nomously functioning thyroid nodule 505 InTROduCTIOn Diagnostic procedures for thyroid disorder include bio chemical evaluation: measurement of serum thyrotropin (TSH), free thyroid hormone (free thyroxine [FT4], free triiodothyronine [FT3]) and thyroid antibody levels, as well as imaging including ultrasonography (USG) and thyroid scan. In some cases fine needle aspiration bio psy (FNAB) shoul...

Isolated metastases to the thyroid gland are rare. It is not common for lung cancer metastasize gland, and when it metastasizes; predominant pathology usually adenocarcinoma. In this article, a rare case of metastasis from squamous cell presented. A forty-four-year-old male patient diagnosed with Stage III in our clinic. After chemotherapy, nodular lesion detected. Through fine needle aspiratio...

The occurrence of hypercholesterolemia, lowered basal metabolic rate and depressed serum proteinbound iodine in the nephrotic syndrome has directed attention to the thyroid gland in this disorder. Although hypothyroidism has been suspected, these patients are usually considered, on clinical grounds, to be euthyroid, and they fail to respond in a specific manner to even large doses of thyroid ho...

Introduction: We report a case of a 64-year old man with a history of colon carcinoma. He underwent fine-needle aspiration by CytoFoam-core and diagnosis of metastatic colon cancer to the thyroid gland. Case presentation: In this case report, a solid thyroid nodule in the right lobe of a 64-year-old male was aspirated. The cytological smears showed a small group of atypical cells with the obvi...

Thyroid follicular cell tumors arise in rodents from mutations, perturbations of thyroid and pituitary hormone status with increased stimulation of thyroid cell growth by thyroid-stimulating hormone (TSH), or a combination of the two. The only known human thyroid carcinogen is ionizing radiation. It is not known for certain whether chemicals that affect thyroid cell growth lead to human thyroid...

introduction: thyroid hormones play an important role in the regulation of metabolism, maturity and reproduction. thyroid dysfunction affects almost all endocrine glands such as pituitary and testis. the aim of this study was to investigate alterations of testosterone and luteinizing hormone (lh) serum levels as well as weights of thyroid gland and testes in methimazole (mmi)-induced hypothyroi...

salivary gland involvement is one of the radioiodine therapy complications. salivary gland scintigraphy in quantitative mode can accurately evaluate salivary gland function. methods: salivary gland scintigraphy was performed with tc-99m pertechnetate, at the time of iodine therapy as a basic study and then 3 weeks and 3 months afterwards. ejection fraction (ef) of parotid and submandibular glan...
