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.

ABSTRACT Lingual thyroid is the most common presentation of ectopic thyroid tissue (ETT). It is a rare condition presents in about 1 in 100,000 populations, more commonly is seen in females. It is even rarer in children. It is mainly associated with euthyroid or hypothyroid status; hyperthyroidism is rarely seen. Its management varies from surgical excision to medical management. Here, we present a case of lingual thyroid presenting with hyperthyroidism and its management. How to cite this article Rana K, Arora N, Wadhwa V, Bhargava E.

Ectopic Thyroid Tissue

Normal anatomical location of thyroid gland is anterior to trachea and larynx. Ectopic thyroid is rare presentation. Ectopic thyroid tissue in submandibular region is even more rare. This article reports a case of five year old child who presented with swelling in left submandibular region which was later diagnosed to be an ectopic thyroid gland with no thyroid tissue in thyroid bed. Although rare, physician should consider possibility of ectopic thyroid in patient presenting with submandibular mass. Ultrasonography should always be performed to confirm presence of normal thyroid gland if surgical excision is planned.

Ectopic thyroid tissue can deposit anywhere in the body. There are several cases reporting papillary thyroid carcinoma (PTC) arising from ectopic tissues; however, these cases largely presented with primary PTC within the native thyroid gland as well. Alternatively, some cases report of PTC found solely in an ectopic thyroglossal duct cyst, but reports of isolated malignancy in other types of ectopic thyroid tissue with normal native tissue are sparse throughout the literature. Here, we present an unusual case of PTC in the midline anterior neck that does not appear to be consistent with a thyroglossal duct cyst, accompanied by a completely benign native thyroid gland, of which only few cases have been reported.

Common Location

Ectopic thyroid tissue may be found throughout the migration course of the thyroid gland. Thyroid ectopy may be partial or total. The most common location of ectopic thyroid tissue is in the tongue base (lingual thyroid). We discuss the computed tomography (CT) and radioisotope findings of a patient with ectopic lingual thyroid.

Dual Ectopic Thyroid

The presence of two ectopic foci of thyroid tissue in a single patient is an uncommon presentation. Ectopic thyroid reportedly has a low incidence. We are reporting here a case of dual ectopic thyroid present in the lingual and sub hyoid region in a 33 years old lady with short stature and hypothyroidism. Ultrasonography of the neck had revealed no thyroid gland in its normal anatomical position. The presence of ectopic thyroid tissue in the lingual and sub hyoid region were confirmed with a technetium-99m sodium per technetate thyroid scan.

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

Thyroglossal duct cysts are typically benign and usually asymptomatic. Malignant transformation is uncommon. Intralaryngeal extension is rare and results in dysphonia or dyspnea. There is no literature nowadays reporting the thyroglossal duct cyst carcinoma combining the clinical features of intralaryngeal extension. The authors present a case of progressive hoarseness and midline neck mass for 2 years. The laryngoscope and computed tomography revealed a 6-cm thyroglossal duct cyst containing ectopic thyroid tissue with intralaryngeal extension and causing airway obstruction. Complete excision with Sistrunk operation revealed papillary thyroid carcinoma. The patient resumed normal phonation after the surgery. There was no evidence of tumor recurrence and no hoarseness or dyspnea at 6 months follow up. This is the first reported case of a huge thyroglossal duct cyst carcinoma with intralaryngeal extension causing airway compromise. Complete excision of tumor is essential and vital to the symptom relief. A thyroglossal duct cyst carcinoma with endolaryngeal involvement should be considered in the differential diagnosis when the case has a massive midline neck mass with ectopic thyroid tissue and develops dyspnea or hoarseness concurrently.

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>

AbstractObjective:We report a modified surgical technique for transplanting an ectopic, lingual thyroid to the submandibular space, in order to maintain thyroid function while relieving obstructive symptoms.Case report:A 52-year-old woman complained of progressive dysphagia and dyspnoea. Ectopic lingual thyroid tissue was diagnosed. The ectopic thyroid gland was transplanted into the submandibular region via a lateral pharyngeal approach. A random muscle pedicle was prepared to provide a vascular supply to the transposed gland.Results:Twelve-month follow up confirmed the survival of the transplanted thyroid gland, with preserved thyroid function.Conclusion:Surgical transplantation of a lingual thyroid to the submandibular region offers an alternative treatment method for this anomaly, which avoids the need for resection and lifelong thyroxine replacement.
