ABSTRACT

La lesión del nervio laríngeo recurrente (NLR) es una de las complicaciones más severas en las tiroidectomías. La lesión unilateral genera trastornos disfónicos que se manifiesta por voz débil y una posición paramedial de la cuerda vocal afectada, mientas que la bilateral genera trastornos respiratorios, incluyendo la asfixia. Se ha estimado que la lesión del NLR en las tiroidectomías se encuentra entre un rango de 0.3%- 18.9%. Se ha visto que con el neuromonitoreo intraoperatorio ha disminuido la incidencia de lesión, aunque debemos tener en cuenta un factor muy importante a la hora de solicitarlo y utilizarlo, el económico. La tasa de lesión permanente del nervio laríngeo recurrente debe permanecer por debajo de 1 a 2 %. Sin embargo, existen circunstancias en las cuales los nervios están expuestos a un mayor riesgo y son muchos los factores involucrados en su mecanismo de lesión. Este artículo pretende hacer una revisión del tema enfatizando en la importancia de la preservación de la funcionalidad e integridad de ambos nervios laríngeos recurrentes.


Recurrent laryngeal nerve injury (RLN) is one of the most severe complications in thyroidectomies. Unilateral injury generates dysphonic disorders manifested by weak voice and a paramedial position of the affected vocal cord, while bilateral injury generates respiratory disorders, including suffocation. RLN injury in thyroidectomies has been estimated to be in the range of 0.3% - 18.9%. It has been seen that with intraoperative neuromonitoring the incidence of injury has decreased, although we must take into account a very important factor when requesting and using it, the economic one. The rate of permanent injury to the recurrent laryngeal nerve should remain below 1% to 2%. However, there are circumstances in which the nerves are exposed to greater risk and many factors are involved in their mechanism of injury. This article aims to review the subject, emphasizing the importance of preserving the functionality and integrity of both recurrent laryngeal nerves

ABSTRACT

El hipoparatiroidismo (hipoPTH) es una enfermedad infrecuente caracterizada por hipocalcemia y niveles inapropiadamente bajos o ausentes de parathormona. Presentamos el caso de un hombre de 25 años, deportista de alto rendimiento, con antecedente de hipoPTH secundario a tiroidectomía total dos años antes por cáncer papilar multifocal bilateral tiroideo, estadificado como T3 N1b M0, derivado por hipocalcemia sintomática. Presentaba calcemias promedio de 7mg%, síntomas de hipocalcemia en reposo y múltiples internaciones. Inicialmente, se optimizó tratamiento convencional con aporte de calcio vía oral hasta 12g/día, vitamina D y calcitriol, sin mejoría clínica ni bioquímica. Se descartaron malabsorción y complicaciones crónicas de hipoPTH. Se evidenció a través de cuestionario de salud SF-36 disminución de la calidad de vida. Se indicó sustitución con parathormona recombinante humana [rhPTH(1-84)] 50μg/día subcutánea con posterior ascenso a 75μg y reducción progresiva de la medicación por vía oral. Actualmente se encuentra asintomático, sin requerimiento de calcio ni vitamina D, mantiene calcemias de 9mg%, realiza actividad deportiva y demuestra marcada mejoría en la calidad de vida según cuestionario SF-36 (36-Item Short Form Health Survey).


Hypoparathyroidism (HypoPT) is a rare disease characterized by low calcium and inappropriately low circulating parathormone levels. We present the case of a 25-year-old high-performance athlete male, with history of HypoPT after total thyroidectomy for papillary thyroid carcinoma (T3 N1b M0) two years before, who was referred to our clinic for symptomatic hypocalcemia. The patient reported serum calcium average levels of 7mg%, presented symptoms of hypocalcemia at rest and had multiple hospital admissions. First, standard treatment was optimized by calcium supplementation up to 12g/d and active vitamin D, not showing clinical or biochemical improvement. Malabsorption and complications of chronic HypoPT were ruled out. The 36-Item Short Form Health Survey (SF-36) demonstrated an impaired quality of life (QoL). Full-length recombinant human parathyroid hormone [rhPTH(1-84)] therapy was started with 50μg/d subcutaneous, and later adjusted to 75μg/d and the oral treatment gradually decreased. Currently, he is asymptomatic, with serum calcium levels above 9mg%, without receiving oral medication. He performs sports activity and shows marked improvement in quality of life according to SF-36 questionnaire.

