RESUMO
Background: Midline developmental neck lesions primarily consist of thyroglossal duct remnants. Their recurrence is uncommon following thorough resection, which includes hyoid removal (the Sistrunk procedure). Case report: A 3-year-old girl presented with mucoid secretion drainage and swelling in the anterior mid-neck region, clinically resembling a thyroglossal duct remnant. Following an initial Sistrunk procedure, the lesion recurred, prompting a subsequent resection. Histological analysis revealed a mucocele alongside acinar and mucous ectopic salivary glands. Conclusions: The ectopic salivary gland can manifest along the midline of the neck and may clinically resemble the signs and symptoms of a thyroglossal duct cyst. Importantly, it can exhibit recurrence post-surgery, even following hyoid resection.

Sistrunk procedure for thyroglossal duct cyst (TGDC) includes removal of the thyroglossal cyst, middle portion of the hyoid bone and the tract towards the foramen caecum. Endoscopic approaches have surpassed the traditional open approaches for the treatment of benign thyroid swellings and TGDCs. Endoscopic Sistrunk procedure using bilateral axillo-breast approach is a safe and better alternative for the successful treatment of TGDC and provides excellent cosmetic results.
RESUMO
OBJECTIVES: To evaluate the long-term efficacy and safety of ethanol ablation (EA) for the treatment of thyroglossal duct cysts (TGDCs). METHODS: This retrospective study included 81 consecutive patients diagnosed with and treated for symptomatic TGDCs at two institutions between Jan 2008 and Oct 2018. Preprocedural evaluation included US assessment with calculation of the TGDC volume. EA was performed under US guidance using 99% ethanol. Post-treatment follow-up was scheduled within 3 months, 6 months, and then annually. Immediate success was defined as a volume reduction ratio (VRR; ratio of the volume difference after EA to the initial TGDC volume) > 50% within 3 months. Long-term success was defined as VRR > 50% or resolution or improvement of cosmetic problems and symptoms without recurrence at last follow-up. RESULTS: Seventy-seven patients underwent EA, and outcomes were assessed in 68 patients with available follow-up data. The immediate success rate of the first EA was 81% (55/68), with a mean VRR within 3 months of 73% ± 31%. One patient (1.5%, 1/68) developed wound inflammation after the first EA. Forty-two patients were followed up for longer than 2 years. For the median follow-up of 69 months (range, 24-131 months), the long-term success rate was 83% (35/42), with a mean VRR at last follow-up of 81% ± 35%. No patients developed malignancy from the ablated TGDCs. CONCLUSIONS: EA for treatment of TGDCs achieved acceptable rates of immediate and long-term efficacy with a low complication rate, and can be considered as a first-line treatment for the management of TGDCs. KEY POINTS: ⢠The immediate success rate of EA for the treatment of TGDCs was 81% (55/68), with a mean VRR within 3 months of 73% ± 31%. ⢠For the median follow-up of 69 months (range, 24-131 months), the long-term success rate was 83% (35/42), with a mean VRR at last follow-up of 81% ± 35%. ⢠No patients developed malignancy from the ablated TGDCs but one patient (1.5%, 1/68) developed wound inflammation after the first EA.

