"lingual thyroid"

Giacomo Sturniolo, Francesco Vermiglio, Mariacarla Moleti
Ectopy is the most common embryogenetic defect of the thyroid gland, representing between 48 and 61% of all thyroid dysgeneses. Persistence of thyroid tissue in the context of a thyroglossal duct remnant and lingual thyroid tissue are the most common defects. Although most cases of ectopic thyroid are asymptomatic, any disease affecting the thyroid may potentially involve the ectopic tissue, including malignancies. The prevalence of differentiated thyroid carcinoma in lingual thyroid and thyroglossal duct cyst is around 1% of patients affected with the above thyroid ectopies...

Lingual thyroid is defined as an ectopic thyroid gland tissue located in the midline of the tongue base and it is uncommonly observed in clinical practice and is rare in children. This paper describes the surgical treatment of ectopic thyroid at the base of the tongue in a child. The chief complaint of the 12-year-old, melanodermic female patient was the difficulty to swallow for 15 days. The intraoral physical examination barely showed a nodular lesion at tongue base. The CT scan showed a round, well defined hyperdense lesion of approximately 25...

Resistance to thyroid hormone (RTH) coexisting with ectopic thyroid is rare. Here we report a case of RTH with ectopic thyroid. A ten-year-old girl had been misdiagnosed as congenital hypothyroidism and treated with levothyroxine since she was born. Ten-year follow-up showed that the elevated thyrotropin was never suppressed by levothyroxine and no signs indicating hyperthyroidism or hypothyroidism despite elevated FT3 and FT4 levels. Therefore the girl developed no defects in physical and cognitive development...

Thyroid ectopia can occur when the process of thyroid embryogenesis fails. Here, we present the case of a 30-year-old woman with thyroid ectopia that was discovered during magnetic resonance imaging of cervical spine for referred neck pain. Imaging revealed the presence of an encapsulated mass at the base of her tongue. The patient was not symptomatic for any compression of the airways. Diagnosis of ectopic lingual thyroid was confirmed by (99m)TC scintigraphy. Incidental diagnosis of thyroid ectopia in asymptomatic adult patients is rare, and it should be considered on diagnostic imaging in case of an anterior midline cervical mass...

Ectopic thyroid is a rare developmental anomaly with lingual thyroid accounting for majority of the cases. The presence of ectopic thyroid tissue lateral to the midline is very rare, and very few cases located in the submandibular region have been reported. The simultaneous finding of submandibular ectopic thyroid tissue and a functional orthotopic thyroid gland is even rarer. In the differential diagnosis of an ectopic submandibular thyroid, it is fundamental to exclude a metastasis from well-differentiated thyroid cancer, even when primary thyroid carcinoma is not demonstrable...

The purpose of this case report is to demonstrate surgical technique of only functional but symptomatic lingual thyroid gland transposition to submandibular region by transoral approach without mandibulotomy and tongue-splitting. A 37-year-old female patient was admitted to our hospital with dysphagia and apnea symptoms. Physical examination revealed 3cm×3cm lingual thyroid gland was detected at the tongue base. The patient was euthyroid and thyroid gland was not detected in the neck. Under general anesthesia, right submandibular gland excision and transposition of lingual thyroid tissue to submandibular region with dorsal lingual artery axis flap were performed by transoral approach...

Lingual thyroid is a rare anomaly with symptoms such as upper airway obstruction, dysphagia, or hypothyroidism. However, bleeding is a very rare manifestation. This report describes a case of lingual thyroid in women with 28 weeks of amenorrhea and hematemesis, and its course of diagnosis and treatment. The pathogenesis of lingual thyroid is unknown. Although ectopic lingual thyroid is usually not managed surgically, excision of ectopic lingual thyroid can be lifesaving when it is causing bleeding or airway obstruction...

