Abstract:
A Thyroglossal cyst is a commonly encountered clinical entity resulting due to the persistence of the thyroglossal duct and the transformation of a few embryonic cells into a cyst. The incidence of malignant change in the thyroglossal cyst is reported as between 1 to 1.8 percent. Here we present a case report of a male who presented with swelling in the neck, on ultrasonography (USG) found to be a thyroglossal cyst, fine needle aspiration cytology (FNAC) suggested a papillary carcinoma within the thyroglossal cyst. Total thyroidectomy with bilateral selective neck dissection, central compartment clearance, and sistrunk operation were done. The histopathological report revealed papillary carcinoma of the thyroid within a thyroglossal cyst with neck nodal metastasis.

Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
