Intratracheal ectopic thyroid (ITET) is a rare disease, with limited cases reported in the literature. ITET is an unusual congenital abnormality and can be easily mistaken for a respiratory illness. We present a case of a 61-year-old man with a history of slight discontinuous hemoptysis for 2 years. A tracheal mass, which appeared to be connected to the left thyroid gland, was found by chest computed tomography scan. Ultrasound revealed one suspiciously malignant, solid and hypoechoic nodule in the left thyroid gland. After the thyroid origin of the mass was confirmed by bronchoscopic biopsy, the patient underwent segmental resection and anastomosis of the trachea, together with left thyroidectomy. Histopathology of the tracheal tumor showed adenomatous hyperplastic ITET, and the orthotopic left thyroid gland showed nodular goiter with atypical adenomatous hyperplasia. Clinical suspicion is warranted in patients presenting with a tracheal tumor seemingly connected to the thyroid gland, particularly in patients who have imaging features suggestive of a malignant tumor in the orthotopic thyroid but without confirmative histopathology of malignancy before surgery.

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.

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.

In spite of a considerable efficacy of conservative treatment of goiter, surgery remains the main method of treatment of such patients. Though, on the one hand, total thyroidectomy inevitably results in the development of postsurgical hypothyroidism, on the other hand – in case organ-saving surgery is performed the risk of postsurgical relapse arises. Modern morphological methods are directed to detection of oncological risk of nodular formations, and recommendations concerning an adequate volume of surgery taking into account probability of relapse are practically lacking. Therefore, the objective of the study was finding criteria of a relapsing risk by means of investigation of morphological peculiarities of the parenchymal-stromal correlations in the thyroid gland with recurrent nodular and primary nodular (multinodular) goiter without signs of functional disorders. In the course of the research according to the examined correlation parameters of the parenchyma and stroma various forms of nodular goiter were found to differ from the thyroid tissue without pathological changes by a number of parameters. In particular, specific weight of the parenchyma on an average increases reliably in the tissue of nodular goiter with its various variants in comparison with the thyroid gland without pathological changes. Together with the increase of the parenchymal specific weight in nodular goiter the amount of colloid on an average decreases, and a specific dependence on the kind of goiter is observed – colloid volume decreases from goiter with slow growth to goiter with quick growth, and it is the smallest with goiter relapse. Quantitative analysis of the goiter tissue stromal component demonstrates a considerable increase of its specific volume in comparison with normal thyroid tissue. Evaluation of changes of the morphometric parameters in the thyroid follicles found that in case of nodular goiter with slow growth the percentage of follicles with colloid is close to 100%. On an average it does not differ from that of the normal thyroid tissue. At the same time, in case of nodular goiter with quick growth the percentage of follicles with colloid decreases sharply, and in case of relapse it appears to be still less than that in nodular goiter with quick growth. Besides, with nodular goiter the diameter of follicles on an average increases in comparison with the normal thyroid tissue. In a number of cases it can be estimated as macrofollicular goiter. At the same time, the diameter of follicles is smaller in nodular goiter with quick growth. It is still less in case of goiter relapse. The size of follicles becomes sharply diverse in case of nodular goiter with slow growth, but it decreases in case of nodular goiter with quick growth and relapse. Consequently, recurrent nodular goiter is mostly similar to that of primary nodular goiter with a quick growth, though certain differences between them exist. The peculiarities found enable to suggest that nodular goiter with a quick growth possesses more chances for relapse.

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:To review the diagnosis of primary papillary carcinoma of ectopic thyroid tissue within branchial cleft cysts, and to discuss the diagnostic challenge of differentiating this condition from metastatic disease when an occult microcarcinoma is found in the thyroid gland.Methods:These comprise a case report and a literature review. We present the case of a 75-year-old woman with papillary thyroid carcinoma within the wall of a recurrent, 15 cm, lateral neck cyst.Results:Histological examination of the patient's thyroid gland found a 0.5 mm papillary thyroid microcarcinoma.Conclusion:Our differential diagnosis was primary papillary carcinoma arising from ectopic thyroid tissue, or metastatic cystic degeneration of a lateral lymph node. We make an argument for the former.

Ectopic thyroid tissue is a rare entity resulting from developmental defects at early stages of thyroid gland embryogenesis, during its passage from the floor of the primitive foregut to its final pre-tracheal position. It is frequently found around the course of the thyroglossal duct or laterally in the neck, as well as in distant places such as the mediastinum and the subdiaphragmatic organs. Although most cases are asymptomatic, symptoms related to tumor size and its relationship with surrounding tissues may also appear. Any disease affecting the thyroid gland may also involve the ectopic thyroid, including malignancy. The clinician must distinguish between ectopic thyroid and metastatic deposits emerging from an orthotopic gland, as well as other benign or malignant masses. Thyroid scintigraphy plays the most important role in diagnosing ectopy, but ultrasonography contributes as well. In cases of symptomatic disease, surgery is the treatment of choice, followed by radioiodine ablation and levothyroxine suppression therapy in more refractory cases. This review provides current understanding about the wide clinical spectrum of this rare condition, also referring to optimal diagnostic approach, differential diagnosis, and management strategies.

Ectopic thyroid tissue is seen rarely. It is often seen in cervical midline, and rarely in other areas such as submandibular area. Diagnosis is made histopathologically by fine needle biopsy after the elimination of malignancy. In the treatment of ectopic thyroid tissue, surgical excision is mostly applied. According to our knowledge, there is no exophytic thyroid tissue reported in the literature. In this paper, a 32-year-old woman who presented with a swelling under the right jaw and found a thyroid tissue attached to the normally located thyroid gland with a fibrous band in the neck was discussed.

CONTEXT: Lingual thyroid gland is a rare clinical entity that is caused by the failure of the thyroid gland to descend to a normal cervical location during embryogenesis. The occurrence of an ectopic thyroid gland located at the base of the tongue may cause problems for the patient, with symptoms of dysphagia, dysphonia, upper airway obstruction or even hemorrhage at any time from infancy through adulthood. CASE REPORT: We report on a case of lingual thyroid gland in a 41-year-old female patient. The embryology and diagnosis of ectopic thyroid are discussed and its management is outlined. Features of the diagnostic and therapeutic evaluation are described with attention to the clinical findings, laboratory tests, thyroid scan and computed tomography imaging studies employed in the confirmation of diagnosis and planning of appropriate treatment. The history of the condition is reviewed and a treatment strategy is outlined. Surgical excision of the gland is reserved for cases of gland enlargement that result in compromised airways (dysphagia or dysphonia) or recurrent hemorrhage.

Ectopic intratracheal thyroid tissue (EITT) is a rare abnormality with only limited cases reported so far. The presenting symptoms can be very similar to those of bronchial asthma. We discuss the case of a 29-year-old man with subglottic ectopic thyroid, with a history of thyroid surgery for goiter, which has been managed with laser-assisted endoscopic approach. We have also included presenting symptoms, pathophysiology, diagnosis, and management of EITT. We aim to include EITT in the differentials of airway obstruction, particularly in those patients who have goiter or previous thyroid surgeries.
