Ectopic thyroid tissue (ETT) lateral to the midline is rare. Its occurrence in the carotid bifurcation is exceptional. We present a 45 years woman who consulted with a slow growing right cervical swelling. Clinical examination Ultrasonography, contrast enhanced CT and cervical MRI concluded to a paraganglioma. Intra-operatively, the tumor didn't have the characteristic aspect of a paraganglioma. Complete excision was performed. Histology concluded to an ectopic micro-vesicular thyroid adenoma.Previous literature was reviewed to summarize clinical and radiologic characteristics of such rare entity...

INTRODUCTION: Ectopic thyroid tissue can be found anywhere along the embryologic path of thyroid descent. Intralaryngo-tracheal thyroid tissue is the least common site of ectopia and can present with upper airways obstruction. Its presentation in the neonate is exceptional. CASE REPORT: We describe a term female neonate with subglottic thyroid tissue causing near-total occlusion of the larynx, which led to upper airways obstruction and neonatal death. CONCLUSION: This emphasizes the importance of considering intralaryngo-tracheal tumors as a cause of acute and otherwise unexplainable respiratory distress immediately after birth...

Some patients with ectopic thyroid gland or athyreotic patients have one or more cysts in empty thyroid bed. The origin of these cysts is uncertain. We present the patient with lingual thyroid gland and small cyst in empty thyroid bed featuring the diagnostic algorithm used and discussing the possible etiologic scenarios.

Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1-3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it...

Context: Thyroid dysgenesis (TD) is the leading cause of congenital hypothyroidism (CH). The etiology of TD remains unknown in about approximately 90% of cases, the most frequent form being thyroid ectopia (TE; 48-61%). Objective: To search for new candidate genes in hypothyroid children with TE. Design/Setting/Participants: We followed a cohort of 268 TD children and performed whole-exome sequencing (WES) in three children with CH with TE (CHTE) and compared them with 18 thyroid-healthy controls...

Ectopic thyroid gland is a rare condition usually presenting with neck swelling or hypothyroidism. In most cases, ectopic thyroid tissue is the only functioning thyroid tissue, but it may rarely be associated with normal thyroid gland. Thyroiditis in an ectopic thyroid gland is very rare. Here, we describe a 13-year-old girl who was initially suspected, as a having a thyroglossal cyst. Thyroid functions were suggestive of thyrotoxicosis. She was diagnosed to have simultaneous occurrence of thyroiditis in the ectopic and eutopic thyroid glands...

During embryonic development, the abnormal migration of thyroid tissue may cause ectopic localization of the gland in the intralaryngotracheal space. This case report describes the management of a young patient with a recent diagnosis of asthma. During bronchoscopy, a large mass occupying the tracheal lumen was discovered. After tracheotomy to protect the airway, an incisional biopsy was performed and revealed an intratracheal ectopic thyroid. The deep incisions through the tracheotomy to the base of the lesion allowed colloidal content to leak out of the mass until complete resolution of airway obstruction...

The feasibility and effectiveness of transoral robotic surgery (TORS) in children with tongue base masses (TBMs) were evaluated. Eight pediatric patients who were treated with TORS for TBMs between January 2010 and January 2016 at a tertiary hospital included in the study. All pathologies were congenital lesions: four were lingual thyroglossal ductus cysts (LTGDCs), one was a minor salivary gland tumor, one was a vallecular cyst, one was a bronchogenic cyst, and one was an ectopic thyroid tissue. TORS was performed successfully in all cases...

Total thyroidectomy for substernal goiter occasionally requires a sternotomy associated with a cervical incision. We sought to analyze the postoperative complications of thyroidectomy for substernal goiters in our center and more precisely the complications related to the sternotomy. All patients who underwent total thyroidectomy for substernal goiter in our center between 2007 and 2016 were reviewed retrospectively. Patients with combined cervical incision and sternotomy (ST group, n=16) were compared to those with cervical incision alone (CT group, n=54), with regard to postoperative complications...

CASE DESCRIPTION A 7-year-old castrated male Havanese was evaluated at a veterinary teaching hospital because of a 12-week history of hyperactivity, aggression, and progressive weight loss despite a healthy appetite. CLINICAL FINDINGS Tachycardia was the only remarkable finding during physical examination. Serum 3,5,3'-triiodothyronine (T3) and free T3 concentrations were markedly increased, and thyroxine (T4), free T4, and thyroid-stimulating hormone concentrations were at or decreased from the respective reference ranges...

Ectopic thyroid is a rare congenital embryonic anomaly. Ectopic thyroid tissue can be located anywhere during its descent, but it is found primarily at the base of the tongue and in the mediastinum. It is very rarely found in the heart. Here, we report a rare case of cardiac ectopic thyroid tissue in a 53-year-old woman who presented with chest pain. Echocardiography revealed an intracardiac mass that was removed successfully. Histopathology confirmed that the mass was thyroid tissue without malignancy.

Ectopic thyroid tissue is rare and controversial. Some experts consider it to always be metastatic thyroid carcinoma, whereas others consider it benign as long as it is restricted to few follicles without cytoarchitectural features of papillary thyroid carcinoma. Immunohistochemistry (IHC) and molecular studies have not yet been performed to further characterize this entity. We retrospectively searched our pathology files for all ectopic thyroid inclusions and reviewed clinicopathologic characteristics and concurrent thyroid pathologic findings...

Ectopic thyroid tissue is a result of abnormal embryologic development and migration of the thyroid gland. It has a prevalence of one per 100,000-300,000, and the risk of malignant transformation in ectopic thyroid tissue is rare. We present a rare case of perivesical ectopic papillary thyroid carcinoma in a 76-year-old man with a normal orthotopic thyroid gland. A total thyroidectomy was performed, and the pathology report showed normal thyroid tissue with no neoplastic involvement. The patient was treated with radioactive iodine, and a control scintigraphy was without any signs of activity...

A 43-year-old otherwise healthy woman was found to have a retroperitoneal mass during a routine medical examination and was referred for further evaluation. Abdominal CT scan showed a well-delineated, low-density area that exhibited heterogeneous contrast enhancement. The area measured about 20 mm in size and was to the left of the aorta at the level of the inferior mesenteric artery. MRI showed a mass with heterogeneous hypointensity on T1 -weighted images and heterogeneous hyperintensity on T2 -weighted images...

Ectopic thyroid tissue is a rare entity and when discovered it is typically along the pathway of embryologic migration of the thyroid. We present a case of incidental finding of ectopic thyroid tissue within mediastinum in a 61-year-old female patient with a history of total thyroidectomy for thyroiditis and nodules. The patient presented to emergency room with cough and right chest pain and underwent a chest computed tomographic angiogram (CTA) to exclude pulmonary embolism as part of chest pain workup. One right paratracheal mediastinal soft tissue nodule was visualized on the images of CTA...
