Lingual thyroid.

Lingual thyroid is one of the rarest anomalies of thyroid origin. It is located in the midline of the base of the tongue. Lingual thyroid répresents ectopic, i.e. accessory thyroid tissue. It develops from the epithelium of the thyroglossal duct that has not obliterated properly, and it is sometimes the only thyroid tissue. Beside two cases presented, the embryology, symptomatology, diagnostic and therapeutic procedures, the literature reports of lingual thyroid are reviewed.

[Lingual thyroid].

Lingual thyroid is a rare embryological aberration with incidence of 1:100,000. It is an ectopic thyroid tissue. In most cases, it is diagnosed in childhood and young adulthood but frequently around menopause. It appears as a mass on the base of the tongue causing mostly local symptoms often with hypothyroidism, rarely with thrive and mental retardation. Authors describe the features, diagnosis and therapy of lingual thyroid with the case of a 23-year-old woman. They analyze the probable pathomechanism and potential risk of malignant transformation of lingual thyroid. In this case, the diagnosis was described at the age of 17, but therapy or further investigation did not take place then. Six years later the patient visited our surgery with local complaints in euthyroid phase. Since the suppression therapy proved to be unsuccessful, the problem was finally solved by operation.

[The diagnosis and the treatment on lingual thyroid]

Lingual thyroid is a rare example of ectopic thyroid.This paper reported three cases of lingual thyroid(all female,aged between 16 and 61 years) were discussed with diagnosis and treatment.A transoral excision using the median total glossotomy and precervical excision was performed through a transsuprahyoid approach.Postoperative complications is not developed.The approach above mention is better than that of median labiomandibular glossotomy.

Papillary carcinoma arising in lingual thyroid.

Lingual thyroid is a well-known developmental abnormality, malignant transformation of which is rare. This is a case report of a papillary carcinoma located in ectopic lingual thyroid tissue, in a 28-year-old white male. A search of the literature revealed only one more such report.

Transposition of the lingual thyroid.

Lingual thyroid represents the only functioning thyroid tissue in the body in 70-80% of the cases, surgical ablation of which will produce hypothyroidism. Transposition of the lingual ectopic thyroid with its vasculary supply intact as a pedicle graft is presented. This seems to be the most locigal approach in preserving the viability and function of these ectopic tissues.

Ectopic lingual thyroid.

Ectopic lingual thyroid is an uncommon embryological aberration characterised by the presence of thyroid tissue located in a site other than the normal, pretracheal region. The tongue is the most frequent ectopic location of the thyroid gland; the clinical incidence of lingual thyroid varies between 1:3000 and 1:10,000. We present a new case of lingual thyroid in a 10-year-old child who presented dysphagia. The radiological findings and the biopsy confirmed the diagnosis. As the mass was well tolerated, surgery was not indicated. At this time, there are no signs of complications or malignant transformation.

Role of CO2 laser in the management of obstructive ectopic lingual thyroids.

Ectopic lingual thyroid glands may occasionally undergo massive hypertrophy and be a source of airway obstruction. Securing the airway prior to surgery in such cases may be difficult. In the present paper, we report on two cases of obstructive ectopic lingual thyroids which were successfully managed endoscopically using CO(2) laser. The use of CO(2) laser for removal of ectopic lingual thyroid tissue offers advantages over traditional surgical techniques. In our opinion, removal of an appropriate amount of gland to secure an adequate airway is all that is required in most cases.

[Dysphagia secondary to lingual thyroid].

BACKGROUND: Lingual thyroid is a rare developmental anomaly originating from aberrant embryogenesis during descent of the gland from its site of origin, the foramen caecum, to its eutopic location. OBJECTIVE: We present the case of a 30-year-old female with a history of dysphagia and pharyngeal foreign body sensation over the past 12 months, associated with hypothyroidism. METHODS: Diagnostic and therapeutic approaches are discussed. RESULTS: Diagnosis of lingual thyroid was made and transoral thyroidectomy was performed as procedure-of-choice. Microscopic analysis revealed normal thyroid tissue with abundant colloid. The patient had an uneventful recovery and was discharged 2 days after surgery. Gamma-gram with Tc99m was scheduled for postoperative follow-up. CONCLUSIONS: Transoral lingual thyroidectomy followed by life-long hormonal therapy is the appropiate approach for patients with severe symptoms due to lingual thyroid hypertrophy associated with hypothyroidism.

Hypothyroidism caused by a nonvisible lingual thyroid.

BACKGROUND: Lingual thyroid is a developmental anomaly caused by failure of migration of the thyroid gland to its normal position in the neck. This anomaly is usually manifested in childhood as hypothyroidism or local symptoms. METHODS: We present a case of a 32-year-old patient in whom lingual thyroid was diagnosed after complaints of a chronic cough. Thyroid-stimulating hormone levels were significantly elevated. Sonograms of the neck revealed atrophy of both thyroid lobes, with nonhomogeneous consistency and no lymphadenopathy. Technetium-99m scan revealed uptake at the tongue base, with no uptake at the neck or other locations. RESULTS: L-thyroxine treatment was begun, with progressive decrement in thyroid-stimulating hormone levels and cessation of the cough. CONCLUSION: This case is unique in both the advanced age of the patient and the unusual clinical presentation.

Infected ossified lingual thyroid goitre.

Lingual thyroid is a rare embryologic migration failure. It may undergo goitrous changes and the ensueing complications as well as carcinomatous transformation [1,2]. We describe a case of an infected ossified lingual thyroid goitre with suspicion of carcinomatous transformation.

Evaluation and management of the lingual thyroid gland.

Lingual thyroid gland is a rare clinical entity that is due to failure of descent of the gland anlage early in the course of embryogenesis. It may present with symptoms of dysphagia, upper airway obstruction, or even hemorrhage at any time from infancy through adulthood. We present two illustrative cases of lingual thyroid gland along with a protocol for diagnosis and management of the condition. Elements in the diagnostic and therapeutic evaluation are described with attention to the clinical findings, laboratory tests, and radiographic imaging studies employed in confirming the diagnosis and planning appropriate treatment. The natural history of the condition is reviewed and a treatment strategy is outlined that focuses on the use of suppressive doses of thyroid hormone as the initial therapy. Surgical excision of the gland is reserved for more advanced cases of gland enlargement resulting in airway compromise, severe dysphagia that limits oral intake, or ongoing hemorrhage.

[Lingual thyroid and intra-lingual thyroglossal cyst. Apropos of 2 cases].

Lingual thyroid and intra lingual thyro-glossal cyst are two benign tumours of similar embryological pathogenesis respectively with the arrest in the ectopic position of the thyroid gland during its downward migration and from abnormal persistence of the thyro-glossal tract for the cyst. The occurrence of lingual thyroid is rare 1/100,000 patients and outnumbers the incidence of intra-lingual cyst which represents an estimated 2.1% of the thyro-glossal cysts or fistulas. Both lesions are a rare cause of dysphagia and dyspnoea due to oropharyngeal obstruction, and radionuclide scintigraphy combined with CT and/or MRI will establish the diagnosis. Surgical pharyngotomy with an infra-hyoid approach provides excellent access to the lesions and complete removal of the tumours.

[A case of lingual thyroid].

A case of thyroid lingual ectopy is reported. Medical therapy was at first sufficient to control the progressive increase in thyroid volume, but adolescence and pregnancies induced a further increment in the volume of the lingual goiter, accompanied by an impairment of swallowing and respiration. Such obstructive symptoms were resolved by surgical intervention followed by continued substitutive medical therapy.
