Abstract:
Thyroid gland angiomatoid tumors are an extremely aggressive neoplasms with varied histological patterns and features of endothelial differentiation. The histogenesis of thyroid angiomatoid tumors has been controversial for many years: these tumors may be either a variant of anaplastic carcinoma, or an angiosarcoma. We report a case of thyroid angiomatoid tumor in a 68-year-old woman. We also discuss, through a review of the literature, the pathologic criteria that could be used to distinguish between angiosarcoma and anaplastic carcinoma of the thyroid.

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...
