Updates to Article Attributes
Body
was changed:
Thyroidmalignancies can are most commonly primary thyroid cancers but can rarely be metastatic deposits.
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
- family history of thyroid cancer
- age <30 or >60 years
- male
- >2 cm
Staging
For primary thyroid tumours see: staging of thyroid cancer.
