The epithelial tumours of the thyroid are divided into benign, malignant, and C-cell categories. The malignant tumours are described under the following names: follicular carcinoma, solid and solid—follicular carcinoma, papillary carcinoma, squamous cell carcinoma, and anaplastic carcinoma. The malignant mesenchymal tumours are described as fibrosarcoma, osteosarcoma, and chondrosarcoma. There are also coexistent tumours and carcinosarcomas.
