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.

Uncommon Presentation

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.

Base Of The Tongue

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. .

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.

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.

Thyroid Screening

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.

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>
