RESUMEN

Background: Thyroglossal duct cyst (TGDC) is the most common congenital neck mass among the pediatric population. Less than 10% of the cases occur in adults. The standard of care for TGDC is surgical treatment with the Sistrunk procedure via a traditional transverse cervicotomy. This technique involves the resection of the cyst with its tract and the central portion of the hyoid bone body to avoid recurrence. The transoral vestibular approach has gained popularity as an alternative approach to open neck surgery in order to eliminate the transcervical scar associated with these procedures. Methods: We describe a case of an endoscopic Sistrunk procedure performed by the transoral vestibular approach. A scoping review of the transoral endoscopic vestibular approach Sistrunk procedure (TEVAS) was performed. The PubMed, Medline, Cochrane, Lilacs, Scielo, Mary Ann Libert and Scopus databases were systematically searched by using a Medical Subject Heading (MeSH)-optimized search strategy. The selection of papers followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines after setting inclusion and exclusion criteria. Results: The case was successful and without complications. Five studies were included in the final analysis for this review. Conclusions: This novel approach to the Sistrunk procedure is an effective alternative way to treat TGDC in selected patients who are motivated to avoid a visible neck scar.

RESUMEN

Introduction: We introduce the third case reported in the literature of an atypical presentation of pleomorphic adenoma located in the nasal vestibule of a young patient who assisted at our clinic. Case Report: A young man with no important medical history consulted due to a painless mass-type slow-growth lesion associated with right nasal obstruction. He underwent surgical management and complete resection of the mass. The pathological study revealed a pleomorphic adenoma, confirmed by immunohistochemistry. Conclusion: This case confirms that pleomorphic adenomas can occur anywhere in the head and neck, even in areas without upper air-digestive tract mucosa.

RESUMEN

Abstract Introduction: The purposes of our study were to describe the distribution of diagnoses in a series of 273 patients over 65 years of age who presented for neck masses and to identify semiological fea tures associated with malignancy. Methods: Neck masses were categorized as congenital lesions (n = 7, 3%, 95% CI: 1%- 5%), inflammatory masses (n = 67, 25%, 95% CI: 19%- 30%), benign neoplasms (n = 77, 28%, 95% CI: 23%- 34%), and malignant neoplasms (n = 87, 32%, 95% CI: 26%- 38%). Results: A group of patients had discontinued care and, consequently, a definitive diagnosis could not be reached (n = 35, 12%). Age (OR 1.06, 95% CI 1.00-1.12), male sex (OR 2.35, 95% CI 1.11-4.96), prior history of cancer (OR 2.66, 95% CI 1.02-6.92), mass fixation to skin or deep tissues (OR 4.87, 95% CI 2.20-10.76), and the involvement of multiple cervical lymph node levels (OR 4.15, 95% CI 1.64-10.51) were identified as semiological features associated with malignancy. Conclusion: In the case of a neck mass in an elderly patient, its neoplastic origin should be strongly suspected.

Resumen Introducción: El objetivo de nuestro estudio fue describir la distribución de diagnósticos en una serie de 273 pacientes mayores de 65 años que consultaron por masas cervicales e identificar características semiológicas asociadas a malignidad. Métodos: Las masas cervicales fueron categorizadas como lesiones congénitas (n = 7, 3%, 95% CI: 1%- 5%), masas de origen inflamatorio (n = 67, 25%, 95% CI: 19%-30%), neoplasias benignas (n = 77, 28%, 95% CI: 23%- 34%) y neoplasias malignas (n = 87, 32%, 95% CI: 26%-38%). Resultados: Un grupo de pacientes discontinuó el tratamiento y en consecuencia no fue posible alcanzar un diagnóstico defini tivo (n = 35, 12%). La edad (OR 1.06, 95% CI 1.00-1.12), el sexo masculino (OR 2.35, 95% CI 1.11-4.96), los antecedentes de cáncer (OR 2.66, 95% CI 1.02-6.92), la fijación de la masa a los planos profundos o a piel (OR 4.87, 95% CI 2.20-10.76) y la afectación de más de un nivel ganglionar del cuello (OR 4.15, 95% CI 1.64-10.51) fueron identificados como características semiológicas asociadas a malignidad. Conclusión: En presencia de una masa cervical en un paciente adulto mayor debe existir una fuerte sospecha de origen neoplásico.

