

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...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
