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.

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 80-year old female presented with a well-defined tumor of the anterior middle neck, and a diagnosis of thyroglossal duct cyst was made. When the tumor size increased, malignancy was suspected. Ultrasonography revealed a smooth, heterogeneously hypoechoic area at her anterior neck. Contrast-enhanced computed tomography showed a well-defined contrast-enhanced tumor inferior to the hyoid bone. Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) showed a fluorine-18 fluorodeoxyglucose-avid tumor with a maximum standardized uptake value of 12.8. Surgical tumor resection was performed, and the histopathological finding was ectopic papillary carcinoma lacking thyroglossal duct remnants, which is very rare. To our knowledge, few cases of ectopic thyroid carcinoma with 18F-FDG PET/CT findings have been reported. Ectopic thyroid carcinoma lacking thyroglossal duct remnants should be considered a differential diagnosis in cases of 18F-FDG uptake in an anterior middle neck tumor.
