Pathology
Classification
Thyroid malignancies can be categorised into the following key subtypes:
- primary thyroid cancers
- papillary thyroid carcinoma: 60-80% of carcinomas
- follicular thyroid carcinoma: 10-20%
- medullary thyroid carcinoma: 5%
- anaplastic thyroid carcinoma : 1-2%
-
thyroid lymphoma: ~2.5%
- primary thyroid lymphoma
- secondary thyroid involvement with lymphoma
- metastases to the thyroid: 1%
-
squamous cell carcinoma (rare) 4
- primary
- secondary
- direct invasion from head and neck squamous cell carcinoma
- metastatic disease
Risk factors
- head and neck irradiation (see radiation-induced thyroid cancer)
- family history of thyroid cancer
