Introduction. Collision tumor of the thyroid gland is defined when independent and histologically distinct tumors coexist within the gland. The presence of both papillary and squamous cell carcinoma in the thyroid gland is unusual. Suggested etiologies include embryonic remanents of squamous epithelium, chronic inflammation, or thyroid malignancies promoting squamous metaplasia. Case Presentati...

We investigated thyroid function in 119 survivors of treatment for brain tumours not involving the hypothalamo-pituitary region. Cranial irradiation did not effect thyroid function but 11 of 47 children (23%) who had spinal irradiation had raised concentrations of thyroid stimulating hormone. Chemotherapy further increased the incidence of thyroid dysfunction: two of four patients who had crani...

The ectopic thyroid gland is a rare entity which is mostly found along the line of descent of the thyroid gland. Most of the patients present with midline swelling and usually seek medical attention. Dual ectopic thyroid gland is even rarer. The clinical examination and different imaging modalities establish its diagnosis. Radionuclide studies are highly sensitive and specific in demonstrating ...

Hormones are hormones secreted by the thyroid gland and their primary function is to regulate speed of metabolism in many tissues. The releases its into bloodstream response a regulating hormone released pituitary called thyroid-stimulating hormone. It only organ body that has ability synthesize iodine large quantities for use synthesis hormones. consists two lobes, joined together isthmus, loc...

The thyroid is the first endocrine gland to form during embryogenesis. At this stage, incomplete or anomalous migration of thyroid tissue causes ectopic localization of the gland. In our case, a 55-year-old woman who was evaluated via ultrasonography (USG) and multi-detector computed tomography (MDCT) had no thyroid gland at the normal location, but did have ectopic thyroid tissue in the left s...

background: the thyroid gland absorbs nearly all the iodine in the blood, independently of its isotopic composition. when a large enough activity of radioactive iodine like 131i, 132i, 133i is taken into the body, it can destroy the healthy thyroid gland cells as well as the cancer’s cells. in fact, as it is well known, some isotopes of iodine are used not only for acquiring thyroid images but ...

Tuberculosis of the thyroid gland is rare. A case of tuberculosis of the thyroid gland associated with thyrotoxicosis is reported.

The effects of irradiation on different cell compartments in the submandibular gland were analyzed in adult C57BL/6 mice exposed to X-ray irradiation and followed up for 10 days. Apoptosis was quantified using the terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-digoxigenin nick end labeling method (TUNEL). Cell proliferation was detected using immunohistochemistry for proliferating ce...