OBJECTIVES: To review the effectiveness and safety of chemical ablation using ethanol or OK-432 for the treatment of TGDCs (thyroglossal duct cysts). METHODS: MEDLINE and EMBASE databases were searched up to May 29, 2020, to identify studies reporting the safety and efficacy of chemical ablation using ethanol or OK-432 for the treatment of TGDCs. The search query consisted of synonyms of thyroglossal duct cysts and ethanol or OK-432 ablation. The pooled success and complication rates were calculated using the inverse variance method to calculate weights, and pooled proportions were determined using the DerSimonian-Laird random-effects method. RESULTS: Seven original articles including a total of 129 patients were included. The efficacy of chemical ablation was acceptable, with a pooled success rate of 70% (95% CI, 47-86%). The pooled success rate of ethanol ablation was superior to that of OK-432 ablation, although with equivocal statistical significance (84% vs. 51%, p = 0.055). Repeat ethanol ablation achieved a pooled success rate of 47% (95% CI, 24-71%). The chemical ablation procedures were safe, with a pooled major complication rate of 0.9% (95% CI, 0.1-5.8%). CONCLUSIONS: Chemical ablation using ethanol or OK-432 for the treatment of TGDCs had acceptable success and low complication rates, and repeat treatment after initial failure was also feasible. In addition, it is an inexpensive and simple procedure and could therefore be considered a first-line treatment for TGDCs. KEY POINTS: ⢠The efficacy of chemical ablation using ethanol or OK-432 was acceptable, with a pooled success rate of 70% (95% CI, 47-86%). The pooled success rate of ethanol ablation was superior to that of OK-432 ablation, although with equivocal statistical significance (84% vs. 51%, p = 0.055). ⢠Repeat ethanol ablation was also feasible, with a pooled success rate of 47% (95% CI, 24-71%). ⢠The chemical ablation procedures were safe, with a pooled major complication rate of 0.9% (95% CI, 0.1-5.8%).

Thyroglossal cyst is the most common congenital neck anomaly in children with equal sex incidence, but papillary carcinoma of the thyroglossal cyst in children is rare with only 10 cases reported so far. Even in adults, the incidence of malignancy in the thyroglossal cyst is only 1%. Most cases are diagnosed following surgery on histopathological examination; there is no consensus on the management owing to this rarity and indolent but unpredictable behavior of thyroid cancers. Here, we present one such rare case.
RESUMO
PURPOSE: The optimal management of thyroglossal cyst carcinoma, particularly the extent of surgery required is controversial. The aim of this study was to evaluate the need for routinely adding total thyroidectomy to Sistrunk's operation in the management of this condition. METHODS: The clinical records of 19 patients with a diagnosis of thyroglossal cyst carcinoma encountered in an 11-year period (2004-2015) were reviewed. All patients underwent total thyroidectomy in addition to Sistrunk's procedure. The rate of concomitant thyroglossal cyst and thyroid carcinomas was calculated and cancers were staged according to the AJCC-TNM staging system. Patients were divided into two groups: those with thyroglossal cyst carcinoma only (group A) and those with a synchronous or metachronous thyroid carcinoma as well (group B). The need for radioactive iodine ablation in group A was assessed. The ability to omit total thyroidectomy based on thyroglossal cancer size and a negative thyroid ultrasound was also evaluated. RESULTS: The rate of concomitant thyroid cancer was 63.2 % (12/19). Based on stage, three out of the seven patients in group A required radioactive iodine ablation. Total thyroidectomy was ultimately justifiable in 78.9 % (15/19) of cases. Omitting total thyroidectomy in T1 thyroglossal cyst cancers or based on a sonographically normal thyroid was associated with a 43 % risk of missing thyroid malignancy. CONCLUSION: The routine addition of total thyroidectomy to Sistrunk's procedure seems to be appropriate for comprehensive loco-regional control especially that selecting a subset of patients in which it could be omitted is a difficult task.

A 2-month-old full-term female infant developed nasal stridor, which progressed to respiratory distress and poor sucking ability. Direct pharyngoscopy showed laryngomalacia and a midline cystic mass in the lingual region. The mass pressed on the epiglottis, causing dyspnea. Computed tomography incidentally revealed extralobar pulmonary sequestration. Direct deroofing of the lingual cyst and plication of the epiglottis were performed at 3 months of age, and the patient recovered from the respiratory distress. Histopathology of the cystic mass showed a thyroglossal duct cyst. Thoracoscopic resection of the pulmonary sequestration was then done at 17 months of age. Thyroglossal duct cysts in the lingual region may cause destabilization of the epiglottis and laryngomalacia, resulting in acquired respiratory obstruction. The combination of thyroglossal duct cyst, laryngomalacia, and pulmonary sequestration is rare; therefore, reports must be accumulated in order to explore the embryological origins of such cases.

