Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only...

It has long been known that there is a close relationship between pregnancy and the thyroid gland-iodine insufficiency, goitre development, and abnormal thyroid function are common during pregnancy. Autoimmune thyroid disease and thyrotoxicosis may also affect pregnant women, and their management requires the understanding of the interaction between the neuroendocrine and immune systems. In thi...

As part of a systematic investigation the glycosphingolipids in human tissues, acid and non-acid from thyroid parathyroid glands were isolated characterized with mass spectrometry binding carbohydrate-recognizing ligands, focus on complex compounds. The glycosphingolipid patterns very similar. major sulfatide gangliosides GM3, GD3, GD1a, GD1b, GT1b Neu5Ac-neolactotetraosylceramide, globotriaosy...

Because thyroid disease is the second most common endocrine disease affecting women of reproductive age, obstetricians often care for patients who have been previously diagnosed with alterations in thyroid gland function. In addition, both hyperthyroidism and hypothyroidism may initially manifest during pregnancy. Obstetric conditions, such as gestational trophoblastic disease or hyperemesis gr...

Metastasis to the primary thyroid carcinoma is extremely rare. We report here a case of colonic adenocarcinoma metastasis to medullary thyroid carcinoma in a 53-yr old man with a history of colon cancer. He showed a nodular lesion, suggesting malignancy in the thyroid gland, in a follow-up examination after colon cancer surgery. Fine needle aspiration biopsy (FNAB) of the thyroid gland showed t...

Despite increasing detection rates of various forms of extrapulmonary tuberculosis (TB), thyroid involvement with tubercle bacilli is rarely encountered and its imaging features have been reported in less than a handful of cases. Herein, we present the clinical, pathologic and imaging (ultrasound and CT scan) features of TB involvement of the thyroid gland in a 65-year-old woman who presented w...

BACKGROUND Papillary thyroid carcinoma presenting as isolated cervical lymphadenopathy with clinically and histologically normal thyroid gland is rarely reported. CASE REPORT We report a case of 31 years old female who presented with a left cervical mass and clinically normal thyroid gland. After inconclusive FANC, excision biopsy of her cervical lymph nodes revealed metastatic papillary thyr...

OBJECTIVES To assess the rate of thyroid gland invasion and the need for thyroidectomy in advanced laryngeal and hypopharyngeal carcinomas that require total laryngectomy. PATIENTS AND METHODS Between 1994 and 2001, 129 total laryngectomy with ipsilateral hemithyroidectomy and 14 total laryngopharyngectomy with total thyroidectomy operations were performed for primary squamous cell carcinoma ...

In the thyroid gland of mammals, except the basic follicular (F) cells, parafollicular (C) cells are detected. They belong to disperse neuroendocrine cells of the APUD system. Co-localisation of F and C cells in the thyroid gland is not accidental. It seems possible that there is an interaction between them, mediated by the peptidergic hormones. Calcitonin (CT) is proposed as an essential indic...

The thyroid gland is the largest classic endocrine organ that effects many organs of the body and plays a significant role in the process of Metabolism in animals. The aim of this study was to investigate the prevalence of thyroid disorders diagnosed by ultrasound and microscopic Lesions of the thyroid during the slaughter of apparently healthy One Humped Camels (Camelus dromedarius) in Iran.