RESUMEN

Schwannomas are typically solitary, well-encapsulated, benign tumors running along or attached to a nerve. An intradural-extramedullary cervical spinal schwannoma, which first manifests as a swelling in the anterior neck, has not been reported to the best of our knowledge. We present the case of a 69-year-old patient complaining of a gradually worsening painful left cervical swelling for over 8 years. First, a posterior spinal midline approach was performed for the resection of the tumor and the tumor portion in the vertebral canal was totally removed. The second operation, the anterolateral approach, was planned to be executed in a second surgical session. The patient was discharged from the hospital without neurological deficits. Histopathological diagnosis was a schwannoma. The first aim of surgery is to treat neurological deficits in patients with cervical intraspinal schwannomas with/without extension into the extravertebral paravertebral neck regions. The surgical strategy combines the posterior midline and the anterolateral cervical approaches in the same session or at different times.

Schwannomas são tipicamente tumores solitários, bem encapsulados e benignos que correm ao longo ou aderem a um nervo. Até onde sabemos, um schwannoma espinhal cervical intradural-extramedular que se manifesta pela primeira vez como um inchaço na região anterior do pescoço não foi relatado. Apresentamos o caso de um paciente de 69 anos com queixa de inchaço cervical esquerdo doloroso de piora gradual há mais de 8 anos. Primeiramente, uma abordagem da linha média da coluna vertebral posterior foi realizada para a ressecção do tumor, e a porção do tumor no canal vertebral foi totalmente removida. A segunda operação, via anterolateral, foi planejada para ser realizada em uma segunda sessão cirúrgica. O paciente recebeu alta hospitalar sem déficits neurológicos. O diagnóstico histopatológico foi um schwannoma. O primeiro objetivo da cirurgia é tratar déficits neurológicos em pacientes com schwannomas intraespinhais cervicais com/sem extensão para as regiões extravertebrais do pescoço paravertebral. A estratégia cirúrgica combina a abordagem da linha média posterior e a abordagem anterolateral cervical na mesma sessão ou em momentos diferentes.

RESUMEN

Abstract Objective: Several clinical practice guidelines have been produced and disseminated for the evaluation of a neck mass. However, to date, the quality and methodologic rigor of these clinical practice guidelines have not been appraised. Therefore, this study set out to identify and assess the methodologic quality of national and international guidelines for the evaluation and management of neck masses in adults. Methods: We conducted a comprehensive search of EMBASE, MEDLINE/PubMed, SCOPUS and grey literature sources until September 2020. The quality of these guidelines was assessed by four reviewers using the Appraisal of Guidelines for Research and Evaluation, 2nd edition (AGREE II). Domain scores were considered acceptable quality if they scored >60%, and Intraclass Correlation Coefficients (ICC) were calculated to assess agreement among the appraisers. Results: Seven guidelines were assessed for evaluation. Among these, only the American Academy of Otolaryngology (AAO), Cancer Care Manitoba (CCMB), and the American Society of Clinical Oncology (ASCO) achieved an overall rating of ‟high". The remaining four guidelines achieved ratings of either ‟average" or ‟low". The ‟Scope and Purpose" domain achieved the highest mean score (94.4%±5.0%), and lowest was ‟Applicability" (51.5%±29.2%). ICC analysis showed substantial to very good agreement across all domains (0.75-0.98). Conclusion: These findings highlight the variability in methodologic quality of guidelines for the evaluation and management of adult neck mass. The results from this analysis highlight the need to improve guidelines development process for this topic and may guide the selection and use of these guidelines in clinical practice.