INTRODUCTION: In spite of being inaccurate in terms of suprahyoid dissection, Sistrunk's procedure is the gold-standard technique in the treatment of thyroglossal cyst. Since it was first described in 2014, the modifications introduced by Koempel have allowed for a more reproducible suprahyoid approach. We present our initial experience with this technique. METHODS: A retrospective study of patients with thyroglossal cyst undergoing Koempel's technique in our institution from 2021 to 2022 was carried out. Demographic, clinical, and histological data was collected. RESULTS: In the study period, 5 patients -3 girls and 2 boys- underwent surgery. Median age and weight were 5 years (2-6) and 16 kg (14-25), respectively. All patients had suffered from previous infections, with 60% having cutaneous fistulization. In 2 patients, surgery was indicated following Sistrunk's procedure as a result of recurrence. Median operating time was 77 minutes (57-110), with the genioglossal muscle plane being identified in the 5 patients. No immediate complications were recorded, and diagnosis of thyroglossal cyst was histologically confirmed in all cases. One of the formerly recurrent patients had recurrence following surgery, but it was subclinical and incidentally diagnosed at control ultrasonography. The remaining patients had no recurrences after a median 8-month (1-12) follow-up period. CONCLUSIONS: Koempel's technique allows for a safe and reproducible approach of the suprahyoid segment. It is an attractive option in complicated cases as a result of previous infection or recurrence.
INTRODUCCION: La intervención de Sistrunk es el gold-standard en el tratamiento del quiste tirogloso pese a su imprecisión en cuanto a la disección suprahioidea. Tras su descripción en 2014, las modificaciones introducidas por Koempel, han permitido un abordaje suprahioideo más reproducible. Presentamos nuestra experiencia inicial con esta técnica. METODOS: Estudio retrospectivo de los pacientes con quiste tirogloso intervenidos mediante técnica de Koempel en nuestro centro en el periodo 2021-2022, recogiéndose datos demográficos, clínicos e histológicos. RESULTADOS: Durante el periodo de estudio se intervinieron 5 pacientes (3 mujeres/2 varones), con una mediana de edad y peso de 5 años (2-6) y 16 kg (14-25) respectivamente. Todos los casos habían sufrido infecciones previas presentando fistulización cutánea el 60%. En 2 de los pacientes se indicó la cirugía por recidiva tras intervención de Sistrunk. La mediana del tiempo quirúrgico fue de 77minutos (57-110) identificándose el plano del músculo geniogloso en los 5 pacientes. No hubo complicaciones inmediatas y el diagnóstico de quiste tirogloso se confirmó histológicamente en todos los casos. Uno de los pacientes del grupo con recidiva previa, presentó recidiva tras la intervención, siendo esta subclínica y diagnosticada incidentalmente tras ecografía de control. El resto de los pacientes no presentó ninguna recurrencia tras un seguimiento mediana de 8 meses (1-12). CONCLUSIONES: La técnica de Koempel permite un abordaje seguro y reproducible del segmento suprahioideo siendo una opción atractiva en casos complicados por infección o recidiva previa.

