The case of a 14-year-old mongrel dog with a thyroid tumor treated by thyreoidectomy is described. The resected tumor was subjected to a detailed morphological and immunohistochemical analysis utilizing antibodies directed against thyroglobulin, calcitonin, chromogranin A, cytokeratin 19, thyroid transcription factor-1, CD31, Ki-67 and minichromosome maintenance protein 3. Expression level of the above mentioned antigens allowed to characterize the resected tumor as thyroid follicular-compact carcinoma. Common application of immunohistochemistry may increase the diagnosis precision and efficacy of thyroid tumor treatment in dogs.

Investigations have indicated that there is a correlation between thyroid nodules and patients'negative emotions. Nevertheless, the risk factors contributing to the development of negative emotions in thyroid nodule patients remain unidentified. This cross-sectional study recruited 150 patients diagnosed with thyroid nodules through ultrasound examination from January 2022 to January 2023 at Jinan Central Hospital, the Second Affiliated Hospital of Shandong First Medical University, and Qingyun County Maternal and Child Health Hospital as the case group, which were categorized based on their levels of anxiety and depression.

Background: Thyroid carcinoma (THCA) is the most common cancer of the endocrine system. Natural killer (NK) cell play an important role in tumor immune surveillance. The aim of this study was to explore the possible molecular mechanisms involved in NK cell in THCA to help the management and treatment of the disease.

Thyroid cancer (THCA) is an increasingly common malignant tumor of the endocrine system, with its incidence rising steadily in recent years. For patients who experience recurrence or metastasis, treatment options are relatively limited, and the prognosis is poor. Therefore, exploring new therapeutic strategies has become particularly urgent.

Background: With the current shift toward de-escalation of surgical management in low-risk papillary thyroid cancer (PTC), understanding predictors and the clinical significance of additional tumors in the contralateral lobe is important. This study investigated the histopathologic predictors of bilateral disease in low-risk PTC patients and the utility of preoperative ultrasonography in guiding completion thyroidectomy decisions.

Methods: Patients treated with total thyroidectomy (TT) for low-risk PTCs (< 4 cm) at the Endocrine Surgical Unit of the Royal North Shore Hospital, University of Sydney from 2013 to 2020 were identified from a prospectively maintained database.

Background And Aim: The high rate of tumor growth results in an increased need for amino acids. As solute carriers (SLC) transporters are capable of transporting different amino acids, cancer may develop as a result of these transporters' over-expression due to their complex formation with other biological molecules. Therefore, this review investigated the role of SLC transporters in the progression of cancer.
