Social Welfare and Social Valueportant to distinguish secondary thyroid tumors from the primary tumors because patients who have metastasis to the thyroid have a poor prognosis in general, and most die shortly after the confirmation of distant metastasis. Immunohistochemistry is very helpful in the differential diagnosis.

Social Welfare in India and Chinain the detection of nodal metastases from differentiated thyroid carcinoma have been reported with Tg assay. However, Tg assay of FNA should not replace cytologic evaluation because of the potential of both false-positive and negative results. In addition, standardization in terms of sample collection and analysis is still lacking.

Follicular Variant of Papillary Thyroid Carcinoma,in general and also the paucity of diagnostic features of PTC in this variant, either because they are poorly developed or present only focally. When the predominant architecture is the presence of syncytial tissue fragments, especially in a background of colloid, the lesion can be misdiagnosed as nodular goiter.

Hyalinizing Trabecular Tumor,nuclear features. However, on genetic analysis, hyalinizing trabecular tumor has been shown to be a discrete entity from papillary thyroid carcinoma. Hyalinizing trabecular tumors are frequently mistaken for papillary thyroid carcinoma, medullary carcinoma, or paraganglioma, but immunohistochemical stains are helpful in resolving this.