Thyroglossal cyst (TGC) is the most common congenital anomaly of the thyroid gland and is found in approximately 7% of general population. It represents cystic degeneration of a remnant of the thyroglossal duct that failed to involute during gestation. Malignancy occurring in TGC is rare entity, accounting only for 1% of all thyroglossal cysts. We are presenting such a rare case of papillary thyroid carcinoma arising in a thyroglossal cyst. 30-year-old female presented with a painless, gradually progressive swelling below the chin extending to left side. On examination, swelling was noted in submental region and measuring 4 × 3 × 1 cm, firm in consistency and moves with deglutition and movement of tongue. On radiological investigations, lobulated cystic lesion in midline with thin septations was seen, suggestive of thyroglossal cyst. The thyroid of the patient was normal. Patient underwent Sistrunk procedure. On histopathology, papillary thyroid carcinoma in thyroglossal cyst was seen and it was invading cyst wall and superficial skeletal muscle. The 1st case of thyroglossal duct carcinoma was reported by Brentano in 1911. Till now 300 cases have been reported in literature. Carcinomas occurring in thyroglossal cyst are extremely rare, (< 1% cases). The most frequent histological type is papillary pattern followed by mixed(papillary and follicular), squamous cell, Hürthle cell, follicular and anaplastic variety. The etiology of thyroglossal duct carcinoma is unknown and neither good clinical history nor examination can lead to a preoperative diagnosis. Diagnosis is often incidental on histopathology as in present case. Thyroglossal duct carcinoma is a rare condition that comes as a surprise to both the patient and surgeon and should be considered in patients presenting with cystic midline neck masses.
RESUMO
Thyroglossal duct cysts (TGDCs) are congenital and developmental abnormalities in infants and young children. This retrospective case series study examined the characteristics of 7 patients <3 years (mean age, 1.9 years) with TGDC complicated with a parapharyngeal mass treated at one hospital between January 2019 and 2022. Four patients had a painless mass around the neck, 2 had a painless mass associated with snoring, and 1 presented repeated swelling and pain. B-ultrasound suggested 6 cases of TGDC and 1 possible lymphangioma. All patients were treated with Sistrunk surgery to remove the TGDC. Six patients had no cyst recurrence during follow-up (6 months to 2 years). In conclusion, TGDC complicated with a parapharyngeal mass has complex and variable clinical manifestations. Completely removing the cyst while sparing thyroid cartilage and surrounding vascular and neuroanatomical structures is important to avoid complications. The patients are likely to be free from recurrence after surgery.

Introduction: Thyroglossal duct cyst (TGDC) is the most frequently encountered developmental anomaly in thyroid genesis with a reported incidence of 7% in the adult population. The cyst is known to develop anywhere along the pathway of thyroid descent but is more frequently seen in the infrahyoid neck in the midline. The incidence of malignancy in a TGDC is approximately 1%; a majority of these are papillary carcinomas. This study was conducted at a single tertiary care centre which spanned over a decade which adds practice changing evidence-based knowledge to existing literature on this rare entity. A comprehensive study which conclusively establishes the imaging features predictive of malignancy in TGDC carcinomas (TGDCa), the protocol for optimal management, clinical outcome and long-term survival of these patients is not available. Although TGDC carcinoma is thought to have an excellent prognosis, there is not enough data available on the long-term survival of these patients. The aim of this study was to identify whether neck ultrasound (US) can serve as an accurate imaging tool for the preoperative diagnosis of TGDC carcinomas. Methods: We accessed the electronic medical records of 86 patients with TGDC between January 2005 to December 2021. Of these, 22 patients were detected with TGDC papillary carcinoma on histopathologic examination. Relevant imaging, treatment and follow up information for all cases of TGDC carcinoma were retrospectively reviewed. We compared US characteristics predictive of malignancy across outcomes groups; malignant vs benign using the Chi-square test. Based on the results, a TGC-TIRADS classification was proposed with calculation of the percentage likelihood of malignancy for each category. Results: Compared to benign TGDCs, malignant TGDCs were more likely to present with following US characteristics: irregular or lobulated margins (90.40 vs. 38.10%), solid-cystic composition (61.90 vs. 17.07%), internal vascularity (47.62 vs. 4.88 %), internal calcification (76.19 vs. 7.32 %) (each p value < 0.005). Calcifications and internal vascularity were the most specific while irregular/lobulated margins were the most sensitive feature for malignancy. AUC under the ROC curve was 0.88. Allpatients were operated and were disease free at the end of 5 years or till the recent follow up. Discussion: US is the imaging modality of choice for pre-operative diagnosis of TGDC carcinoma. Thepre-operative diagnosis and risk stratification of thyroglossal lesions will be aided by the application of the proposed TGC-TIRADS classification, for which the percentage likelihood of malignancy correlated well with the results in our study. Sistrunk procedure is adequate for isolated TGDC carcinoma; suspicious neck nodes on imaging also necessitates selective nodal dissection. Papillary carcinomas have an excellent prognosis with low incidence of disease recurrence.
