"ectopic thyroid"

BACKGROUND: Thyroglossal Duct Cyst (TDC) is a common lesion of the midline neck, originating from an incomplete involution of the thyroglossal duct. It is typically observed in pre-scholar patients and surgery is the treatment of choice to prevent infections. Here reported a case of incidental diagnosis in a newborn patient. CASE PRESENTATION: a 3-week-old male baby was admitted to our hospital for weight loss and projectile vomits after breastfeeding. After a diagnosis of hypertrophic pyloric stenosis, the baby underwent pyloromyotomy...

Adrenal cysts lined by thyroid follicular epithelium are rare, with only 14 reported cases of "ectopic thyroid tissue" to date. While the primary consideration for differential diagnosis is thyroid carcinoma metastasis, exclusion of metastases is determined based on the absence of a primary thyroid lesion, serological euthyroidism, lack of thyroglobulin elevation, and absence of epithelial atypia. Herein, we report 2 cases of adrenal cysts lined by thyroid follicular epithelium. Case 1 was a 60-year-old woman with a right adrenal cyst...

Thyroid ectopy is the presence of thyroid tissue outside its normal cervical location. Clinical manifestations of thyroid ectopy are varied. The latter complications can be life-threatening. Emergency treatment is often surgical or endoscopic. We report a case of a 26-year-old man with tracheal thyroid ectopy, complicated by respiratory distress, in whom conventional treatments were not feasible. The patient was treated with radioiodine-131 administered in liquid form. The final control showed the complete resolution of the intra-tracheal mass...

Ectopic thyroid-stimulating hormone (TSH)-secreting tumors are extremely rare, with only 15 reported cases in the literature. Herein, we described a 60-year-old female patient with thyrotoxicosis and elevated or unsuppressed levels of TSH. Family history and laboratory and genetic tests did not support a diagnosis of resistance to thyroid hormone (RTH). Given the unsuppressed TSH, TSH-secreting tumor was suspected, and magnetic resonance imaging (MRI) of the pituitary gland was performed. Surprisingly, the MRI scans revealed a nodule in the nasopharynx rather than a pituitary tumor in the sella region...

OBJECTIVES: Lingual thyroid is a rare condition that affects approximately 1 in 100,000 individuals. Although it is usually detected in the pediatric population through newborn screening tests or evaluation of congenital hypothyroidism, there are cases in which it remains undetected until adulthood or until symptoms arise because of glandular enlargement. The possible symptoms of lingual thyroid include foreign body sensation in the throat, dysphagia, dyspnea, and hemorrhage. Several cases of lingual thyroid are asymptomatic and accompanied by subclinical hypothyroidism...

Lingual thyroid is a rare, abnormal ectopic thyroid tissue seen at the base of the tongue. It is a rare embryological anomaly caused by the failure of the descendence of the thyroid gland from the foramen caecum to its normal prelaryngeal area. The main aim of our study is to discuss recent advancements in the management of lingual thyroid using coblation technology. We are discussing the prospective study of 12 lingual thyroid cases that came to the government ENT hospital, Koti, in Hyderabad, from July 2016 to July 2023...

parapharyngeal space can have a mass of thyroid origin following metastasis from the thyroid or ectopic thyroid tissue. The extension of multinodular goiter into the parapharyngeal space is rare. A 54-year-old female presented with a 5-month history of neck mass and dyspnea. On examination, a large mass was seen on the right side of the neck which was bulging into the right parapharngeal. In the sonography, a large 50 × 57 mm cyst seen at the upper end of the right lobe of the thyroid...

Thyroid cancer in ectopic thyroid tissue is a very rare entity. We report a patient with papillary thyroid cancer arising from upper mediastinal ectopic thyroid tissue. The patient presented with thoracic spine metastasis with cord compression. The patient was a 67-year-old woman, who presented with upper back pain. Magnetic resonance imaging (MRI) showed suspected metastatic disease in the second and third thoracic vertebrae (T2 and T3). She underwent laminectomy and decompression surgery at the T1-T3 level...

