The case of a 76-year-old white woman with squamous cell carcinoma of the thyroid gland arising in a background of Hashimoto's thyroiditis is presented. Squamous cell carcinoma of the thyroid gland is a very rare and aggressive tumor, and only a few cases are reported as arising in Hashimoto's thyro

The derivation of metaplastic squamous epithelium of the thyroid gland has been the subject of a number of embryologic studies. Small foci of benign squamous epithelium may be seen as an incidental finding in surgical specimens. Rarely an entire lobe, simultaneously affected by chronic lymphocytic thyroiditis, may be diffusely infiltrated by metaplastic epithelium. This borderline squamous cell metaplasia of the human thyroid gland must be distinguished from malignancy.

## Abstract To investigate the possible relationship of HTLVβI virus infection to autoimmune thyroid disease, we examined, firstly, the frequency of HTLVβI seropositivity among patients with Hashimoto's thyroiditis and, secondly, the frequency of Hashimoto's thyroiditis in patients with HTLVβI asso
There is a recognized association between Hashimoto 's thyroiditis (HT) and thyroid neoplasms. We reviewed fine-needle aspirations (FNAs) from 90patients with HT to assess the contribution of this procedure. For seven patients, FNA showed HT and follicular neoplasm (n = 6) or HT and papillary carcin
## Abstract ## Background. Hashimoto's thyroiditis (HT) and higher levels of thyroidβstimulating hormone (TSH) have been proposed as risk factors for papillary thyroid cancer (PTC), but this issue is still being debated. The purpose of this study was whether HT was related to the risk of PTC over