RESUMO
INTRODUCTION: Thyroglossal duct cysts (TGDC) are the commonest midline developmental cyst and have a bimodal age distribution. They usually develop in an infrahyoid position. A National survey of TGDC practice among otolaryngologists in 2012 recommended preoperative investigation with ultrasound, with or without blood tests. METHODS: Retrospective analysis of preoperative investigation for clinically diagnosed TGDC surgeries between 2012 and 2020 in a single tertiary centre was undertaken. This was collated alongside postoperative outcomes (histology, recurrence, hypothyroidism). Comparison was made with the 2012 national survey. RESULTS: Ninety-five cases of thyroglossal duct surgery in children and adults were studied. Demographic data were comparable to the literature. Ultrasonography was the most commonly used preoperative investigation. Histology of 71% of excised cysts confirmed TGDC with another 8% reported as development cysts. The excision of the cyst with a cuff of strap muscles and middle portion of hyoid bone had the lowest recurrence rate, which was 4% overall in this study. There were no cases of ectopic thyroid tissue or postoperative hypothyroidism. DISCUSSION AND CONCLUSION: Nearly a decade of thyroglossal duct cyst excisions in a large-volume unit gave detail on actual preoperative practice and outcomes. Practice was found to be consistent overall with the 2012 recommendations although not standardised across all cases. From this experience, and a literature review, a visual guide on preoperative investigations for different age groups in the form of a flow chart is proposed to reduce risk of complications while avoiding unnecessary investigations.

Background Thyroglossal tract anomalies are the most common cause of midline neck swelling. Thyroglossal cysts present between the base of the tongue and cricoid cartilage as painless, midline swelling that moves on deglutition and protrusion of the tongue. If the thyroglossal cyst gets infected or is violated surgically, it can result in a thyroglossal sinus or fistula. Investigations in patients with suspected thyroglossal cysts include a thyroid function test, ultrasonography of the neck, and fine needle aspiration cytology (FNAC). Computed tomography (CT) or magnetic resonance imaging (MRI) can be done for larger cysts or suspected malignancies. The gold standard treatment is Sistrunk surgery. Recurrence rates with Sistrunk surgery are lower when the surgery is performed accurately. This study was conducted to document the clinical presentation and treatment outcome in patients treated for thyroglossal tract anomalies. Methods This is a retrospective analysis of 46 medical case records of patients operated on for thyroglossal tract anomalies at a rural tertiary care hospital from April 1995 to April 2021. Patients fulfilling the inclusion and exclusion criteria were evaluated with a detailed history, various clinical presentations, location, extent of anomalies, and thyroid function test results documented. Ultrasound images were reviewed, and the findings were documented. All patients have consent, and they underwent Sistrunk surgery. Patients in whom the normal thyroid gland was found to be absent were started on replacement thyroxine after surgery. The specimen was subjected to histopathological examination by a senior pathologist. The outcome regarding complications, recurrence, and further treatment were reviewed. The outcome of the thyroglossal fistula was compared with that of thyroglossal cysts, and the outcome of infrahyoid thyroglossal tract anomalies was compared with that of suprahyoid thyroglossal tract anomalies. Results In this study, among the 46 patients, 24 (52.2%) were female and 22 (47.8%) were male. The minimum age was three years, the maximum was 58, and the mean was 20.6 years. In this study, 71.7% of the patients were diagnosed with thyroglossal cysts, 10.9% had thyroglossal fistulas, and two had lingual thyroids. The most common location of the cyst was infrahyoid (73.9%). 44 patients underwent Sistrunk surgery, and two patients diagnosed with lingual thyroid underwent excision. Three patients had complications (two pharyngo-cutaneous fistulas, one wound dehiscence), and all were managed conservatively. There were no recurrences in our study. Conclusion Thyroglossal tract anomalies are the most common congenital cervical anomalies. A complete Sistrunk procedure includes the removal of the entire thyroglossal tract, inclusive of the body of the hyoid bone along with the cuff of base tongue tissue, and gives the best result for thyroglossal tract anomalies.
