Papillary carcinoma in a thyroglossal duct remnant: a case report / 临床耳鼻咽喉头颈外科杂志

This case report has described a case of papillary carcinoma of thyroglossal duct in a young male. This patient was admitted with a mass in the anterior neck for 2 years. Preoperative Bultrasonography, CT and MR showed a subcutaneous cystic mass with irregular calcification shadow in the central region of the neck without obvious enhancement. Initial diagnosis was thyroglossal duct cyst, and was excised by Sistrunk under general anesthesia. The postoperative pathological examination showed thyroglossal duct cyst combined with thyroid papillary carcinoma, which was confirmed by immunohistochemistry as thyroglossal duct papillary carcinoma.

Transoral robotic surgery for treatment of lingual thyroglossal duct cyst / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the feasibility, safety and efficacy of transoral robotic surgery (TORS) in the treatment of lingual thyroglossal duct cyst (LTGDC). Methods: The clinical data of 10 patients with LTGDC treated with TORS in Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from May 2017 to November 2020 were analyzed retrospectively,including 6 males and 4 females, aged 5-44 years. The cysts were fully exposed, and resection usually started from the cephalic side of lesions. The range of resection was 3 to 5 mm away from the lesions, and partial hyoid bone was removed if necessary. Intra-operative robotic set-up time,operation time and estimated blood loss,and post-operative local bleeding, dyspnea and recovery time for oral intake were analyzed. SPSS 12.0 software was used for statistical analysis. Results: The cysts in all 10 patients were successfully resected by TORS with da Vinci Si surgical system. The mean robotic set-up and exposure time, operation time, estimated intraoperative blood loss and recovery time for oral intake were (15.5±7.1) min, (17.6±7.4) min, (8.9±6.4)ml and (2.3±2.2)days, respectively. No patient required tracheostomy intra-or post-operatively, and no symptoms of airway obstruction, postoperative bleeding, pharyngeal fistula, hoarseness and neurological impairment occurred after operation. The patients were followed up for 5 to 47 months, with median follow-up time of 17 months, and no recurrence was observed. Conclusion: TORS is safe and feasible for resection of LTGDC, with rapid recovery and low recurrence rate.

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.

Experiencia en el manejo de la patología del conducto tirogloso: serie de casos / Experience in thyroglossal duct pathology: clinical case series

La patología del conducto tirogloso constituye la segunda anomalía cervical benigna más frecuente en la infancia. El diagnóstico es principalmente clínico. Sistrunk fue quien describió la técnica quirúrgica considerada de elección para el tratamiento definitivo de esta patología. Estudio descriptivo retrospectivo. Entre junio de 2008 y agosto de 2015 se realizaron 54 procedimientos en 45 pacientes (39 casos primarios). La mediana de edad fue de 4,7 años; 14/39 pacientes (31,1%) presentaron infección preoperatoria. Todos los pacientes fueron evaluados inicialmente por ecografía. Todos fueron tratados mediante la técnica de Sistrunk. La recidiva global fue de 17,8%.

The thyroglossal duct cyst pathology represents the second cause of bening cervical anomalies in childhood. Diagnosis is mainly clinical. Sistrunk (1920) proposed a surgical technique that is still considered the gold standard for definitive treatment of this condition. A retrospective study was made including patients who underwent surgery for thyroglossal duct cyst pathology in our department between June 2008 and August 2015. In this period, we performed 54 procedures in 45 patients (39 primary cases). Median age was 4.7 years; 14/39 patients (31.1%) had pre-operative infection. All patients were studied with neck ultrasound. A Sistrunk's procedure was performed in all cases. The global recurrence rate was 17.8% (8/45).

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.

Carcinoma papilar de quiste de conducto tirogloso sincrónico con carcinoma papilar de tiroides / Synchronous papillary carcinoma of thyroglossal duct cyst and papillary thyroid carcinoma

Presentamos el caso de un paciente diagnosticado de quiste de conducto tirogloso y un nódulo tiroideo ístmico en el que se evidenciaron focos de carcinoma papilar intraquístico concomitantes con carcinoma papilar en el nódulo tiroideo. La indicación terapéutica en estos casos es controvertida, y dependerá en la mayoría de los casos del estudio microscópico de la muestra. En nuestro caso se realizó en un primer tiempo la intervención de Sistrunk asociada a una istmectomía y tras conocer el resultado de ambas muestras se decidió realizar tiroidectomía total.

