[1] Squamous epithelial cells are not found in a normal thyroid, so the origin of SCT is not clear.

Squamous-cell carcinoma of the thyroid is biologically aggressive malignant neoplasm which is associated with rapid growth of neck mass followed by infiltration of thyroid-adjacent structures.

The tools required to diagnosis primary squamous cell carcinoma of the thyroid are panendoscopy, CT-Scan or PET-CT and immunohistological analysis.

[2] Thyroidectomy and neck dissection show good results in early stages of SCT.

Squamous-cell carcinoma of the thyroid exhibits a highly aggressive phenotype, thus prognosis of that malignancy is extremely poor.