RESUMO
Papillary carcinoma constitutes 80% of thyroglossal duct cyst carcinoma (TGCC). The mainstay of treatment for TGCC is Sistrunk procedure. Due to lack of clear-cut guidelines in managing TGCC, the role of total thyroidectomy, neck dissection and adjuvant radioiodine therapy is still debatable. This was a retrospective study which included cases of TGCC treated in our institution over a period of 11 years. The aim of study was to assess the need for total thyroidectomy in management of TGCC. Patients were divided into two groups based on the surgical treatment they underwent and the treatment outcomes were compared. The histology was papillary carcinoma in all cases of TGCC. Overall, 43.3% of TGCCs had a focus of papillary carcinoma in total thyroidectomy specimen. Lymph node metastasis was noted only in 10% of TGCC and not identified in isolated papillary carcinoma confined to thyroglossal cyst. 7-year overall survival (OS) for TGCC was 83.1%. Prognostic factors like extracapsular extension or lymph node metastasis did not affect OS. Addition of total thyroidectomy and neck dissection to Sistrunk procedure did not offer any survival advantage. In a case of TGCC, FNAC should be done from any clinically suspicious thyroid nodules or lymph nodes. TGCC has a good prognosis following treatment and none of the cases in our series has disease recurrence during follow-up. Sistrunk procedure was an adequate procedure for treatment of TGCC with clinically and radiologically normal thyroid gland.
RESUMO
Thyroglossal duct cyst (TGDC) rarely becomes symptomatic in the neonatal period unlike other congenital neck swellings which present with high airway obstruction. An infrahyoid TGDC presenting with airway compromise in a neonate is even rarer. We hereby report a newborn with significant respiratory distress necessitating intubation and ventilation since birth. He had multiple extubation failures and signs of upper airway obstruction post-extubation. Computed tomography demonstrated a cystic lesion, probably an infrahyoid TGDC compressing the laryngeal lumen. The cyst was removed by Sistrunk procedure and histopathology confirmed the diagnosis. The child was discharged 5 days after surgery and was asymptomatic on follow-ups.
RESUMO
Aims and Objectives: Thyroglossal duct cyst (TDC) is a common congenital cyst with an incidence of about 7%. Thyroglossal duct cyst carcinoma (TDCC) is a rare sequel which arises from TDC and has an incidence of about 1%. As these are rare, they do not have well-defined management guidelines. The aim of this study was to analyse the clinical profile and pathological characteristics of patients with thyroglossal duct cyst carcinoma and to propose a protocol for their treatment and follow-up. Materials and Methods: A retrospective study was done from January 2000 to December 2019. All the clinical details, imaging characteristics, treatment and histopathology were analysed. Results: The mean age group in our study was 37.9 years with a female preponderance. The clinical features like rapid increase in size, fixity of the lump and lymph node metastasis were not very common. Seventy-five percent of our patients who underwent imaging had suspicious characteristics. Fifty-six percent of our patients had FNAC suggestive of TDCC. Fifty percent of our patients had concomitant thyroid carcinoma. None of our patients had distant metastasis at follow-up. Conclusions: TDCC is rare and a disease of young adulthood and usually has good prognosis. It may be a clinical surprise or a small lesion which can be detected with ultrasound and targeted FNAC. There is high rate of concomitant thyroid carcinoma and hence needs careful assessment. Sistrunk's procedure with total thyroidectomy either staged or simultaneously has good outcome and permits adjuvant treatment.
