Undifferentiated thyroid carcinoma.
Undifferentiated carcinoma (also known as anaplastic carcinoma) of the thyroid gland is a highly aggressive malignant neoplasm composed of undifferentiated cells that exhibit immunohistochemical or ultrastructural epithelial differentiation. Nearly all patients report a long history of thyroid gland disease, often goiter or Hashimoto thyroiditis. In most cases, there is a transformation from a ...

Palpation revealed a large, irregular, firm, tender and painless tumor mass in the right anterior neck. She was clinically euth...
متن کاملAurora B overexpression associates with the thyroid carcinoma undifferentiated phenotype and is required for thyroid carcinoma cell proliferation.
Alterations in chromosome number (aneuploidy) are common in human neoplasias. Loss of mitotic regulation is believed to induce aneuploidy in cancer cells and act as a driving force during the malignant progression. The serine/theronine protein kinases of aurora family genes play a critical role in the regulation of key cell cycle processes. Aurora B mediates chromosome segregation by ensuring o...