Resumo Introdução: Várias diretrizes de práticas clínicas foram produzidas e divulgadas para a avaliação de massa cervical. Porém, até o momento, a qualidade e o rigor metodológico dessas diretrizes de práticas clínicas não foram avaliados. Objetivo: Identificar e avaliar a qualidade metodológica das diretrizes nacionais e internacionais para a avaliação e tratamento de massas cervicais em adultos. Método: Fizemos uma pesquisa abrangente das fontes de dados Embase, Medline/PubMed, Scopus e literatura cinza até setembro de 2020. A qualidade dessas diretrizes foi avaliada por quatro revisores com a 2a edição do Appraisal of Guidelines for Research and Evaluation (AGREE II). Os escores dos domínios foram considerados de qualidade aceitável se pontuassem >60% e os coeficientes de correlação intraclasse (Intraclass correlation coefficient - ICC) foram calculados para avaliar a concordância entre os avaliadores. Resultados: Sete diretrizes foram investigadas para avaliação. Entre elas, apenas a American Academy of Otolaryngology (AAO), o Cancer Care Manitoba (CCMB) e a American Society of Clinical Oncology (ASCO) obtiveram uma classificação geral ‟alta". As quatro diretrizes restantes obtiveram classificações ‟media" ou ‟baixa". O domínio ‟Escopo e objetivo'" obteve o maior escore médio (94,4% ± 5,0%) e o domínio ‟Aplicabilidade" obteve o menor escore (51,5%±29,2%). A análise ICC mostrou concordância substancial a muito boa em todos os domínios (0,75-0,98). Conclusão: Esses achados destacam a variabilidade na qualidade metodológica das diretrizes para avaliação e tratamento de massa cervical em adultos. Os resultados dessa análise destacam a necessidade de melhorar o processo de desenvolvimento de diretrizes para esse tópico e podem orientar a seleção e o uso dessas diretrizes na prática clínica.

RESUMEN

Introdução: Os cistos branquiais são tumores congênitos laterais, resultantes de defeitos de desenvolvimento embrionário que afetam os arcos branquiais.1 As anomalias congênitas cervicais são mais comumente diagnosticadas nos primeiros anos de vida. Objetivo: Informar, discutir e analisar condutas para tratamento desse tipo de cisto congênito. Método:Relato de caso e análise de dados, diagnósticos e conduta baseada na literatura referente a Cisto Branquial da 4° Fenda. Resultados:Os cistos podem se manifestar tardiamente, mas as fístulas são, quase sempre, diagnosticadas ao nascimento ou na infância.São extremamente raros, estima-se que 95% das anomalias das fendas branquiais sejam da 2ª fenda; das 5% restantes, quase todas são da 1ª ou 3ª fenda.O diagnóstico é primariamente clínico, mas a ultrassonografia pode auxiliar no diagnóstico diferencial de um cisto branquial. O tratamento das anomalias branquiais é a excisão cirúrgica. Lactente sexo feminino, 9 meses de idade em acompanhamento de cisto branquial com conduta conservadora. O surgimento da massa se deu logo ao nascimento, havendo drenagem espontânea do cisto para o esôfago alguns dias depois. Após nove meses paciente retorna devido aumento progressivo da lesão que correlacionando com exame físico, exames de imagem levaram ao diagnóstico de cisto de 4º fenda branquial. Realizada cirurgia para remoção de Cisto juntamente com retirada de lobo esquerdo da tireoide (tireoidectomia parcial). Conclusão:Após a exerese da lesão paciente evoluiu satisfatoriamente sendo encaminhado para enfermaria e posteriormente alta com acompanhamento ambulatorial com pediatra geral.

