Hürthle cell

large oxyphilic, eosinophilic cells found in the thyroid gland. They are metabolically altered follicular cells which accumulate large numbers of mitochondria. See also Hürthle cell tumor (below).

Hürthle cell tumor
a new growth of the thyroid gland composed wholly or predominantly of large cells (Hürthle cells) having abundant granular, eosinophilic cytoplasm. Such tumors are usually benign (Hürthle cell adenoma) but on occasion may be locally invasive or may rarely metastasize (Hürthle cell carcinoma, or malignant Hürthle cell tumor). Called also oxyphilic adenoma of thyroid gland.

Of the patients 56% were found to have papillary carcinoma (mixed type included) and 44% follicular carcinoma, including Hurthle cell carcinoma; 82% were low risk (stages I--II according to the TNM system) and 18% high risk (stages III--IV).

While PET-CT has proved itself in this clinical scenario, evidence is emerging on the advantages of PET-CT imaging in other histological types of thyroid malignancy, such as Hurthle cell, medullary, and the anaplastic variants.
We examined 56 FFPE tissue samples from follicular neoplasms for which clinical data and sufficient tissue were available [32 FA, 19 Hurthle cell carcinomas (HCC), and 10 FTC cases].
The new guidelines recommend that PET scans also may be used as part of initial staging in poorly differentiated thyroid cancers and invasive Hurthle cell carcinomas, as a prognostic tool in patients with metastatic disease to identify those patients at highest risk of rapid disease progression and disease-specific mortality, and as an evaluation of posttreatment response following systemic or local therapy of metastatic or locally invasive disease.