ABSTRACT

Heterotopic ossification has been described in papillary thyroid carcinoma in association with high incidence of extrathyroidal invasion, multifocality, lymph node metastasis, and older age. Nevertheless, it has not been described as a specific subtype of papillary thyroid carcinoma, because of its rarity. We described the case of an 80-year-old female patient, with familial history of papillary thyroid carcinoma. In the annual screening examination, she was diagnosed with thyroid nodules. The patient was submitted to a thyroidectomy because the fine needle aspiration cytology was positive for malignancy according to the Bethesda classification. The surgical specimen analyses showed a multifocal papillary carcinoma with one major lesion in the left lobe measuring 0.9 cm, and two small lesions (0.4 cm and 0.2 cm) in the right lobe. Only the biggest lesion in the right lobe had the osteoid matrix with rare osteoclasts and fat metaplasia with progenitor cells. There was perineural invasion, but vascular invasion was not identified. The margins were free and there was no extrathyroidal extension. In the left lobe there was an oncocytic nodule and a lipomatous follicular nodule. In recent years there has been a significant increase in the diagnosis of thyroid cancer, mainly because of the finding of microcarcinomas as a result of many requests for cervical image exams. Future studies may define (i) whether papillary thyroid carcinoma with heterotopic ossification is a true histological variant; (ii) the causes of that alteration; and (iii) eventual follow-up implications.

ABSTRACT

SUMMARY Thyroid carcinoma (TC) is rare in children, particularly in those aged < 10 years. Several studies have demonstrated a correlation between neoplasms and hyperinsulinemia and insulin resistance, which are often associated with a higher risk for and/or aggressiveness of the neoplasm. Congenital generalized lipodystrophy (CGL) with autosomal recessive inheritance is a rare disease and is characterized by the lack of adipose tissue, severe insulin resistance, and early metabolic disturbances. Here, we reported a rare case of a type 2 CGL in a girl who presented with a papillary TC (PTC) at the age of 7 years. She had no family history of TC or previous exposure to ionizing radiation. She had a generalized lack of subcutaneous fat, including the palmar and plantar regions, muscle hypertrophy, intense acanthosis nigricans, hepatomegaly, hypertriglyceridemia, severe insulin resistance, and hypoleptinemia. A genetic analysis revealed a mutation in the BSCL2 gene (p.Thr109Asnfs* 5). Ultrasound revealed a hypoechoic solid nodule measuring 1.8 × 1.0 × 1.0 cm, and fine needle aspiration biopsy suggested malignancy. Total thyroidectomy was performed, and a histopathological examination confirmed PTC with vascular invasion and parathyroid lymph node metastasis (pT3N1Mx stage). This is the first report to describe a case of differentiated TC in a child with CGL. Severe insulin resistance that is generally observed in patients with CGL early in life, especially in those with type 2 CGL, may be associated with this uncommon presentation of aggressive PTC during childhood.

