Struma ovarii is a rare monodermal variant of ovarian teratoma that contains at least 50% thyroid tissue. Less than 8% of struma ovarii cases present with clinical and biochemical evidence of thyrotoxicosis due to ectopic production of thyroid hormone and only 5% undergo malignant transformation into a papillary thyroid carcinoma. Only isolated cases of hormonally active papillary thyroid carci...

Introduction. Thyroglossal duct cysts are developmental, epithelial lesions localized in the neck?s median line. They occur mainly children and adolescents; however, they also one-third of patients older than 20 years age. The symptoms dependent on size location along path thyroglossal duct. Case outline. This article presents a case, with diagnostic imaging surgical treatment, two-yearold girl...

It is not uncommon to encounter variations in the Thyroid gland during surgeries. Complete detailed anatomical variations in arterial and venous supply including the presence of ectopic glands is useful for diagnosis and prognosis of patients involved with thyroid disorders. With these facts we tried to evaluate the Anatomical and Morphological variations of the thyroid gland. The study was con...

Ectopic thyroid tissue is a rare entity resulting from developmental defects at early stages of thyroid gland embryogenesis, during its passage from the floor of the primitive foregut to its final pre-tracheal position. It is frequently found around the course of the thyroglossal duct or laterally in the neck, as well as in distant places such as the mediastinum and the subdiaphragmatic organs....

BACKGROUND It is difficult to explain ectopic thyroid beneath the diaphragm because during the development the thyroid descends from the tongue to the anterior of the trachea. A few cases of ectopic lesions have been reported in the literature for abdominal organs including the adrenal glands, but the mechanism by which the thyroid components migrate into the abdomen has been poorly understood....

Abstract Background In cases of papillary thyroid carcinoma (PTC), lymph nodes are a typical site metastasis. Extrathyroidal tissue involvement in differentiated causes the disease to progress and affects patients’ treatment options. Papillary (PTC) is common type (DTC), other follicular (FTC). Ectopic sites, such as intrathyroidal node invasion classical malignancy, extremely uncommon. It can ...

Ectopic thyroid tissue (ETT) is a rare entity and a challenging differential diagnosis. This is a report of a case of a mediastinal mass that was found to be an ectopic mediastinal thyroid tissue, in a 77-year-old woman who was admitted to our hospital for breast cancer management. The mediastinal mass was identified in the postsurgical computed tomography (CT) scan of the chest and was suspect...

BACKGROUND Thyroid neoplasia is common in dogs, but there are few reports of dogs with ectopic, sublingual thyroid tumors. OBJECTIVES To describe clinical features and outcomes of dogs with ectopic, sublingual thyroid neoplasia. ANIMALS Five hundred and forty-four dogs with thyroid neoplasia. METHODS This retrospective study reviewed the medical records of dogs referred for thyroid neopla...

An ectopic location of the thyroid gland usually occurs in the midline, starting anywhere from the tongue to the diaphragm. The occurrence of an ectopic thyroid gland in a non-midline site is extremely rare. We report a 32-year-old Malay woman with an aberrant thyroid gland presenting as a parapharyngeal lesion. She had a normally functioning thyroid gland. An ectopic thyroid should be consider...
