Cáncer Papilar en Quiste Tirogloso. Caso Clínico y Revisión de la literatura / Papillary Cancer in Tirogloso Cyst. Case report and review of literature

INTRODUCCIÓN: Los quistes tiroglosos son las lesiones más comunes de la línea media cervical y se ha descrito el carcinoma papilar de tiroides en el 1%. Debido a su baja incidencia no existe un consenso acerca del tratamiento óptimo. Caso clínico: Paciente mujer de 34 años de edad consulta por aumento de volumen cervical doloroso y se evidencia nódulo doloroso en región cervical media. Ecografía de tiroides visualiza una lesión quística compleja. Se completa el estudio con tomografía computada del cuello con contraste que evidencia quiste del conducto tirogloso con compromiso inflamatorio-infeccioso, por lo que se decide cirugía. Biopsia evidencia cáncer papilar de 0.25 cm en quiste del conducto tirogloso, con bordes quirúrgicos negativos. Por bajo riesgo se decide control imagenológico estricto. DISCUSIÓN: Los quistes del conducto tirogloso comprenden las lesiones cervicales congénitas más frecuentes. Se presentan como masas indolentes y asintomáticas. El diagnóstico es confirmado mediante ecografía y la tomografía es utilizada para ampliar el estudio. La aparición de cáncer tiroideo en estos quistes es poco común, y generalmente son indistinguibles de las lesiones benignas en el preoperatorio. En relación al manejo del cáncer papilar en quiste del conducto tirogloso no existe un consenso de su tratamiento óptimo. Para los casos de bajo riesgo se sugiere control anual con TSH y ecografía tiroidea. Para aquellos pacientes de alto riesgo se sugiere tiroidectomía total y ablación de los restos tiroides con yodo radioactivo, con control anual con niveles de tiroglobulina. El pronóstico es excelente, con tasas de remisión que superan el 95%. CONCLUSIONES: Los carcinomas en quistes de conducto tirogloso son poco comunes y en la mayoría de los casos son lesiones diagnosticadas de manera incidental después de la resección quirúrgica. Para definir necesidad de tiroidectomía, debe realizarse estudio individualizado por un equipo multidisciplinario con amplia experiencia.

INTRODUCTION: Thyroglossal cysts are the most common affection of the cervical midline. Papillary carcinoma has been described in 1% of this cysts. Due to its low incidence a consensus on the optimal treatment does not exist. Clinical case: A 34 year old female with no relevant past medical history, presented with a painful cervical mass of many weeks of appearance. The thyroid ecography showed a complex cystic lesion and the cervical computed tomography with contrast evidenced a cyst of the thyroglossal duct with inflammatory and infectious findings. Surgery with no incidents was performed. Biopsy reported a 0.25 cm papillary cancer in the thyroglossal duct cyst, with negativa surgical margins. Strict follow up with imaging studies was decided. DISCUSSION: the thyroglossal duct cyst are the most common congenital cervical affections. Classically, they present as indolente, asyntomatic masses on the cervical midline. The diagnosis is confirmed with ecography and computed tomography is used to extent evaluation. Thyroid cancer in thyroglossal duct cyst is uncommon and generally indistinguishable from benign lesions in the preoperative phase. A consensus regarding the optimal management of this patients does not exist. For low risk cases, an anual control with THS and thyroid ecography is suggested. For patients with high risk a Sistrunk with total thyroidectomy and radioactive ablation of thyroids remnants is recommend. Follow up with anual thyroglubin levels should be performed. The prognostic is excellent, with more than 95% remission rates. CONCLUSSIONS: Thyroglossal duct cyst carcinomas are rare. In most cases, diagnosis is made incidentally after surgical resection. To decide wheter thyroidectomy is necessary each case should be analyzed individually by a multidisciplinary team with vast experience.