ABSTRACT

ience in the management of differentiated thyroid carcinomas in a low- income country. Materials and Methods: We performed a retrospective study in our department where 21 cases of differentiated thyroid carcinomas were recorded from February 2001 to December 2010. Results: We performed 334 thyroidectomies for 326 patients. Of this group, 21 differentiated thyroid carcinomas were diagnosed. Differentiated thyroid carcinomas represented 6.4% of all thyroid neoplasm managed during the same period (n=326). Median age was 44 years (range 13 - 75 years). Male to female ratio was 1:20. Six (6) patients underwent primary hemithyroidectomy in other institutions while the fifteen left were entirely managed in our clinic. Of them, one patient was referred with positive fine needle aspiration cytology for papillary thyroid carcinoma (incidental detection by fine needle aspiration biopsy) and another had history of sinus pyriform fistula. Pathology of surgical specimens showed 13 cases of papillary thyroid carcinomas and 8 cases of follicular thyroid carcinomas with association to Hashimoto thyroiditis and Grave's disease in respectively in 1 case. Twenty cases were incidentally discovered by thyroid surgery and undergone completion thyroidectomy with prophylactic central neck dissection, completion thyroidectomy alone, modified lateral neck dissection alone and surveillance respectively in 13, 1, 1 and 6 cases. Complications of thyroid surgery were bilateral recurrent laryngeal nerve paralysis and hematoma respectively in 1 case. Median hospital stay was 5 days ranged from 3 to 15 days. During the follow-up period, most of our patients were lost of follow-up. Conclusion: Management guidelines of differentiated thyroid carcinomas are well established but not applicable to low- income country for several reasons. National guidelines, based on further researches, must then be implemented to improve our practice

ABSTRACT

La presencia de metástasis a distancia en el cáncer diferenciado de tiroides es un hecho infrecuente que ocurre en menos del 10% de los pacientes. Cuando sucede, la supervivencia a 10 años disminuye significativamente. La curación es el objetivo primario, pero dado que 2 tercios de los tumores metastásicos se volverán radiorrefractarios en su evolución, la finalidad terapéutica es estabilizar la enfermedad y tratar sus síntomas. En la última década, el manejo de estos pacientes cambió radicalmente con el advenimiento de las terapias con blancos moleculares. El objetivo de esta revisión es describir las características de los pacientes con cáncer diferenciado de tiroides que presenten metástasis a distancia, la supervivencia global, los métodos diagnósticos utilizados, y los tratamientos locales y sistémicos disponibles.


Distant metastases occur in less than 10% of patients with differentiated thyroid carcinoma. In these patients, overall survival at 10 years is considerably reduced. Whereas cure is the initial goal of treatment, stabilisation of the disease and management of symptoms have become the primary objective in many patients with persistent radio-iodine refractory progressive disease. In the last decade, several targeted therapies have shown encouraging results in patients with advanced disease. The objective of this review is to describe the characteristics, diagnosis, overall survival, and the local and systemic available treatments for patients with distant metastases from differentiated thyroid cancer.

ABSTRACT

Las metástasis ganglionares regionales del cuello están presentes en un gran porcentaje de los casos con CPT. Sin embargo, en varios trabajos se pudo observar como no todo compromiso ganglionar tiene igual impacto en la evolución de dicha patología. Recientemente en Argentina, Chile y Brasil se modificaron las guías del manejo del CDT y estas recomiendan una estratificación de riesgo y abordaje terapéutico diferente según el número, el tamaño y la extensión del compromiso ganglionar. En esta monografía se analizaron las características de las metástasis ganglionares y su impacto en la evolución del CDT y esto fue realizado previamente a la reciente publicación de las nuevas guías de la ATA. Dada esta situación, se incorporaron a la monografía original algunos aspectos de las guías de ATA


Cervical lymph node metastases are usually present in a high number of cases with papillary thyroid carcinoma. However, many studies have shown that not all lymph node metastases have the same impact on the outcome of this disease. Argentina, Chile, and Brazil have recently changed their differentiated thyroid carcinoma (DTC) guidelines and recommend a different ranking of risk and therapeutic approach according to the number, size, and extension of lymph node metastasis. An analysis of lymph node metastases is presented in this article, which includes their characteristics and impact on DTC. As this analysis was made before the latest publication of the new American Thyroid Association guidelines, some aspects of these guidelines have also been included