Introduction: Branchial cysts are congenital tumors, resulting from embryonic defects that affect the branchial arches. Congenital cervical abnormalities are usually diagnosed in the first years of life. Objective: To inform, discuss and analyze treatment approaches for this type of congenital cyst. Method: Case report and analysis of data, diagnoses and approaches based on the literature addressing Fourth Branchial Cleft Cysts. Results: Cysts can manifest late, but fistulas are almost always diagnosed at birth or in childhood. They are extremely rare: it is estimated that 95% of branchial cleft anomalies involve the second cleft; of the remaining 5%, almost all arise from the first and third clefts. There are about 45 cases of fourth cleft cysts reported in the literature. The diagnosis is primarily clinical, but the ultrasound can be used for the differential diagnosis of a branchial cyst. Computed tomography will show air-fluid level in the anterior portion of the neck, in front of the thyroid and trachea, which may compress the trachea, causing respiratory distress in childhood. The treatment of branchial anomalies is surgical excision. A 9-month old female patient was being followed up after conservative treatment of a cervical mass (branchial cyst). The cyst appeared immediately after birth, but there was there was spontaneous drainage of the cyst into the esophagus a few days later. After nine months, the patient returned due to a progressive increase of the lesion, which, after physical examination and imaging exams, led to the diagnosis of a fourth branchial cleft cyst. A surgical procedure was performed to remove the cyst along with the left thyroid lobe (partial thyroidectomy). Conclusion: After the excision of the lesion, the patient made a good recovery. She was then referred to the infirmary and later discharged with outpatient follow-up by a general pediatrician.

RESUMEN

Resumen En adultos, una masa cervical detectada mediante examen físico o un estudio de imagen puede ser la única manifestación de un cáncer proveniente de cabeza y cuello. Un retraso en el diagnóstico repercute en el pronóstico de la enfermedad, por lo que debe haber un alto índice de sospecha. Las metástasis cervicales con primario desconocido (MCCPD) son tumores metastásicos en los que el estudio diagnóstico no logró identificar el sitio primario del cáncer, con una histología predominantemente de tipo escamosa. Según algunos estudios, el origen más frecuente resultó ser la orofaringe, incluyendo amígdala palatina y base de lengua. Factores de riesgo conocidos son edades avanzadas, consumo de tabaco y de alcohol. Actualmente, la infección por el virus del papiloma humano (VPH) está teniendo un rol cada vez más importante como factor de riesgo, formando parte de entre 20%-25% de los cánceres de cabeza y cuello. Al enfrentarse a un paciente con masa cervical es importante realizar una completa anamnesis y examen físico acucioso para detectar cualquier elemento sugerente de malignidad. Se debe complementar con nasofibroscopía para visualizar estructuras que no alcanzan a evaluarse en el examen habitual. También se puede orientar la búsqueda del primario desconocido en base a los patrones de drenaje linfático. Dentro del estudio complementario se puede comenzar con una tomografía computada (TC) y se puede considerar también el ultrasonido o un PET/TC. Si con esto aún no se logra definir el primario, continuar con una punción aspirativa con aguja fina (PAAF), luego biopsia core que consiste en tomar una muestra del centro de la lesión guiada por ecografía, si fuese necesario, incluyendo inmunohistoquímica para VPH; ambos estudios histológicos son preferibles en vez de una biopsia abierta debido al menor riesgo de diseminación y complicaciones. El siguiente paso incluye estudio endoscópico y biopsias bajo anestesia. El tratamiento de los pacientes con MCCPD, va a depender de factores relacionados con el estadio de la enfermedad: desde cirugía o radioterapia (RT) únicas, cirugía más RT, y en algunos casos quimioterapia. Se recomienda seguimiento clínico frecuente durante los primeros años y con imágenes dentro de los 6 primeros meses postratamiento.

Abstract In adults, a cervical mass detected by physical examination or an imaging study may be the only manifestation of cancer from the head and neck. A delay in the diagnosis affects the prognosis of the disease, so there must be a high index of suspicion. Cervical metastases from unknown primary tumor (CUP) are metastatic tumors in which the diagnostic study failed to identify the primary site of cancer, with predominantly squamous histology. According to some studies, the most frequent origin was the oropharynx, including palatine tonsil and tongue base. Known risk factors are advanced ages, tobacco and alcohol consumption. Currently, human papilloma virus (HPV) infection is playing an increasingly important role as a risk factor, being the cause of between 20-25% of cancers of the head and neck. When confronting a patient with cervical mass it is important to carry out a complete anamnesis and a thorough physical examination to detect any element suggestive of malignancy. Physical examination could be complemented with a flexible nasal endoscopic to evaluate structures that can not be evaluated in the habitual examination. The search for the unknown primary can also be oriented based on lymphatic drainage patterns. Within the complementary evaluations, one can start with a study of images such as computed tomography (CT) or magnetic resonance imaging (MRI) with contrast, and also could consider ultrasound or PET/CT. If the primary can not be defined yet, fine needle aspiration (FNAP) can be the next choice and then a core biopsy that consisting of taking a sample from the center of the ultrasound-guided lesion, if necessary, including immunohistochemistry for HPV; both histological studies are preferable to an open biopsy because of the lower risk of complications. The next step searching for the primary includes endoscopic study and biopsies under anesthesia. Regarding to the management of patients with CUP, it will depend on factors related to the stage of the disease: from surgery or radiotherapy (RT) only, surgery and RT, and in some cases chemotherapy. Frequent clinical follow-up is recommended during the first years and images within the first 6 months after treatment.