Papillary Thyroid Carcinoma within Thyroglossal Duct Cyst: Case Series and Literature Review

Abstract Introduction Thyroglossal duct cyst (TGDC) is themost common congenital anomaly of the neck, and approximately 7% of all the adult population presents it. Ectopic thyroid tissue is found in the thyroglossal duct cyst wall in up to 65% of cases. This thyroid tissue has the potential to develop some type ofmalignancy, themost common of which is the papillary carcinoma of the thyroid. There are just over 270 cases of thyroglossal duct cyst malignancy reported in the literature. Objectives We aimed to study our population of patients in order to identify cases with thyroglossal duct cyst malignancy. Methods A retrospective chart review was conducted in the section of otolaryngology/ head and neck surgery at a hospital in Karachi, Pakistan, from January of 2004 to December of 2014 on patients with the diagnosis of thyroglossal duct cyst. Results Fifty-eight patients were diagnosed with TGDC, two of whom also presented with thyroglossal duct cyst carcinoma. Both patients revealed papillary thyroid carcinoma on histopathology. Case 1 had an open biopsy before undergoing definitive surgery. Both patients underwent subsequent total thyroidectomy after Sistrunk procedure, and case 2 had selective neck dissection revealing lymph node metastasis. Conclusion Thyroglossal duct cyst carcinoma is a rare finding that comes as a surprise to both the patient and the surgeon. We report 2 out of 58 cases diagnosed with thyroglossal duct cyst carcinoma.

Carcinoma papilar de tiroides en quiste del conducto tirogloso / Thyroglossal duct cyst with papillary carcinoma

Introduction: In about 1-2 percent of cases of thyroglossal cyst may be neoplastic changes, mostly correspond to papillary thyroid carcinoma (75-85 percent). The aim of this paper is to present 9 cases of papillary thyroid carcinoma in thyroglossal duct cyst. Materials and Methods: Data were recorded retrospectively from patients diagnosed with papillary thyroid carcinoma in thyroglossal duct cyst treated at Hospital Clínico Universidad de Chile between 1999 2014. Results: From 142 cases operated for thyroglossal duct cyst, 9 cases of papillary cancer (6.34 percent) were recorded. The average age was 32 years. The average diameter of the lesion was 4.4 cm (SD 2.2 cm). 8 patients underwent total thyroidectomy; a simultaneous thyroid cancer was diagnosed in 3 of them. In 6 cases was added iodine therapy. In only one patient a lymph nodal dissection was performed. We do not observe any surgical complication. A solid component in preoperative ultrasonographic study is suspicious of malignancy. The average follow-up time was 85 months. There is no recurrence or mortality in this group of patients. Conclusions: Although the safest long term management is Sistrunk surgery associated with thyroidectomy and radioiodine in selected cases, these patients must be evaluated by a multidisciplinary group and thyroidectomy should be considered in high surgical volume center, in order to minimize complications.

Introducción: En alrededor de 1-2 por ciento de los casos de quiste tirogloso pueden existir cambios neoplásicos, en su mayoría corresponden a carcinoma papilar de tiroides (75-85 por ciento). El objetivo de este trabajo es presentar 9 casos de carcinoma papilar de tiroides en quiste del conducto tirogloso, en cuanto a su forma de presentación y manejo. Material y Método: Se registraron en forma retrospectiva datos de pacientes condiagnóstico de carcinoma papilar de tiroides en quiste del conducto tirogloso atendidos en el Hospital Clínico de la Universidad de Chile entre 1999 2014. Resultados: De 142 casos de pacientes operados por quiste del conducto tirogloso, se registraron 9 casos de cáncer papilar (6,34 por ciento). El promedio de edad de los pacientes fue de 32 años. El diámetro promedio de la lesión fue de 4,4 cm (DS 2,2 cm). Del total, 8 pacientes fueron sometidos a tiroidectomía total, se diagnosticó cáncer de tiroides en 3 de ellos, en 6 se asoció tratamiento con radioyodo. En sólo 1 paciente se realizó una disección linfonodal. El tiempo promedio de seguimiento fue de 85 meses; a la fecha la serie no ha presentado recurrencia ni mortalidad. Conclusiones: Si bien el manejo más seguro a largo plazo es la cirugía de Sistrunk, asociado a una tiroidectomía y eventual radioyodo, la resolución quirúrgica con tiroidectomía asociada debe ser considerada cuando la morbilidad no sea mayor que el beneficio teórico.