ABSTRACT

Although hypothyroidism is associated with an increased prevalence of psychiatric manifestations, myxedema madness is rarely observed. We report the case of a 62-year-old woman with no prior history of psychiatric disorders, who presented to the emergency department with psychomotor agitation 6 weeks after total thyroidectomy for papillary thyroid cancer. Serum thyroid stimulating hormone (TSH) on admission was 62.9 mIU/L and free T4 was < 0.35 ng/dL, indicating severe hypothyroidism. After ruling out other possible causes, the diagnosis of myxedema madness was considered; hence, antipsychotic drug treatment and intravenous levothyroxine were prescribed. Behavioral symptoms returned to normal within 4 days of presentation, while levels of thyroid hormones attained normal values 1 week after admission. Recombinant TSH (Thyrogen®) was used successfully to prevent new episodes of mania due to thyroid hormone withdrawal in further controls for her thyroid cancer. This case illustrates that myxedema madness can occur in the setting of acute hypothyroidism, completely reverting with levothyroxine and antipsychotic treatment. Recombinant TSH may be a useful tool to prevent myxedema madness or any severe manifestation of levothyroxine withdrawal for the follow-up of thyroid cancer.

ABSTRACT

Advanced radioactive refractory and progressive or symptomatic differentiated thyroid carcinoma (DTC) is a rare condition. Sorafenib was recently approved for the treatment of these patients. We present the case of a 67 year old woman diagnosed with DTC who underwent a total thyroidectomy with central, lateral-compartment neck dissection and shaving of the trachea and esophagus due to tumor infiltration. A local recurrence was detected 14 months later requiring, additionally, two tracheal rings resection. The patient received a cumulative 131I dose of 650 mCi and developed dysphagia and dyspnea 63 months after initial surgery. A 18FGD-PET/CT showed progression of the local mass associated to hypermetabolic pulmonary nodules. Sorafenib 800 mg/day was then prescribed. A dose reduction to 400 mg/day was necessary due to grade 3 thrombocytopenia that appeared four months after drug prescription. Platelet count went to normal after this dose reduction. Five months after initiation of sorafenib, a partial response of the local mass with significant intra-tumoral necrosis was observed. We conclude that sorafenib is a valid option for locally advanced DTC and that the platelet count should be evaluated regularly because it seems that thrombocytopenia might be more frequently observed in DTC than in other types of tumors.

ABSTRACT

Resistance to thyroid hormone (RTH) is a rare autosomal dominant hereditary disorder. Here in, we report two patients with RTH in whom differentiated thyroid cancer was diagnosed. Two patients were admitted to our clinic and their laboratory results were elevated thyroid hormone levels with unsuppressed TSH. We considered this situation thyroid hormone resistance in the light of laboratory and clinical datas. Thyroid nodule was palpated on physical examination. Thyroid ultrasonography showed multiple nodules in both lobes. Total thyroidectomy was performed. The pathological findings were consistent with papillary thyroid microcarcinoma. BRAFV600E mutation analysis results were negative. RTH is very rare and might be overlooked. There is no consensus on how to overcome the persistently high TSH in patients with RTH and differentiated thyroid cancer (DTC). Further studies are needed to explain the relationship between RTH and DTC which might be helpful for the treatment of these patients.

ABSTRACT

Medullary thyroid carcinoma (MTC) may rarely present with paraneoplastic syndromes. Among the most frequent ones are the appearance of diarrhea and ectopic Cushing syndrome (ECS). The ECS in the context of MTC is usually present in patients with distant metastatic disease. The use of drugs such as ketoconazole, metyrapone, somatostatin analogs and etomidate have been ineffective alternatives to control hypercortisolism in these patients. Bilateral adrenalectomy is often required to manage this situation. Recently, the use of tyrosine kinase inhibitors has been shown to be a useful tool to achieve eucortisolism in patients with metastatic MTC and ECS. We present a patient with sporadic advanced persistent and progressive MTC with lymph node and liver metastases, which after 16 years of follow-up developed an ECS. After one month of 300 mg/day vandetanib treatment, a biochemical and clinical response of the ECS was achieved but it did not result in significant reduction of tumor burden. However the patient reached criteria for stable disease according to response evaluation criteria in solid tumors (RECIST 1.1) after 8 months of follow-up.