Thyroglossal duct and lingual thyroid ectopic lesions are exceedingly rare synchronous findings. Papillary thyroid carcinoma of these ectopic thyroid sites is well understood but still a rare finding. This case points to some management nuances in regard to ectopic thyroid screening with imaging and also shows the effectiveness of minimally invasive transoral robotic surgery for lingual thyroid.

Lingual thyroid is an uncommon condition, often asymptomatic. Given its benign nature, every treatment should be well balanced in terms of advantages and local morbidity. When a treatment is planned, medical and surgical therapy should be weighed against each other. Among surgical options, robotic techniques offer several advantages compared to traditional transoral procedures and external approaches, in terms of ability of resection, morbidity and quality of life. Here we present the case of a patient with tongue-base ectopic thyroid managed by means of transoral robotic surgery...

BACKGROUND: Lingual thyroid is a rare abnormality of thyroid development that is usually treated conservatively with levothyroxine replacement. Rarely, it becomes large enough to cause obstructive symptoms in the oral cavity, requiring definitive treatment. PATIENT FINDINGS: This study reports on three patients with lingual thyroid treated with radioactive iodine-131 ((131)I) with successful radioablation of their ectopic thyroid tissues. Measurement of 24-hour radioactive iodine uptake within thyroidal tissues and hybrid single-photon emission computed tomography/computed tomography imaging using either iodine-123 or technetium-99m pertechnetate scans were performed in all patients demonstrating the location and size of lingual thyroid and absence of an orthotopic thyroid gland...

OBJECTIVE: Lingual thyroid (LT) results from a developmental abnormality due to failure of the thyroid gland to descend to its pretracheal position. Given the low incidence of this disease, standardized management recommendations are lacking. We aimed to describe our institution's experience in LT management and to suggest a practice algorithm. METHODS: We conducted a retrospective review of LT diagnosed at Mayo Clinic, Rochester, Minnesota, between 1976 and 2010...

BACKGROUND: Ectopic thyroid is a rare disease. In the present study at the 9th People's Hospital in Shanghai, China, 42 patients' ectopic thyroid glands between the neck and maxillofacial region were subjected to a retrospective and transverse study based on data from 1978 to 2012 to explore the natural characteristics of ectopic thyroid. METHODS: The patients' clinical data were collected. In addition, scintigraphy (Tc-99 m, Iodine-131), CT scan, histology and pathology were performed...

A 22-year-old man presented to our department with a mass on the base of his tongue. He had a cavernous voice causing a moderate speech disorder, and he had some difficulty in swallowing. He had severe problems with sleep, associated with apnoea. In a fibreoptic laryngoscopic examination, a large 4×5 cm vascular mass was detected extending from the base of the patient's tongue to his epiglottis. It covered the epiglottis. Thyroid scintigraphy showed only thyroid tissue on the base of the tongue. Surgery was initiated transorally under the guidance of a rigid endoscope, but as the mass continued extended to the epiglottis, a transhyoid approach was taken...

Lingual thyroid is an abnormal mass of ectopic thyroid tissue seen in base of tongue caused due to embryological aberrancy in development of thyroid gland. Most of the ectopic tissue is seen in the tongue. Their identification and proper management is essential since they may be the only functioning thyroid tissue occurring in the body. We report a case of lingual thyroid in a 40 year old female patient who was hypothyroid with posterior swelling of tongue. Tc-99 scintigraphy confirmed the clinical diagnosis and surgical excision of entire tissue was done by midline mandibular split osteotomy and patient was placed under lifelong thyroxine replacement...

A 42-year-old Caucasian woman presented with a sensation of fullness in the throat and dry cough of 1-month duration. Physical examination showed a mass located in the midline of the tongue base. Cervical ultrasound confirmed the absence of thyroid gland tissue in the normal position. MRI of the neck showed a mass suggestive of lingual thyroid and scintigraphy confirmed the diagnosis. Thyroid function was normal. Despite normal thyroid function, to decrease the size of the mass and perhaps solve the problem, we decided to start levothyroxine suppression therapy...

Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures...
