Malignant Tumors of Thyroid Gland

Unusual malignant tumors of the thyroid gland.

BACKGROUND Although situated on the last places among the statistical hierarchy of human malignancies, thyroid cancers (TC) are the most common tumors of the endocrine system. Follicular epithelium neoplasms account for more than 90% of these lesions with a favourable prognosis, while resting tumors (medullary, anaplastic, lymphoma, sarcoma etc) generally present a rapid unfavorable evolution w...

MTA1 Expression in Benign and Malignant Salivary gland Tumors

Introduction: Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...

Malignant salivary gland tumors

Salivary gland neoplasms are a heterogeneous and important group of tumors of the Oral and Maxillofacial Pathology. They comprise from 2 to 3% of all the salivary gland lesions and tumors1,2 because their heterogeneity, since several years, different classifications based in clinical or microscopic criteria had been appeared.3-7 The most recent and most widely used is that proposed by Seifert e...

Neoangiogenesis in Benign and Malignant Salivary Gland Tumors

Introduction: There are few studies investigating the role of neoangiogenesis in biological behavior of salivary gland tumors. CD105 expression has demonstrated greater accuracy for detecting new vessel formation compared with other pan-endothelial molecules. This study aimed to assess and compare intratumoral Micro-Vessel Density (MVD) through using immunohistochemichal expression of CD105 bio...