ABSTRACT

INTRODUCTION: Papillary carcinoma is the most common malignant thyroid neoplasm. The effect of the concurrent presence of Hashimoto's thyroiditis and papillary thyroid carcinoma remains controversial. OBJECTIVE: To evaluate the association between Hashimoto's thyroiditis and clinicopathological parameters in thyroid papillary carcinoma cases, based on an historical institutional cohort analysis. METHODS: Cross-sectional study obtained from a historical cohort, including all cases submitted to thyroidectomy for papillary thyroid carcinoma in a single institution during an 11-year period study. RESULTS: A total of 417 patients with papillary thyroid carcinoma were enrolled; 148 (35.4%) also had Hashimoto's thyroiditis. A female predominance among cases associated to Hashimoto's thyroiditis was observed. The thyroid tumor, in cases associated with Hashimoto's thyroiditis, had a smaller mean diameter, lower frequency of extra-thyroid extension, and earlier clinicopathological staging. CONCLUSIONS: A high proportion of papillary thyroid carcinoma cases are associated with Hashimoto's thyroiditis. There are associations among these cases with several histopathological factors already recognized for their prognostic value, which by themselves could impact outcomes. .


INTRODUÇÃO: O carcinoma papilífero é a neoplasia maligna mais comum da tireóide. O efeito da coexistência da tireoidite de Hashimoto (TH) no prognóstico do carcinoma papilífero da tireóide (CPT) permanece controverso. OBJETIVO: Avaliar a associação entre TH e parâmetros clínico-patológicos entre pacientes com diagnóstico de carcinoma papilífero da tireóide obtidos através da análise de uma série histórica institucional. MÉTODO: Coorte transversal com base em uma coorte histórica, envolvendo todos os casos submetidos à tireoidectomia total por motivo de carcinoma papilífero, realizadas na mesma Instituição ao longo de 11 anos. RESULTADOS: Um total de 417 pacientes foram incluídos no estudo, estando 148 (35,4%) associados à TH. Observamos preponderância de mulheres entre os casos associados à TH. Esses casos se apresentaram com menor média de diâmetro tumoral, menor frequência de comprometimento extra-tireoidiano e estadiamento clínico-patológico mais precoce. Conclusões: Um percentual expressivo de casos de CPT apresenta-se associado à TH. A associa ção entre esses casos com vários fatores histopatológicos já reconhecidos por seu valor prognóstico, pode, por si só, influenciar no desfecho desses pacientes. .

ABSTRACT

PURPOSE: To report clinical characteristics of thyroid-associated ophthalmopathy (TAO) in patients who previously underwent total thyroidectomy for thyroid cancer or a benign mass of the thyroid. MATERIALS AND METHODS: Of the patients who were diagnosed with TAO from March 2008 to March 2012, we performed a retrospective chart review on those who had undergone total thyroidectomy for thyroid cancer or a benign mass of the thyroid before the occurrence of ophthalmopathy. RESULTS: Of the 206 patients diagnosed with TAO, seven (3.4%) met the inclusion criteria. The mean age of the subjects was 47.4 years, and all were female. Six patients were diagnosed with papillary thyroid cancer, and one was diagnosed with a benign mass. The duration between total thyroidectomy and onset of TAO ranged from 3-120 months (median 48 months). Ophthalmic manifestations varied among cases. Except for the patient who was diagnosed with a benign mass, all patients showed hyperthyroid status and were under Synthroid hormone treatment at the time of TAO development. Five of these six patients had positive levels of thyroid-stimulating hormone (TSH) receptor autoantibodies. CONCLUSION: TAO rarely develops after total thyroidectomy, and the mechanism of TAO occurrence is unclear. However, most patients showed abnormalities in thyroid function and TSH receptor autoantibodies.

ABSTRACT

Background: Brown tumors of bones are an uncommon manifestation of hyperparathyroidism. Case report: We report a 35 years old male presenting with pain and paresis of the left superior limb. Part of his humerus was excised due to a diagnosis of a giant cell tumor. He was admitted again to the hospital due to pelvic pain, malaise and constipation. A right cervical nodule was found. Laboratory evaluation confirmed the presence of a hyperparathyroidism. The biopsy of the pelvic lesion disclosed a brown tumor. The patient was subjected to a parathyroidectomy and the pathological study of the surgical piece showed a right parathyroid adenoma and a right thyroid papillary micro carcinoma. In the postoperative period the patient had a hungry bone syndrome, which was adequately treated.


