Micrograph showing a (metastatic) Hürthle cell carcinoma. H&E stain.
Hürthle cell neoplasm is a rare tumour of the thyroid gland that can have a benign or malignant behaviour. They are generally considered a subset of follicular neoplasm,[1][2] which includes follicular thyroid carcinoma and follicular thyroid adenoma.
It may be referred to as oncocytic neoplasm.
Hürthle cell carcinoma and Hürthle cell adenoma redirect to here.
General
- Incidence: uncommon.
- This is a general category - includes:
- Hürthle cell adenoma.
- Hürthle cell carcinoma.
- Some advocate total thyroidectomy for all Hürthle cell neoplasms, as it is difficult to reliably differentiate adenomas and carcinomas.[3]
- It can be understood as a special type of follicular neoplasm (including follicular thyroid adenoma and follicular thyroid carcinoma).[4]
- High stage HCC has a poor prognosis.[5]
Adenoma versus carcinoma
Suggestive for carcinoma:[3]
- Male.
- >4 cm.
- Adenomas usu. <3 cm.
Definite for carcinoma:[3]
- Lymphovascular invasion.
- Capsular invasion.
Risk of malignancy by tumour size
Risk of malignancy by size - based on a series of 57 cases:[6]
| Size | Percentage malignant |
|---|---|
| <=1 cm | 17% |
| 1-4 cm | 23% |
| >4 cm | 65% |
Gross
- Yellow.
- Encapsulated.
Microscopic
Features:[4]
- Oncocytes >= 75% of cells:
- Abundant granular, eosinophilic cytoplasm.
- Round regular nucleus +/- prominent nucleolus.
- +/-Degenerative changes.
Negatives:
- Lack nuclear features of papillary thyroid carcinoma.
- Lack features of medullary thyroid carcinoma.
DDx:[7]
- Papillary thyroid carcinoma oncocytic variant.
- Medullary thyroid carcinoma oncocytic variant.
- Others.
Images
HCC - intermed. mag. (WC)
HCC - high mag. (WC)
HCC - very high mag. (WC)
HCC - very high mag. (WC)
IHC
Features:
- TTF-1 +ve (2 of 6 cases in Bejarno et al.,[8] or 6 of 6 cases in Choi et al.[9]).
- Thyroglobulin (6 of 6 cases[8]).
- CK7 (4 of 6 cases[8]).
- HBME-1 +ve (focal in 4 of 6 cases[9]).
- HCK -ve (6 of 6 cases[9]).
- CK19 +ve (focal in 4 of 6 cases[9]).