RESUMO
OBJECTIVE: The incidence of thyroglossal duct diseases in the general population is about 7%. We aimed to demonstrate the clinical presentations and management of thyroglossal duct diseases. METHODS: We conducted a retrospective review of all patients who underwent surgery for histopathologically confirmed thyroglossal duct cyst, sinus, or fistula at a single center. RESULTS: A total of 151 cases were included in this study. There were more female patients (87, 58%) than male patients (64, 42%). The patients' ages ranged from 1 to 63 years old. The most prevalent complaint was painless upper midline neck swelling (93.3%). Most cases were diagnosed as thyroglossal duct cysts (137, 90.7%). Six cases (4%) were associated with carcinoma. All the cases were managed using the modified Sistrunk procedure. There were no procedure-related complications, and five cases of recurrence. CONCLUSIONS: Although thyroglossal duct cyst is the most common neck anomaly in children, it may also present with various characteristics later in life. This condition can be managed successfully without complications and with a low recurrence rate.

OBJECTIVE: To review the clinical presentation, diagnosis, pathology and management strategies in a modern cohort of patients with thyroglossal duct cyst carcinoma. STUDY DESIGN: Retrospective case series following PROCESS Guidelines. SETTING: Comprehensive cancer centre. METHODS: Data recorded included: gender, age at diagnosis, clinical presentation, thyroid function, diagnostic investigations, cytological results, final histology, staging and follow up status. The risk of malignancy in cytological analysis was stratified according to the Royal College of Pathologists classification in United Kingdom. RESULTS: Twelve patients were included. The majority of patients (66.7%) presented with an isolated thyroglossal duct cyst. Only 4 patients had preoperative cytological suspicion of carcinoma (sensitivity: 33.3%). At the time of presentation all patients were euthyroid. Following diagnosis of malignancy, a total thyroidectomy was performed in all patients, with the exception of 2, who had a thyroglossal duct cyst carcinoma of less than 10mm. Among the 10 patients who underwent total thyroidectomy, 7 (70%) patients had proven carcinoma in the thyroid gland, 3 with deposits of less than 10mm. The average size of the thyroid cancer deposits was 7.2mm (1-20mm). With a mean follow-up of is 44 months (5-120), all patients were alive and free of recurrence at the end of the study period. CONCLUSION: Thyroglossal duct cyst carcinoma is a rare condition and its management should be discussed in a multidisciplinary meeting. As with differentiated thyroid cancer originating in the thyroid gland, it bears extraordinary survival rates. Accordingly, the management of these cancers has shifted towards a more conservative approach although its peculiarities must be taken into account: ease of extracystic invasion and possible different lymph node invasion.

Ectopic thyroid tissue can be present in the embryonal path of descent of the thyroglossal duct anywhere from the foramen caecum to the thyroid gland. However, for such ectopic thyroid tissue to be hyperfunctioning is quite rare. Here, we discuss a 56-year-old female patient who presented with persistent thyrotoxicosis for over 7 years. She had undergone thyroidectomy in 1982 for thyrotoxicosis and was rendered hypothyroid (thyroid-stimulating hormone of 75 µIU/mL). Whole-body technetium scan was done twice which did not show any uptake in the neck or other parts of the body and an empirical dose of 15 mCi of radioiodine therapy was also given to treat the thyrotoxicosis. She continued to be thyrotoxic and was on carbimazole 30 mg/day along with beta-blockers. In 2021, an Iodine131 whole-body scan revealed small remnant thyroid tissue and an ectopic thyroid tissue in a thyroglossal cyst. In such cases of persistent or recurrent thyrotoxicosis despite standard treatments, an ectopic location should be sought after and treated.