Thyroglossal sinus; demographic and anatomical features of thyroglossal sinus

To assess demographic and anatomical features of thyroglossal sinus. Descriptive. ENT department Allied Hospital Faisalabad. From Jan 2005 to June 2010. The patients were admitted through ENT out patient department. The data was collected on the basis of history, physical examination, investigations, management and follow up. Total 60 patients 35 males [58%] and 25 females [42%]. The majority of patients were from second decade of life 28 [47%]. The most common location of thyroglossal sinus was thyrohyoid 55 [92%]. The etiology of of thyroglossal sinus in majority of cases was iatrogenic 50 [83%]. The common clinical presentation was discharging sinus in the neck 60 [100%]. The histological diagnosis in all the cases was benign 60 [100%].All the patients were managed by Sistrunks operation 60 [100%].The recurrence was seen in 4 cases [07%]. The incidence of thyroid carcinoma was 00%. Overall success rate was 93%. The prevalence of thyroglossal sinus is quite considerable. The majority of cases are iatrogenic which means that more awareness is required about diagnosis and proper management of thyroglossal cyst. The incision and drainage of thyroglossal cyst should be avoided to prevent the development of thyroglossal sinus. In all the cases the specimen should be sent for histopathology to rule out the thyroid carcinoma

Carcinoma en quiste tirogloso / Carcinoma in thyroglosal duct cyst

El carcinoma diferenciado de tiroides en quiste tirogloso (CaQT) es una rara entidad. En diferentes series de pacientes operados por quistes tiroglosos su incidencia fue del 0.7 al 1.07%. Luego de la extirpación del quiste por el procedimiento de Sistrunk, no hay consenso sobre la indicación de tiroidectomía total, radioablación y/o terapéutica supresiva con levotiroxina. El objetivo del Departamento de tiroides de SAEM, fue evaluar: formas de presentación, evolución clínica, métodos diagnósticos de utilidad y tratamiento para consensuar futuras conductas. Material y Métodos: Estudio multicéntrico, retrospectivo en 22 pacientes entre 10 a 69 años, 15 mujeres y 7 varones. Resultados: El tamaño de los quistes osciló entre 1 y 8 cm (Mediana= 3.0 cm, Χ ± DS= 3.7 ± 2.2 cm). La mitad de los pacientes presentó crecimiento del quiste en los 6 meses previos a la cirugía. La punción resultó sospechosa en 2/5 quistes y positiva en uno. La ecografía tiroidea evidenció nódulos en 4/13 casos (30%). Se realizó tiroidectomía en 17/22 pacientes (total: 15 y subtotal: 2). La histología del CaQT demostró carcinoma papilar en 21 y carcinoma folicular en uno. Hubo coexistencia de cáncer intratiroideo en el 23.5% de los casos, ninguno multicéntrico. Dos pacientes presentaron metástasis ganglionares y otro tuvo compromiso muscular (ninguno de ellos coexistió con cáncer intratiroideo). Se radioablacionó a 13 pacientes. En 9/11 pacientes la tiroglobulina permaneció indetectable durante el seguimiento (1 a 14 años). Conclusiones: 1) Realizar ecografía de cuello y punción ecoguiada a todo paciente con quiste tirogloso. 2) En caso de CaQT combinar simultáneamente tiroidectomía total y procedimiento de Sistrunk. 3) Evaluar radioablación complementaria y tratamiento supresivo con levotiroxina en cada caso. 4) Efectuar el seguimiento tal como en los carcinomas ortotópicos.

