Lingual thyroid is a rare congenital malformation that occurs more frequently in the female population. It occurs because of the error in transcriptional factors, the key for the normal differentiation of thyrocyte, so the thyroid gland tissue does not descend normally down the thyroglossal duct to the final position in the neck. Due to that, it can entirely or partially remain at the base of the tongue. This is the most frequent localization of the ectopic tissue while it can remain in the sublingual, suprahyoid and infrahyoid area as well. This disease can be diagnosed in the asymptomatic phase, as well as in the phase of compensatory and manifest hypothyroidism. In the ectopic thyroid gland, all diseases of the thyroid gland can occur as in the usual localization in the neck. The authors show a 6-year old patient, who had a routine medical examination for the inflamed throat, during which a vascular tumefaction was discovered at the base of the tongue. A cyst at the base of the tongue was suspected, but additional examination showed that it was an ectopic thyroid tissue marked as a lingual thyroid gland. Diagnosis of this disease starts with the laboratory analysis of the thyroid status. The next step involves scintigraphy of the thyroid gland with technetium-pertechnetate (99mTc) or radioactive iodine (123I). The therapy of the compensatory hypothyroidism is suppressive therapy with levothyroxine and in the manifest hypothyroidism it is hormone substitution therapy with levothyroxine. Although there are recommended age-related daily doses, they should not be accepted as final, but rather prescribed according to the individual thyroid status. .

Abstract Background Ectopic thyroid is a developmental anomaly of the thyroid gland of embryological origin. Instead of having a pretracheal situation, thyroid tissue is elsewhere, most commonly in the median cervical line along the course of the thyroglossal duct. Lingual thyroid is the most common presentation. Ectopic thyroid tissue in the submandibular region has been rarely reported. Case presentation We report herein a case of a 65-year-old man admitted to our department with a complaint of a painless swelling in the left submandibular region. Conclusions Thyroid gland ectopia should be considered among the differential diagnoses of submandibular swelling. Ectopic thyroid tissue can present with the same pathology affecting the normal thyroid gland such as malignancy and hyperthyroidism.

An ectopic thyroid gland may be present in any location along the path of migration from the foramen caecum to the mediastinum. The most common locations for an ectopic thyroid are the lingual thyroid followed by median cervical cysts. An ectopic thyroid in the submandibular region is extremely rare. We present the case of a 44-year-old patient with ectopic thyroid tissue in submandibular space and a review of the literature related to it.

Ectopic thyroid gland is a rare anomaly in the development of the thyroid gland. It is defined as any thyroid tissue that is not found on its usual topography. We present the case of a 62-year-old patient with difficulty swallowing solid food, occasional sore throat, hoarse voice, and difficulty speaking. The patient was in hypothyroid status. Thyroid scintigraphy and magnetic resonance imaging visualized a nodular mass on the base of the tongue, suprahyoid, and mediosagittal. The pathohistological finding revealed normal thyroid tissue with few colloidal changes, ruled out tumour infiltration and specific inflammatory process. She received hormonal suppression treatment as a first-line treatment. The patient showed significant improvement in symptoms with reduction of the dyspnea and the dysphagia and normalization of thyroid hormone tests.

Base Of The Tongue

Ectopic thyroid is a rare embryological aberration which can occur in any moment of the migration of the thyroid resulting in lingual (at tongue base), sublingual (below the tongue), prelaryngeal (in front of the larynx), and substernal (in the mediastinum) ectopy. It is commonly found in the base of the tongue, just behind the foramen cecum, and is subject to the same diseases as the thyroid gland itself. The thyroid gland located at the base of the tongue is called lingual thyroid. Lingual thyroid is the most frequent ectopic location of the thyroid gland, although its prevalance varies between 1:100000 and 1:300000, it occurs more frequently in females, with a female to male ratio of 4:1. The true insidence is probably underestimated due to asymptomatic lingual tyhroids. Some Authors reported having found ectopic lingual tissue in % 10 of 200 consecutive necropsies. In the literature, approximately 400 cases of symtomatic patients have been reported

Ectopic thyroid tissue has been found from the tongue to the diaphragm. Ninety percent of the reported cases of ectopic thyroid are found in the base of the tongue Total numbers of 1895 cases were included in this study. Patients were sending to CNMU-Rajshahi during the period of January’2006 to June 2009 for thyroid scanning as well as evaluation of thyroid functional status. Radio-active iodine drink / Tc99m pertachnatate I/V were given to the patients for thyroid scan. Biochemical analyses were done for the ectopic thyroid patient. Among them 17.85% patients had hypothyroidism. Only 1.5%(28) patients have diagnosed as ectopic thyroid majority of the cases had lingual thyroid (10), sub-lingual thyroid in 06, over cricoid cartilage in 05 and others were seen in sub-mandibular and sub-mental region.. This study aims to find out the incidence of ectopic thyroid tissue and its functional status. TAJ 2010; 23(1): 18-21

