An Orthotopic Mouse Model of Anaplastic Thyroid Carcinoma
Published on: April 17, 2013
Abstract:
Pathological and clinical characteristics of thyroid carcinoma are reported. In 379 routine consecutive autopsies in which carcinoma was not suspected, serial sections of thyroid gland were histologically examined. Latent thyroid carcinoma was detected in 15.7% of the glands. Papillary adenocarcinoma comprised 76.3%, follicular adenocarcinoma 22.0% and trabecular carcinoma 1.7% of the cases. Sclerosing carcinoma was seen in 32 cases. The long diameter of 90% of these tumors was less than 5 mm. Whether or not thyroid carcinoma persists as such a small carcinomatous lesion indefinitely was studied along with its clinical significance. Carcinomatous lesions complicating hyperthyroidism were always less than 1 cm. About 70% were less than 5 mm long. Since proliferation of some thyroid carcinomas was inhibited by TSH suppression therapy, growth and proliferation of carcinoma in the presence of excessive thyroid hormone or hyperthyroidism is probably already inhibited.

The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
