The female to male ratio for Hurthle cell adenomas is 8:1, while the ratio is 2:1 for the malignant version. [6] Hürthle cell cancer tends to occur in older patients. The median age at diagnosis for Hürthle cell carcinomas is approximately 61 years old. [6] Typically a painless thyroid mass is found in patients with this type of cancer. [6]

Squamous cell tumor examples that include extensive squamous metaplasia in PTC after fine needle aspiration biopsy (FNAB) (a), squamous cell carcinoma in the thyroid of putative secondary origin (b), and squamous cell carcinoma of the esophagus metastatic in the thyroid and diagnosed by FNAB (c).
Hürthle cell neoplasm is a rare tumor of the thyroid, typically seen in women between the ages of 70 and 80 years old. When benign, it is called a Hürthle cell adenoma, and when malignant it is called a Hürthle cell carcinoma. Hürthle cell adenoma is characterized by a mass of benign Hürthle cells (Askanazy cells).

Marked atypia of type 2 pneumocytes is a characteristic finding in association with treatment with busulfan and other chemotherapeutic agents.. Atypia (from Greek, a + typos, without type; a condition of being irregular or nonstandard) [1] is a histopathologic term for a structural abnormality in a cell, i.e. it is used to describe atypical cells.
Mutations in this gene have been associated with thyroid dysgenesis, thyroid follicular carcinomas and atypical follicular thyroid adenomas. PAX8/PPARy rearrangement account for 30-40% of conventional type follicular carcinomas., [15] and less than 5% of oncocytic carcinomas (aka Hurthle-Cell Neoplasms). [16]
The cells of anaplastic thyroid cancer are highly abnormal and usually no longer resemble the original thyroid cells and have poor differentiation. ATC is an uncommon form of thyroid cancer only accounting for 1-2% of cases, but due to its high mortality, is responsible for 20-50% of deaths from thyroid cancer. [2]
Papillary thyroid cancer (magnified at right) arising within ectopic thyroid tissue of a thyroglossal cyst is a rare occurrence (less than 1% of such cysts). [ 38 ] According to Surveillance, Epidemiology, and End Results (SEER), the incidence of papillary cancer has increased from 4.8 to 14.9 per 100,000 from 1975 to 2012.
