متن کاملBRAF mutations in thyroid tumors are restricted to papillary carcinomas and anaplastic or poorly differentiated carcinomas arising from papillary carcinomas.

In this study, we analyzed 320 thyroid tumors and six anaplastic carcinoma cell lines and detected BRAF mutations in 45 (38%) papillary carcinomas, two (13%) poorly-differentiated carcinomas, three (10%) anaplastic carcinomas, and five (83%) thyroid anaplastic carcinoma cell lines but not in...

متن کاملEtiopathogenesis of Differentiated Thyroid Carcinomas
INTRODUCTION Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiat...
متن کاملAdenomatous Hyperplasia Arising from Dual Ectopic Thyroid
Ectopic thyroid tissue is an uncommon embryologic aberration characterized by the presence of thyroid tissue in a site other than its usual pre-tracheal location. Single ectopic thyroid tissue is the most common variant, and the base of the tongue is the most frequent ectopic location. Dual ectopic thyroid is extremely rare, and only eleven cases have been reported in the English literature. Fu...
