Overview
Thyroid adenoma may be classified according to histology into 3 subtypes/groups: follicular adenoma, papillary adenoma, and signet cell adenoma.
Classification
- Thyroid adenomas are classified into 2 subtype: follicular adenoma and others.[1]
- Almost all thyroid adenomas are follicular adenomas.[2] Others include papillary adenoma and signet cell adenoma which are very rare.[3]
- Follicular adenomas can be described as "cold", "warm" or "hot" depending on their level of function.[4]
- Histopathologically, follicular adenomas can be classified according to their cellular architecture and relative amounts of cellularity and colloid into the following types depicted in the flowchart.
| Thyroid adenoma | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Microfollicular adenoma (fetal adenoma) | Macrofollicular adenoma (colloid adenoma) | Hürthle cell adenoma (oxyphil or oncocytic tumor) | Atypical embryonal adenoma | Hyalinizing trabecular adenoma | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
- Below is a table with the description of different types of follicular adenoma:
