General description
Difficulties in the diagnosis of thyroid lesions, even with histologic analysis, are well recognized. Diagnostic discrepancies in follicular thyroid carcinoma and papillary carcinoma have been considered to be a challenge among pathologists for a long time. These diagnostic challenges have inspired clinical research interests in novel methods of correctly identifying thyroid lesions. Thyroid peroxidase (TPO) is a thyroid-specific enzyme involved in the synthesis of thyroid hormone. TPO can be detected in formalin-fixed, paraffin-embedded tissues of normal thyroid, thyroid carcinoma of papillary and follicular type. Depending on different series of studies, the sensitivity of TPO for carcinoma of the thyroid has been reported between 44% and 100%, while specificity ranges between 68% and 100%. Studies indicate that anti-thyroid peroxidase, anti-HBME-1, anti-galectin-3, and anti-CK19, together may form a useful immunohistochemical panel for identification of thyroid carcinoma of papillary and follicular types.

We evaluated the interobserver and intraobserver reproducibility in the histopathology of follicular thyroid carcinoma (FTC). Forty-one anonymous FTC pathology slides were independently reviewed by 5 pathologists, and 31 of them were also evaluated twice by the same pathologist. A final

We evaluated some proposed molecular thyroid tumor markers: thyroid peroxidase (TPO), galectin-3, cytokeratin-19, and HBME-1, individually and in combination, by immunohistochemistry in a total of 242 archival thyroid tissue sections. The expression of each individual marker was most helpful for

In this retrospective histologic study, galectin-3 had a sensitivity of 92% (22/24) for papillary thyroid carcinoma and 44% (4/9) for follicular thyroid carcinoma. Thyroid peroxidase (TPO) had a sensitivity of 50% (12/24) for papillary and 11% (1/11) for follicular carcinoma.

Cold thyroid nodules are common, in particular in iodine-deficient areas, but only a minority of them are malignant requiring surgery. Thyroid peroxidase (TPO) immunostaining of fine-needle aspiration cytology (FNAC) material has proven helpful in diagnosing cells from malignant lesions, but

Although histologic definition of follicular thyroid lesions is readily available, application of the diagnostic criteria and personal experience may lead to disagreement among pathologists. To investigate interobserver variation in assessment of encapsulated follicular lesions, eight pathologists (four American and four
