“…To date, approximately 300 cases of thyroglossal duct cyst carcinoma have been described in the English literature, mainly single case reports and small case series ( 10 ). Common histopathological types are papillary carcinoma (80%), follicular carcinoma (8%), and squamous cell carcinoma (6%), with Hurthle cell adenoma and anaplastic carcinoma as the remaining 6% ( 11 ).…”

Background: Neoplasia of ectopic thyroid components is relatively rare in thyroglossal duct cysts. We report a case of histopathologically confirmed papillary thyroid carcinoma in a thyroglossal duct cyst, discuss its clinical characteristics of, and provide reference for diagnosis and treatment.Case Description: We presented a 25-year-old female went to hospital because of "a tumor in her neck".She was preoperatively diagnosed with thyroglossal duct cyst by cervical ultrasound, and enhanced computed tomography (CT). However, the solid component of the mass suggested intracystic neoplasia. She underwent Sistrunk surgical resection, and postoperative histopathology showed thyroglossal duct cyst, and papillary thyroid carcinoma in the cyst wall. The patient had no high-risk factors and had a low risk of recurrence.After full disclosure, the patient chose close follow-up, and to date there has been no recurrence.Conclusions: There are controversies regarding the origin of thyroglossal duct cyst carcinoma and the extent of surgery required, and a lack of unified treatment guidelines. We recommend tailoring individualized treatment based on individual risk stratification. By reporting this case, we hope to inform surgeons of the various abnormalities that may occur in ectopic thyroid tissue.

“…The neural crest cells from the 4th and 5th lateral pharyngeal pouches contribute in the formation of parafollicular C cells. In the 3 following weeks, the primitive thyroid tissue descends from the foramen caecum, anterior to the hyoid bone and laryngeal cartilages, to reach its final pretracheal location, and then the diverticulum pathway retracts forming the thyroglossal duct which involutes later [1] , [2] , [7] .…”

Lateral neck ectopic thyroid tissue remains a rare entity that can be affected by any lesion involving the gland. The origin of lateral neck ectopic thyroid carcinomas still debated between a metastatic disease secondary to thyroid primary tumor and primary malignancy on the ectopic tissue. Anyway, it should indicate an exploration of the gland. We report the case of a 36 years old female with one year history of hyperthyroidism who was admitted for multinodular grade II goiter with a firm mass in the left level II of the lateral neck. The thyroid scintigraphy demonstrated multiple functioning nodules corresponding to toxic multinodular goiter; in addition to two cold hypofunctional nodules. The cervical ultrasound showed a voluminous multinodular goiter classified as EU TIRADS 5. The surgical procedure exposed a multinodular mass, lateral to the internal jugular vein, with the appearance and structure of the thyroid gland and no connection to it. The thyroid gland was exposed next through a collar incision. Each mass was dissected and removed individually. The histopathology examination of the thyroid gland found papillary carcinoma extracapsular extension. The pathology results of the other mass reported multiple colloid nodules with cystic component, papillary in appearance, with the same cancer proliferation, compatible with ectopic thyroid tissue with papillary carcinoma. No lymph node tissue was found. The patient was sent for complementary RAItherapy. We report a rare case of lateral neck ectopic thyroid papillary carcinoma that supplements and supports the lacking literature data concerning the management of this rare entity.

“…The common histopathological types are papillary carcinoma (80%), a follicular variant of papillary carcinoma (8%), and squamous cell carcinoma (6%), with the remaining 6% represented by Hurthle cell adenoma and anaplastic carcinoma [1]. Most ETC cases originate from thyroglossal duct remnants and the medial lingual thyroid [6]. This case was an ETC lacking thyroglossal duct remnants, considered to be very rare.…”

A Rare Case of 18F-FDG Uptake in an Ectopic Thyroid Carcinoma of the Anterior Middle Neck Lacking Thyroglossal Duct Remnants

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.