We report the case of a patient with a thyroglossal duct cyst and a nodule at the thyroid isthmus which showed intracystic papillary carcinoma foci concomitant with papillary carcinoma in the thyroid nodule. The therapeutic indication in these cases is controversial. In our case it was done in a first intervention a Sistrunk technique associated to an isthmectomy and after knowing the results of both samples was decided to perform a total thyroidectomy.

Carcinoma papilar de tiroides en quiste tirogloso / Papillary carcinoma in thyroglossal duct cyst

Background: to report a rare case of papillary carcinoma in thyroglossal duct cyst and discuss its management. Material and Method: a 72 year-old man was clinically diagnosed to have a big thyroglossal duct cyst. Sistrunk's procedure followed by total thyroidectomy on the evidence of papillary cancer in thyroglossal duct cyst. Results: histopathologic examination revealed a papillary carcinoma in the thyroglossal duct cyst and normallity in the thyroid gland. The patient remained free of disease on follow-up. Conclusion: most cancers arising in thyroglossal duct cyst are of low risk, and Sistrunk's procedure with a total thyroidectomy is an adequate treatment for such cancers.

Objetivo: reportar un caso raro de carcinoma papilar en un quiste tirogloso y discutir su manejo. Paciente y Método: un hombre de 72 años a quien se realizó un diagnóstico clínico de un quiste tirogloso, fue llevado a una cirugía de Sistrunk's y luego una tiroidectomía total ante la evidencia de cáncer papilar en el quiste tirogloso. Resultados: el examen histopatológico reveló un carcinoma papilar de tiroides en el quiste tirogloso y la glándula tiroides fue normal, el paciente permaneció libre de enfermedad en su seguimiento. Conclusiones: la mayoría de los cánceres que surgen en quiste del conducto tirogloso son de bajo riesgo, y el procedimiento Sistrunk's con una tiroidectomía total es un tratamiento adecuado para este tipo de cáncer.

Carcinoma papilar en quiste tirogloso: reporte de 4 casos y revisión de la literatura / Papillary carcinoma in a thyroglossal duct cyst: report of 4 cases and review of literature

Introducción: El quiste tirogloso es una de las masas cervicales más frecuentes. En 1 por ciento puede desarrollar un cáncer, siendo el más frecuente el carcinoma papilar tiroideo. Objetivo: Describir la presentación clínica, el diagnóstico, el manejo y la evolución de los casos de carcinoma papilar tiroideo en quiste tirogloso. Material y método: Se revisaron los archivos del Departamento de Patología de la Universidad de Concepción desde 2000 a 2010 analizando las fichas clínicas y el informe de la biopsia.

Dos casos fueron sometidos a tiroidectomía total y terapia con radioyodo complementaria. Sólo un paciente presentaba un cáncer sincrónico en la tiroides. El seguimiento promedio fue de 4,7 años y no se presentaron recidivas. Conclusiones: Se encontraron 4 casos, se analiza su presentación, diagnóstico, tratamiento y evolución.

Introduction: Thyroglossal duct cyst is one the most frequent cervical masses. Cancer may develop from 1 percent among them, thyroid papillary carcinoma being the most frequent. Aim: To describe the clinical presentation, diagnosis, management and evolution of thyroid papillary carcinoma cases in thyroglossal duct cyst. Material and method: A review was made of the files from the department of pathology of the Universidad de Concepción, since 2000 to 2010, analyzing clinical records and biopsy reports. Results: Four cases of papillary carcinoma in a thyroglossal duct cyst were found, all female with a mean of age of 42 years. All of them underwent Sistrunk procedure. Two cases underwent total thyroidectomy and complementary radioiodine therapy. Only one patient presented synchronic thyroideal cancer. The mean time of follow up consisted of 4,7 years, with no reported recurrence. Conclusions: We found 4 cases, his presentation, diagnosis, treatment and evolution was analyzed.

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.