Differentiated thyroid carcinoma (DTC) in thyroglosal duct cyst (TGDC) is rare, ranging from 0.7 to 1.07% in different series. After the surgery of choice (Sistrunk procedure) the other alternative treatments such as thyroidectomy (Tx), radioiodine and L-T4 therapy are controversial. OBJECTIVE: to evaluate several and controversial aspects in the largest series of DTC in TGDC reported in the literature. Subjects and methods: retrospective multicentric study: n= 22, aged 10-69 yrs. (15 females and 7 men) who underwent the Sistrunk procedure for TGDC. Results: none of the TGDC was less than 1 cm (median 3.0 cm, Χ±SD= 3.7 ± 2.2cm). In half of them there was an increased cystic size in the last 6 months before surgery. Cyst FNA was suspicious in 2/5 and positive in one, whereas the histological diagnosis of the operated TGCD was papillary cancer in 21 and 1 follicular carcinoma. Thyroid ultrasound (US) (n=13) showed nodules in 30% of the cases. Tx was performed in 17/22 (total: 15, subtotal: 2). Thyroid DTC coexisted in 4/17 (23.5%), and was unilateral in all of them. Lymph node metastases were present in 2 adults and muscle involvement was found in the 10-year old girl. None of these 3 patients had overt thyroid lesions. 131-I therapy was performed in 10 patients. In 9 out of 11 subjects Tg remained undetectable during follow-up (1-14yrs.). Persistent high Tg was present in one case without thyroid DTC. Conclusions: 1) Ultrasonography and FNAB should be performed to every patient with thyroglossal duct cyst 2) In case of TGDC, total Tx and Sistrunk's procedure should be simultaneously combined 3) 131-I therapy and L-T4 suppressive treatment should be evaluated in every case 4) Follow-up as in the DTC.

Thyroglossal Duct Cyst Imaging: Thyroid Scintigraphy Versus Ultrasound

The two imaging modalities most frequently used in thyroglossal duct cyst (TDC) are thyroid scintigraphy and ultrasound. The imaging is mainly used to exclude the cyst from being the only functioning ectopic thyroid tissue. The main objective of this study is to compare the results of scintigraphy and ultrasound. Methods: A total of 56 patients referred to the National Cancer Institute (NCI); University of Gezira in the period from Jan 2007 to Dec 2009 were included in this study; 30 females and 26 males patients; with median of 12.5 years. Data were analyzed by SPSS software. Results: Both thyroid scintigraphy and ultrasound reached the same imaging findings i.e. 53 patients with TDC and 3 patients with ectopic thyroid tissues. The Fisher exact test revealed no significant difference between the two modalities final results (P- value = 1). In addition; Pearson correlation showed complete correlation between the final ultrasound and scintigraphy results (R2 = 1; P-value 0.0001). Furthermore; ultrasound has provided detailed cyst characterization. Conclusion: Both modalities revealed almost identical results. Ultrasound has the additional advantages of being non-ionizing radiation and accurately localizes and characterizes the TDC

Papillary carcinoma of thyroglossal duct cyst

Carcinoma arising from thyroglossal duct cyst [TGDC] is rare and account for 1 - 2% of all excised cysts. It is debatable the origin of these tumours whether primarily arising from the TGDC or from metastasis from the thyroid gland. Papillary carcinoma is the most common encountered histological type but the diagnosis usually obtained postoperatively. The aim of this study is to highlight this rare condition and to discuss the origin of these tumours. The preoperative diagnostic technique, histological criteria for diagnosis and treatment modalities were highlighted. Retrospective study. Pathology Departments, Military Hospital and Salmaniya Medical Complex, Bahrain. Patients with TGDC papillary carcinoma who have been diagnosed postoperatively on histological examination after simple Sistrunk's operation during the study period from January 2002 to December 2008 were followed up for six and two years respectively. Patients' characteristics, clinical presentations and outcomes were reviewed. Two patients were encountered during the study period. Both presented with classical features of congenital midline thyroglossal duct cyst. The first patient had a localised tumour and was free of tumour recurrence for 6 years postoperatively. The second patient's tumor spread to surrounding tissue and lymph nodes, which necessitated aggressive surgery. Papillary Carcinoma of the TGDC is a rare entity, it is usually a localised disease which has excellent prognosis after simple surgery in most cases We present two cases of carcinoma of TGDC diagnosed postoperatively after simple Sistrunk's operation; one case had no recurrence and the other had widespread dissemination, which necessitated aggressive surgery. The histological diagnostic criteria of these tumours, their origin from the duct or the main gland were reviewed with treatment modalities

