Review
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. We here review the current literature concerning primary thyroid carcinomas originating from thyroid tissue on thyroglossal duct cysts and lingual thyroid.

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 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.

Review
A case of lingual thyroid is described. This is unusual in that the entire tongue substance appears to contain thyroid tissue which is revealed graphically in the radioisotope scans. The literature is reviewed regarding the incidence and diagnosis of lingual thyroid with possible treatment options discussed.

Lingual thyroid is a rare clinical entity due to failure of the embryonic gland to descend to its normal pretracheal location. We report a case of 29 years old male patient who presented with the complaints of difficulty in swallowing and phonation. The clinical and radiology features were diagnostic of ectopic lingual thyroid. Our case report focuses on an unusual presentation of huge ectopic lingual thyroid in a male with disproportionate pressure symptoms, successfully managed surgically via suprahyoid approach.

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.
