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. Follow up showed excellent results with minimum patient discomfort.

Lingual thyroid should be considered in the differential diagnosis of any base of tongue mass. Examination may reveal worrisome obstructive findings. However, a majority of patients are hypothyroid and respond favorably to hormone replacement therapy upfront. Surgery is reserved for patients unresponsive to medical management or those with severe obstruction.

Lingual thyroid is a rare congenital disorder displaying ectopic thyroid tissue at the base of the tongue. This is the most common location for ectopic thyroid tissue and is usually the only thyroid tissue present. This is a case report of a 16-year-old female who presented with nasal congestion. Fiberoptic laryngoscopy showed swelling at the base of the tongue and an ultrasound examination of the neck was without visible thyroid tissue. A 99mTc-pertechnetate scintigraphy confirmed the clinical diagnosis. As the patient was euthyroid and without symptoms active surveillance was planned.

Ectopy of the thyroid gland is an abnormal embryological development. Its occurrence in children is rare. In this study, we report the case of a 12-year-old girl that presented with dysphagia and nocturnal dyspnea. Magnetic resonance imaging confirmed the presence of a lingual thyroid. Thyroid scintigraphy showed intense and elective uptake of radiotracer at the base of the tongue. Hormonal tests revealed hypothyroidism. Treatment consisted of opotherapy based on levothyroxine. Evolution has been favourable and the patient showed significant improvement with reduction of the dyspnea and the dysphagia and normalization of thyroid hormone tests.

Patients diagnosed with Lingual thyroid (LT) may have second thyroid anomaly (STA).Given rarity of dual ectopics/anomalies, standardized management recommendations are lacking. We aimed to describe our experience in management of LT with STA and suggest a management algorithm. We conducted a retrospectivechart review of patients diagnosed with LT between Jul-2013 and Dec-2019. Data regarding demographics, clinical presentation, endocrine-profile, associated STA treatment received, and outcomes were collected and analyzed. Eight patients (female-7 cases, male-1 case, adult-4 cases, children-4 cases, mean age-18.1 years, range 6-43 years) with LT were identified. Four(50%) cases had STA in addition to LT (thyroglossal cyst in two-cases, sublingual thyroid in one-case and sub-mental thyroid in one-case) and presented as neck mass. Diagnosis was confirmed with flexible-nasopharyngoscopy,ultrasonography,thyroid-scintigraphy and computed-tomography. Ectopic thyroid(s) was/were only functional thyroid gland with absence of normal thyroid in all cases. Two- cases had symptomatic for LT and were managed by coblation assisted excision of LT in one and I ablation in one-case.All adult patients were hypothyroidand received thyroxin.All pediatric cases were euthyroidand received no surgical intervention for LT.Three patients required surgery for STA; Sistrunk surgery in two and excision of submental thyroid in one. All cases were asymptomatic. These results were utilized to suggest a management algorithm for LT with STA. LT patients with STA are more symptomatic and required more surgical interventions in compare to isolated LT. When appropriate, excision of STA with/without intervention for LT and thyroxin is advocated as the treatment modality of choice in LT patients with STA.

SUMMARY
Lingual thyroid (LT) gland is the most common type of ectopic thyroid tissue, but it is an extremely rare presentation. We present a case of a 41-year-old Hispanic female patient complaining of dysphonia and dysphagia. As part of the evaluation, fiber optic flexible indirect laryngoscopy (FIL) was performed which revealed a mass at the base of the tongue. The morphological examination was highly suspicious for ectopic thyroid tissue and the diagnosis was confirmed with neck ultrasound and thyroid scintigraphy. Although the patient presented subclinical hypothyroidism, levothyroxine therapy was initiated with a favorable response which included resolution of symptoms and mass size reduction. Our case portrays how thyroid hormone replacement therapy (THRT) may lead to a reduction in the size of the ectopic tissue and improvement of symptoms, thus avoiding the need for surgical intervention which could result in profound hypothyroidism severely affecting the patients' quality of life.
LEARNING POINTS
Benign LT and malignant LT are indistinguishable clinically and radiographically for which histopathology is recommended. THRT, radioactive iodine 131 (RAI) therapy, and surgical excision are potential management options for LT. THRT may lead to size reduction of the ectopic tissue and resolution of symptoms avoiding surgical intervention.