A 67-year-old female underwent a computed tomography angiogram (CTA) of the head in the setting of acute, short-term memory loss. Two lobulated hyperattenuating lesions were incidentally discovered at the base of the tongue and the hyoid bone. Upon further investigation in the outpatient setting including further imaging and ultrasound-guided biopsy, the lesions were confirmed to be ectopic thyroid tissue with dual ectopy. Heterotopic tissue, especially when arising at separate sites, can be concerning for a broad differential diagnosis including malignancy, and further evaluation is certainly recommended...

Ectopic thyroid tissue is a rare developmental abnormality involving aberrant embryogenesis of the thyroid gland during passage from the primitive foregut to the pretracheal position. The most frequent position is the base of the tongue (lingual thyroid); however, it has been described in other sites, such as the submandibular region, trachea, mediastinum, and subdiaphragmatic regions.Here, we report a case of an adenomatous goiter that developed in mediastinal thyroid tissue without any connection to the pretracheal thyroid gland...

BACKGROUND: Follicular adenomas with papillary architecture are rare tumors of thyroid origin and are composed of completely encapsulated follicular cells with a papillary architecture lacking the nuclear characteristics of papillary carcinoma. Herein, we present a case of follicular adenoma with papillary architecture originating from an ectopic thyroid gland, diagnosed from a mass in the submandibular region. CASE PRESENTATION: A 70-year-old woman was referred to our hospital with the chief complaint of a painless left submandibular mass that had been present for one year...

Diagnosis of primary hyperparathyroidism (PHP) is based on blood assessments in terms of synchronous high calcium and PTH (parathormone), but further management, particularly parathyroid surgery that provides the disease cure in 95-99% of cases, requires an adequate localisation of the parathyroid tumour/tumours as the originating source, with ultrasound and 99m-Technetium (99m-Tc) sestamibi scintigraphy being the most widely used. We aimed to introduce an adult female case diagnosed with PHP displaying unexpected intra-operatory findings (ectopic thyroid tissue) in relation to concordant pre-operatory imaging modalities (ultrasound + dual-phase 99m-Tc pertechnetate and sestamibi scintigraphy + computed tomography) that indicated bilateral inferior parathyroid tumours...

Hemiagenesis of the thyroid gland is a rare congenital abnormality usually left unnoticed without associated thyroid disorders. The most common congenital anomaly of the thyroid gland is a thyroglossal cyst, followed by ectopic thyroid tissue and thyroid dysgenesis, which may be agenesis or hemiagenesis. Preoperative underevaluation of the thyroid hemiagenesis (THA) associated with other thyroid disorders may cause intraoperative difficulty in identifying the gland and difficulty in preservation or even identification of major neurovascular structures during neck exploration...

Thyroglobulin (TG) is a dimeric glycoprotein produced exclusively by mature thyroid tissue and stored within the follicular lumen. It is essential for the organification of iodine and the production of thyroid hormones. The concentration of TG in the bloodstream varies between individuals and depends on factors such as thyroid mass, stimulation of the gland by thyrotropin or autoantibodies, and tissue destruction. TG is essential to monitor patients with differentiated thyroid cancer; however, its use is not limited only to this clinical entity...

INTRODUCTION AND IMPORTANCE: Ectopic thyroid carcinoma often occurs in the neck, and metastatic carcinoma of the nasal cavity and sinuses is extremely rare. CASE PRESENTATION: An 11-year-old female was admitted to the hospital for one week due to nasal pain without an obvious cause and blood in the nose. A pale red mass with a peduncle at the back end of the right nasal septum was seen during the operation. Immunohistochemistry showed low-grade papillary thyroid carcinoma...

INTRODUCTION AND IMPORTANCE: The ectopic thyroid gland is a rare disease in which abnormal migration of the embryonic thyroid germ is thought to be the basis for the formation of the ectopic thyroid gland. CASE PRESENTATION: A 37 year old female sought medical attention due to feeling a sensation of swallowing foreign objects, without any other positive symptoms such as pain or difficulty breathing. Preoperative examination revealed a nodule in the left lobe of the thyroid gland and a nodule behind the left lobe...