Increased Risk

Ectopic thyroid gland may be detected at any place between foramen caecaum and normal thyroid localization due to inadequacy of the embryological migration of the thyroid gland. It has a prevalence varying between 1/10.000 and 1/100000 in the community. Usually follow-up without treatment is preferred except for obstructive symptoms, bleeding, and suspicion of malignity. Main symptoms are dysphagia, dysphonia, bleeding, dyspnea, and obstructive sleep apnea. In symptomatic cases, the first described method in surgical treatment is open approach since it is a region difficult to have access to. However, this approach has an increased risk of morbidity and postoperative complications. Transoral robotic surgery, which is a minimally invasive surgical procedure, has advantages such as larger three-dimensional point of view and ease of manipulation due to robotic instruments. In this report, a case at the age of 49 who presented to our clinic with obstructive symptoms increasing within the last year and was found to have lingual thyroid and underwent excision of ectopic thyroid tissue by da Vinci surgical system is presented.

Dual ectopic thyroid is very rare. We report a case of dual ectopic thyroid in the lingual and infrahyoid areas in a 20-year-old female patient with no thyroid gland in its normal anatomical location. On physical examination, there was a 7 × 5 cm anterior midline neck swelling just below the hyoid bone and a 2 × 2 cm mass in the base of the tongue. Triiodothyronine (T3), thyroxine (T4), and thyroid-stimulating hormone (TSH) levels were normal. A thyroid scan with technetium-99m sodium pertechnate confirmed dual ectopic thyroid with no iodine uptake in the normal anatomical location of the thyroid gland. The infrahyoid ectopic thyroid was surgically removed for cosmetic reasons, and the lingual thyroid, which was symptomatic, was left untouched. The importance of thyroid scanning in the evaluation of anterior midline neck swellings and treatment options are discussed.

Abstract Background Ectopic thyroid tissue is a rare embryological aberration described by the occurrence of thyroid tissue at a site other than in its normal pretracheal location. Depending on the time of the disruption during embryogenesis, ectopic thyroid may occur at several positions from the base of the tongue to the thyroglossal duct. Ectopic mediastinal thyroid tissue is normally asymptomatic, but particularly after orthotopic thyroidectomy, it might turn out to be symptomatic. Symptoms are normally due to compression of adjacent structures. Case presentation We present a case of a 66-year-old male submitted to a total thyroidectomy 3 years ago, due to multinodular goiter (pathological results revealed nodular hyperplasia and no evidence of malignancy), under thyroid replacement therapy. Over the last year, he developed hoarseness, choking sensation in the chest, and shortness of breath. Thyroid markers were unremarkable. He was submitted to neck and thoracic computed tomography, magnetic resonance imaging, and radionuclide thyroid scan. Imaging results identified an anterior mediastinum solid lesion. A radionuclide thyroid scan confirmed the diagnosis of ectopic thyroid tissue. The patient refused surgery. Conclusions Ectopic thyroid tissue can occur either as the only detectable thyroid gland tissue or in addition to a normotopic thyroid gland. After a total thyroidectomy, thyroid-stimulating hormone can promote a compensatory volume growth of previously asymptomatic ectopic tissue. This can be particularly diagnosis challenging since ectopic tissue can arise as an ambiguous space-occupying lesion.

Ectopic Thyroid Tissue

<p class="abstract">An ectopic thyroid is a rare occurrence with a majority of ectopic thyroid tissue located in the lingual region or in the midline. The abnormal sites represent developmental defects in migration from the floor of the primitive foregut at the foramen caecum of the tongue to the final pre-tracheal position of the gland. A few cases of ectopic thyroid tissue have also been reported from sites seemingly unrelated to the normal development of the thyroid gland.  We report a case of ectopic thyroid in the external ear canal, which presented as a small reddish mass in the external ear canal. To the best of our knowledge, this is the first such reported case in literature and adds to the body of knowledge in such cases. Although such a finding is exceedingly rare, the authors recommend routine histopathology in all cases of polyps in the external canal and standard investigation for the status of the residual thyroid gland via isotope scans, ultrasonography or thyroid function tests.</p>
