Abstract:
Postmortem examination of the carcass of an approximately 10-year-old male Red-eared slider ( Trachemys scripta elegans ) was performed. The thyroid gland was enlarged, showed follicular structure, and shifted the base of the heart caudally. Histology revealed differently shaped and sized follicles in the thyroid gland. Based on the macroscopic appearance and histopathological changes of the thyroid gland, the pathological process was established as a papillary-cystic carcinoma. Neoplasia of the endocrine organs, especially of the thyroid gland, is rare in reptiles. The current case seems to be the first report of thyroid carcinoma in a Red-eared slider.

Synthesis and Regulation of Thyroid Hormones
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 iodine is then...