Aggressive form of thyroglossal duct cyst carcinoma: role of ablative dose of Iodine-131

Ectopic thyroid tissue carcinoma is very rare and has usually good prognosis. It could arise in 1 percent of thyroglossal duct cysts (TDC), the most common nonodontogenic cysts that occur in the neck, which results from a failure in obliterating the embryogenic duct produced during thyroid migration. TDC is most often diagnosed during the childhood but may be discovered later in adult age. In most of the cases reported in the literature, thyroid carcinoma arising in the TDC is limited to the cyst without local extension and its efficient treatment consist of the surgical removal of the cyst by Sistrunk's operation. However, some controversies remain regarding the indication of total thyroidectomy when thyroid investigations are normal. Cases of aggressive thyroid carcinomas of the TCD with metastatic cervical lymph nodes are exceptional, mainly when histological findings of the thyroid gland are normal. We report a case of an aggressive form of a thyroglossal duct cyst carcinoma complicated with several infiltrated cervical lymph nodes but normal thyroid gland. The therapeutic strategy adopted in this case shows the decisive role of the post-operative ablative dose of Iodine-131 both for treatment and staging of aggressive form of thyroid carcinoma arising in thyroglossal duct cyst.

Thyroglossal duct cyst: a descriptive study of 41 cases

To describe the clinical presentations and site distribution of the thyroglossal duct cyst. This descriptive study was conducted at the Department of ENT District Headquarter Hospital Timergara from May 2001 to December 2007. The various presentations and management options were observed and documented using a semi structured proforma. Complications or recurrences, if any, were noted. A total of 41 cases of thyroglossal duct cyst with a mean age of 16. 7 +/- 17.49 years were included in the study. There were nineteen female and twenty two male patients. There were 9 recurrent and 32 cases. Forty patients presented with midline cystic swelling that moved with protrusion of tongue, seven with sore throat, 4 with dysphagia and 3 with globus. Forty [97.57] cases were central [9 [21.97%] suprahyoid and 31 [75.60%] infrahyoid] and 01 [2.43%] presented with cystic swelling on left side of the. neck All the cases were subjected to sistrunk operation. The most common presentation of thyroglossal duct cyst is a midline cystic swelling that moves with tongue protrusion. Thyroglossal duct cyst is present centrally in most of the cases

Carcinoma papilar en quiste del conducto tirogloso: reporte de dos casos / Papillary carcinoma in a thyroglossal duct cyst: report of two cases

Thyroglossal duct cyst is the most common congenital anomaly of thyroid gland development. However, papillary carcinoma is described only in 1-2 percent of cases and the clinical appearance is indistinguishable from a benign thyroglossal duct cyst. We report two females aged 15 and 27years consulting for a cervical mass. In both, a solid cystic lesion was found and excised using the Sistrunk procedure. The biopsy disclosed a papillary carcinoma in both. The postoperative evolution of both patients was uneventful.

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

Carcinoma papilífero em cisto do ducto tireoglosso: a tireoidectomia é necessária? / Papillary carcinoma of thyroglossal duct cyst: is thyroidectmy necessary?

Introdução: o cisto do ducto tireoglosso (CDT) é a doença congênita mais freqüente na região cervical. A presença de neoplasia maligna associada a esse cisto é pouco comum e de difícil diagnóstico pré-operatório. Objetivo: apresentar a experiência com carcinoma papilífero em CDT. Pacientes e Método: foram revistos 35 pacientes consecutivos submetidos à ressecção de CDT e estudados três cssos de carcinoma papilífero dentro do cisto, com análise do tratamento dos mesmos. Resultados: a incidência de carcinoma papilífero foi de 8,5% dos cistos nessa série, sendo duas mulheres e um homem e idade média de 27,3 anos (variação de 25 a 32 anos). Dois pacientes tiveram diagnóstico após cirurgia de Sistrunk e um apresentava biópsia aspirativa por agulha fina pré-operatória sugestiva de neoplasia. Todos os casos foram conduzidos com tireoidectomia total, um deles pela técnica vídeo-assistida, com pesquisa de corpo inteiro com I131 após a cirurgia. Em um paciente, foi encontrada neoplasia prim[aria na tireóide. Conclusão: o carcinoma papilífero em CDT é pouco freqüente. Embora o tratamento seja controverso, nosso ponto de vista é que a tireoidectomia total deva ser indicada, complementando a ressecção do cisto devido à possibilidade de tratar-se de tumor metástico e para facilitar o seguimento posterior. A técnica vídeo-assistida pode ser utilizada para realizar a tireoidectomia total por tratar-se, em geral, de glândulas de tamanho normal

