Tumores de parótida en población pediátrica: 10 años de experiencia / PAROTID TUMORS IN PEDIATRIC POPULATION: 10 YEARS OF EXPERIENCE

Introducción: Los tumores de las glándulas salivales son infrecuentes en la población en general y comprenden menos del 3% de los tumores de cabeza y cuello1 . En pediatría el 90% corresponden a tumores de la glándula parótida,2 siendo en su mayoría tumores benignos. Objetivo: Describir la incidencia de tumores parotídeos en un centro de referencia, haciendo hincapié en la variabilidad etiológica y la presentación por grupos etarios. Materiales y métodos: Se trata de un estudio de cohorte retrospectivo de pacientes menores de 18 años con tumores de parótida en un periodo de 10 años: de 2011 a 2021, seguidos en el Servicio de Cirugía General Pediátrica del Hospital Italiano de Buenos Aires. Se incluyeron todos los pacientes pediátricos que presentaron tumor en la región parotídea seguidos o tratados en este centro, se excluyeron aquellos que no se pudieron recabar los datos de forma completa. Las variables analizadas fueron edad, sexo, forma de presentación, estudios complementarios, tipo de tratamiento, histología, complicaciones. Resultados: Se analizaron un total de 33 pacientes, de estos un 64% (N = 21) fueron mujeres, con una relación mujer/hombre de 1,7. La media de edad al diagnóstico fue de 8.5 años, siendo 2 de diagnóstico prenatal y hasta los 18 años. La localización fue en un 57% (N = 19) izquierda, el 43% restante derecha. La forma de presentación más frecuente fue la masa palpable en región parotídea 75% (N=25), en dos pacientes fue un hallazgo en estudios por imágenes: resonancia prenatal y otro por resonancia de cerebro. Conclusiones: en pediatría, a diferencia de la población adulta, se presentan una gran variedad de diagnósticos, que incluye desde lesiones vasculares hasta tumores malignos. Debido a que las lesiones parotídeas malignas son clínicamente indistinguibles de las benignas, es importante establecer un diagnóstico preciso. Esta serie representa esta diversidad etiológica en pediatría, así como la distribución etaria comparada con la descrita por la literatura

Introduction: Salivary gland tumors are rare in the general population and comprise less than 3% of head and neck tumors1. In pediatrics, 90% correspond to tumors of the parotid gland,2 being mostly benign tumors. Objective: To describe the incidence of parotid tumors in a reference center, emphasizing the etiological variability and the presentation by age groups. Materials and methods: Tis is a retrospective cohort study of patients under 18 years of age with parotid tumors over a period of 10 years: from 2011 to 2021, followed up at the Pediatric General Surgery Service of the Italian Hospital of Buenos Aires. All pediatric patients who presented tumor in the parotid region followed up or treated in this center were included, those who could not collect the data completely were excluded. Te variables analyzed were age, sex, form of presentation, complementary studies, type of treatment, histology, and complications. Results: A total of 33 patients were analyzed, of which 64% (N = 21) were women, with a female/male ratio of 1.7. Te mean age at diagnosis was 8.5 years, with 2 prenatal diagnoses and up to 18 years. Te location was 57% (N = 19) left, the remaining 43% right. Te most frequent form of presentation was a palpable mass in the parotid region 75% (N=25), in two patients it was a finding in imaging studies: prenatal MRI and another by brain MRI. Conclusions: in pediatrics, unlike the adult population, a wide variety of diagnoses are presented, ranging from vascular lesions to malignant tumors. Because malignant parotid lesions are clinically indistinguishable from benign ones, it is important to establish an accurate diagnosis. Tis series represents this etiological diversity in pediatrics, as well as the age distribution compared to that described in the literature

Surgical treatment strategy in Warthin tumor of the parotid gland / Estratégia de tratamento cirúrgico no tumor de Warthin de glândula parótida

Abstract Introduction: Warthin tumors are the second most common benign tumors of the parotid gland. We examined the clinical features of Warthin tumors in our hospital, and analyzed the consistency within the literatures. Objective: The aim of this study is to analyze the clinical features of Warthin tumors in our 10-year experience of 118 Warthin tumors undergoing surgery at a single institute. Methods: From December 2006 to December 2016, 110 patients who underwent surgical treatment for Warthin tumors were identified based on their medical records. Results: A total of 118 parotid gland operations were performed in 110 patients. Almost 90% of Warthin tumors were found in males, and average patient age was 66.1 ± 6.1 years. The prevalence of smoking history was 89.1% (98/110). Eight patients (7.3%) had bilateral Warthin tumors. Seventy-seven lesions (65.3%) were located in the parotid tail portion, followed by 34 lesions in the superficial lobe (28.8%) and 7 lesions in the deep lobe (5.9%). Conclusion: We determined the appropriate extent of surgery depending on the fine needle aspiration cytology and tumor location by computed tomography scans. Partial facial dysfunction after the operation was detected in 12 cases, and facial nerve function recovered within 3 months. Only one patient experienced a recurrence, and was disease free after the re-operation. We suggest that our treatment algorithm, depending on the location of tumors and the result of fine needle aspiration cytology, can be useful to determine the appropriate extent of surgery for Warthin tumors.

Resumo Introdução: Os tumores de Warthin são os segundos tumores benignos mais comuns da glândula parótida. Avaliamos as características clínicas dos tumores de Warthin em nosso hospital e analisamos a consistência com a literatura. Objetivo: Analisar as características clínicas dos tumores de Warthin em nossa experiência de 10 anos de 118 tumores de Warthin submetidos a tratamento cirúrgico em um único instituto. Método: De dezembro de 2006 a dezembro de 2016, 110 pacientes que receberam tratamento cirúrgico para tumores de Warthin foram identificados com base em seus prontuários médicos. Resultados: Foram feitas 118 cirurgias na glândula parótida em 110 pacientes. Quase 90% dos tumores de Warthin foram encontrados em homens e a média da idade dos pacientes foi de 66,1 ± 6,1 anos. A prevalência de tabagismo foi de 89,1% (98/110). Oito pacientes (7,3%) tinham tumores de Warthin bilaterais na glândula parótida. Das lesões, 77 (65,3%) localizavam-se na porção da cauda da parótida, seguidas por 34 no lobo superficial (28,8%) e 7 no lobo profundo (5,9%). Conclusão: Determinamos a extensão apropriada da cirurgia de acordo com a punção aspirativa com agulha fina e localização do tumor por tomografia computadorizada. Disfunção facial parcial após a cirurgia foi detectada em 12 casos e a função do nervo facial foi recuperada em 3 meses. Apenas um paciente apresentou recidiva e ficou livre da doença após reoperação. Sugerimos que nosso algoritmo de tratamento, a depender da localização dos tumores e do resultado da PAAF, pode ser útil para determinar a extensão apropriada da cirurgia para os tumores de Warthin.
