Muscle Metastasis from Undifferentiated (Anaplastic) Thyroid Carcinoma

Solitary skull metastasis from follicular thyroid carcinoma: a case report

Introduction: Follicular thyroid carcinoma (FTC) is the second most common malignant form of thyroid cancers. FTC is more common in women with a peak incidence in the fifth and sixth decades of life. Invasion into blood vessels may lead to distant metastasis to bone, lung, liver or elsewhere. FTC rarely manifests itself as a distant metastatic lesion, especially as solitary metastasis. Case r...

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 ...

Anaplastic thyroid carcinoma

Anaplastic Thyroid Carcinoma

Thyroid cancers represent about 1% of all human cancers. Differentiate thyroid carcinomas (DTCs), papillary and follicular cancers, are the most frequent forms, instead Anaplastic Thyroid Carcinoma (ATC) is estimated to comprise 1-2% of thyroid malignancies and it accounts for 14-39% of thyroid cancer deaths. The annual incidence of ATC is about one to two cases/million, with the overall incide...

Thyroid metastasis from breast carcinoma resembling medullary thyroid carcinoma.

We are reporting a case of a 42-yr-old female with a history of right breast carcinoma. She was surgically treated (breast quadrantectomy with axillary dissection) and receiving a third cycle of adjuvant chemotherapy when a feeling of a constant pressure in the front of the neck and lack of air occurred. Subsequent work-up revealed a node in the right thyroid lobe with enlarged paratracheal bil...