Introducción: La paratohormona es una hormona encargada de la homeostasis del calcio, el hiperparatiroidismo es una patología con manifestaciones renales y óseas, el Tumor Pardo es una rara presentación de esta enfermedad. Caso clínico: Hombre de 35 años con dolor y paresia en extremidad superior izquierda, fue resecado parte del húmero por un diagnóstico de Tumor de Células Gigantes; reingresa con dolor pélvico derecho, malestar general, astenia y estreñimiento. Se descubre un nódulo cervical derecho e hipersensibilidad en la pelvis derecha. Los exámenes de laboratorio muestran hiperparatiroidismo; la biopsia de la lesión pélvica es diagnóstica de Tumor Pardo, encontrándose además una hipercaptación paratiroidea derecha. Operado, el diagnóstico histopatológico fue: Adenoma paratiroideo derecho y un micro carcinoma papilar tiroideo; en el post-operatorio desarrolló un Síndrome de Bone Hunger, el cual fue superado y dado de alta. Discusión y conclusiones: El Tumor Pardo no es una verdadera neoplasia; producido por intensa actividad osteoclástica, tiene características histológicas y radiológicas inespecíficas y su diagnóstico se realiza por datos clínicos y bioquímicos.

ABSTRACT

Subacute thyroiditis (SAT) association with thyroid carcinoma has been rarely reported in the literature. We present a patient with SAT and papillary thyroid cancer that was suspected by ultrasonographic evaluation (US) following SAT treatment. A fifty-four-year old female patient referred to our department due to tachycardia, jitteriness and pain in cervical region for the past one month. SAT diagnosis was established by physical examination, laboratory and ultrasonographic findings. After treatment, control thyroid US revealed regression of the hypoechogenic regions seen in both lobes, and a previously unreported hypoechogenic lesion with microcalcification focus that had irregular borders and was not clearly separated from the surrounding parenchyma located in the posterior aspect of the lobe (Elasto score: 4, Strain index: 7.08). Fine needle aspiration biopsy was taken from this nodule; cytology was assessed to be compatible with papillary thyroid carcinoma. Postsurgical pathology evaluation showed a papillary microcarcinoma. SAT may produce ultrasound changes that obscure the coexistence of papillary carcinoma. We recommend that patients with SAT have ultrasonography after they recover. Hypoechogenic regions bigger than 1 cm that are present in the follow-up post-therapy US should be assessed by biopsy.


A associação da tireoidite subaguda (TSA) com o carcinoma de tiroide foi raramente relatada na literatura. Apresentamos uma paciente com TSA e tumor papilar de tiroide suspeito na ultrassonografia (US) após o tratamento para a TSA. Uma mulher de 54 anos de idade foi encaminhada ao nosso departamento com taquicardia, agitação e dor na região cervical, com duração de 1 mês. O diagnóstico de TSA foi estabelecido pelo exame físico, e pelos achados laboratoriais e ultrassonográficos. Depois do tratamento, o US para controle da tiroide mostrou regressão das regiões hipoecoicas vistas em ambos os lobos e uma lesão hipoecoica anteriormente não observada com focos de microcalcificação, bordas irregulares, não claramente separada do parênquima circundante e localizada na região posterior do lobo. (Escore elástico: 4, índice de deformação: 7,08). Foi feita uma biópsia do nódulo por meio de aspiração por agulha fina. A citologia mostrou-se compatível com um carcinoma papilar de tiroide. A avaliação pós-cirúrgica mostrou um microcarcinoma papilar. A TSA pode produzir alterações ultrassonográficas que obscurecem a coexistência de carcinoma papilar. Recomendamos que pacientes com TSA passem por exame ultrassonográfico após a recuperação. Regiões hipoecoicas maiores que 1 cm encontradas no US para acompanhamento pós-tratamento devem ser avaliadas por biópsia.