RESUMEN

Hemangioma is a common tumor, normally diagnosed in children, and accounting for almost 10% of benign neoplasms. A hemangioma arising from the wall of a vessel is rare, and must be differentiated from other vascular malformations of the same origin. We report a rare case of a hemangioma arising from the wall of an external jugular vein and discuss diagnostic work-up and management.

RESUMEN

Congenital teratoma is a rare condition and is a germ cell tumor composed of elements from one or more of the embryonic germ layers and contain tissues usually foreign to the anatomic site of origin. We report a case of a neck tumor diagnosed during pregnancy, initially thought to be a goiter. After birth the neck mass kept growing until it compressed the trachea and produced respiratory failure. The infant had a difficult tracheal intubation because of the compressing mass. The staff decided to surgically remove the neck mass. After that, the infant became eupneic. The histological analysis showed a mature teratoma with no atypias.

RESUMEN

OBJECTIVE: The involvement of the thyroid by tuberculosis (TB) is rare. Hypothyroidism caused by tissue destruction is an extremely rare report. Our aim was to report a patient with primary thyroid TB emphasizing the importance of diagnosis, despite the rarity of the occurrence. CASE REPORT: Women, 62 years old, showing extensive cervical mass since four months, referring lack of appetite, weight loss, dysphagia and dysphonia. Laboratorial investigation revealed primary hypothyroidism. Cervical ultrasound: expansive lesion in left thyroid lobe, involving adjacent muscle. Computed tomography scan: 13 cm diameter cervical mass with central necrosis. Fine needle biopsy: hemorrhagic material. Surgery: total thyroidectomy, left radical neck dissection and protective tracheotomy. The pathological examination showed chronic granulomatous inflammatory process with areas of caseous necrosis and lymph node involvement. The thyroid baciloscopy was positive. Pulmonary disease was absent. The patient was treated with antituberculosis drugs. CONCLUSIONS: Thyroid TB is not frequent, and should be considered as differential diagnosis of hypothyroidism and anterior cervical mass.

OBJETIVO: A tuberculose tiroidiana ocorre raramente. O hipotireoidismo decorrente da destruição tiroidiana é um relato raríssimo. Nosso objetivo foi descrever o caso de paciente com tuberculose tiroidiana primária e ressaltar a raridade e a importância da doença. RELATO DO CASO: Mulher, 62 anos, apresentando massa cervical extensa há quatro meses, associada à inapetência, à perda de peso, à disfonia e à disfagia. A investigação laboratorial mostrou hipotireoidismo primário. Ultrassonografia: lesão expansiva em lobo esquerdo, envolvendo musculatura subjacente. Tomografia computadorizada: massa heterogênea com centro necrótico, 13 cm de diâmetro. Biópsia por agulha fina: material serossanguinolento. Cirurgia: tireoidectomia, dissecção radical à esquerda e traqueostomia protetora. Exame anatomopatológico: processo inflamatório crônico granulomatoso com áreas de necrose caseosa e comprometimento linfonodal. Baciloscopia tiroidiana positiva. Ausência de comprometimento pulmonar. A paciente foi tratada com drogas antituberculosas. CONCLUSÕES: Tuberculose tireoidiana não é frequente, mas deve ser considerada como diagnóstico diferencial de hipotireoidismo e massa cervical anterior.