Rare site of papillary carcinoma

Papillary carcinoma of the thyroglossal cyst is a rare disease found in a 21 year-old female patient. Histopathological examination of a completely excised thyroglossal cyst established the diagnosis. Clinically, no differentiation between a benign cyst and malignancy could be made. Neck ultrasonography demonstrates a solid-cystic mass at the midline of the neck and may give the possibility of malignant changes in a thyroglossal cyst and may help in the preoperative diagnosis. Complete excision of the cyst with its tract and a central portion of the hyoid bone is usually sufficient. Long term follow up of the patient is recommended

[Congenital cysts and branchial fistula of the head and neck: a 148 cases report]

We report our experience of 148 cases of congenital cystic anomalies of the head and neck, operated in a twenty-year period. The goal of this study is to evaluate the frequency of the different anomalies and our diagnostic and therapeutic approach. This retrospective study has analyzed 148 cases of children who had surgery for a congenital cyst or fistula of the head or the neck. Thyroglossal duct cyst was the most frequent anomaly [52.7%]. The diagnosis was mostly clinical without need to further explorations. Surgical repair was well codified and consisted in an excision of 78 thyroglossal cysts, 41 dermoid cysts and 29 branchial fistulas. Six cases of thyroglossal cysts needed redo surgery. Six other patients had non specific complications

Review of congenital neck masses in assir central hospital of Saudi Arabia

The aim of retrospective study of 60 patients with congenital neck masses seen in our tertiary institution from 1991-1998 is to highlight their pattern in our local setting and to compare our clinical diagnosis with the results of conventional investigations of fine needle aspiration cytology, ultrasound findings and computerized axial tomographic [CT] Scan.We reviewed all cases of congenital neck masses referred and found in the medical records of this main referral hospital in the Assir region of the Kingdom of Saudi Arabia between January 1991 and December 1998. Ultrasound and CT scan confirmed clinical diagnosis in 90% of cases while only 50% were confirmed by fine needle aspiration cytology. Thyroglossal duct cysts were the most common, accounting for 60% of our cases. The mean age at presentation varied from cyst to cyst.Total surgical excision was the treatment of choice in throglossal duct cysts and branchial cycts. The decision to treat or operate in lymphangioma and haemangioma remains that of the surgeon, especially where there are no obstructive symptoms. Ultrasonography and CT scan are in valuable in the differential diagnosis and management of congenital neck masses

Primary papillary carcinoma in a thyroglossal cyst.

Papillary carcinoma arising in a thyroglossal cyst is rare. There is controversy regarding optimum management. We report a case managed by Sistrunk's procedure and external radiotherapy and review the literature on the subject.

Radiologic-Pathologic Correlation of Unusual Lingual Masses:Part I: Congenital Lesions

Because the tongue is superficially located and the intial manifestation of most diseases occurring there is mucosal change, lingual these lesions can be easily accessed and diagnosed without imaging analysis. Most congenital lesions of the tongue, however, can manifest as a submucosal bulge and be located in a deep portion of that organ such as its base; their true characteristics and extent may be recognized only on cross-sectional images such as those obtained by CT or MRI. In addition, because it is usually difficult to differentiate congenital lesions from other submucosal neoplasms on the basis of imaging findings alone, clinical history and physical examination should always be taken into consideration when interpretating CT and MR images of the tongue. Although the radiologic findings for congenital lesions are nonspecific, CT and MR imaging can play an important role in the diagnostic work-up of these unusual lesions. Delineation of the extent of the tumor, and recognition and understanding of the spectrum of imaging and the pathologic features of these lesions, often help narrow the differential diagnosis.