Introduction: the Thyroglossaal duct cyst(TDC) is the most common congenital disease of the cervical region. The presence of associated malignant neoplasm in the cyst is uncommon and is difficult to perform the preoperative diagnosis. Objective: to present our experience with papillary carcinoma in the TDC. Patients and Methods: we reviewed 35 consecutive patients submited to TDC resection with three cases of papillary carcinoma in the cyst and analyzed the treatment. Results: the incidence in this serires was 8.5% of papillary carcinoma in the cysts, with two women and one man, whose mean age was 27.3 years (range, 25 to 32). Two patients were diagnosed after the Sistrunk procedure and one had preoperative fine needle aspiration biopsy suggestive of neoplasm. All patients underwnt complementary total thyrodectomy, one of them underthe videoassisted technique, and total body scintigraphy. In one patient, papillary carcinoma was found in the thyroid gland. Conclusion: the papillary carcinoma in TDC is an uncommon entity. The treatment is controversal, but in our pont of view the total thyroidectomy is indicated as a complement to the cyst resection because it can be metastatic, and to facilitate the follow-up. The videoassisted technique may be used to perform the total thyroidectomy because the glands have commonly normal size

Tratamiento quirúrgico ambulatorio del quiste del conducto tirogloso en el paciente pediátrico, Hospital Provincial Universitario Carlos Manuel de Céspedes Bayamo, Granma, Cuba / Ambulatory surgical treatment of the thyroglossal duct cyst in the pediatric patient, Province University Hospital Carlos Manuel de Cespedes Bayamo, Granma, Cuba

Se realizó una investigación observación al, retrospectiva y descriptiva de 80 pacientes con diagnóstico clínico e histológico de quistes del conducto tirogloso tratado ambulatoriamente. Con el objetivo de mostrar los resultados de este método en pacientes pediátricos y valorar los factores que influyeron en el tiempo de estadía. La edad fue inferior a los diez años en 20 por ciento de la serie estudiada. Todos los pacientes acudieron al hospital el día de la operación La cirugía empezó antes de la 1PM en 100 por ciento de los casos. El tiempo medio de anestesia fue de 70 minutos y el tiempo medio quirúrgico fue de 50 minutos. La técnica de Sistrunk fue realizada en 92,5 por ciento de los casos. Los factores que significativamente impactaron en el tiempo de estadía fueron el uso de drenaje y los signos postoperatorios inestables. El seguimiento mínimo de los pacientes fue de un año. Ocho pacientes mostraron recidivas y fueron reintervenidos a los 10 meses. La cirugía ambulatoria para la exeresis del quiste del conducto tirogloso es segura con el paciente adecuado. La planificación para la cirugía ambulatoria se presento usando técnicas quirúrgicas meticulosas, y evitando drenajes cuando la hemostasia fue adecuada.

An observation retrospective, and descriptive investigation of 80 patients with clinical and histopalogycal diagnosis of cysts of the thyroglossal duct, who recived ambulatory care. The goal of this estudy was to show the results of this procedure in operated pediatric patient and to value the factors that influrnced in the period of stay. The age was under 10 years in 20 % of the studied group.All patients went to the hospital on the day of their surgery. It began before 1PM in 100% of the cases. The mean time of anaesthesia was 70 minutes and the surgical 50 minutes. Sistrunk technique was performed in 92.5% of the cases.These factores that determined mainly the stay period were the use of drainage and unstable postoperative signs. The minimun follow-up of the patients lasted one year. Eight patients had relapse and received surgical treatment 10 month later. Ambulatory surgery for excision of the cyst in the thyroglossal duct can be safe with the adequate patient. Planning for ambulatory surgery should begin the day before, using careful surgical procedure, and avoiding drainage when hemoistasis is adequate.

Papillary thyroid carcinoma formation in a thyroglossal cyst: a case report

Thyroglossal cyst rarely presents with carcinoma formation in the remnants of the thyroid gland. We report a 40 year old male with papillary thyroid carcinoma formation in a thyroglossal cyst. The patient underwent surgical intervention for the cyst. His pathology was positive for thyroid carcinoma and he underwent complete thyroidectomy with postoperative radioactive iodine treatment. His follow up revealed no evidence of recurrence
