Siringoma condroide: apresentação incomum de tumor raro / Chondroid syringoma: unusual presentation of a rare tumor

O siringoma condroide, também conhecido como tumor misto cutâneo, é uma neoplasia benigna rara, originada das glândulas sudoríparas, composta por estruturas epiteliais imersas em um estroma mixocondroide. Geralmente, apresenta-se como tumor sólido, único, localizado em face ou pescoço, com evolução crônica e assintomática. Relata-se caso de mulher, 75 anos, com lesão discretamente elevada na fronte, cujo diagnóstico foi definido pela análise histopatológica.

Chondroid syringoma, also known as a cutaneous mixed tumor, is a rare benign neoplasm originating from the sweat glands, composed of epithelial structures immersed in a myxochondroid stroma. It usually presents as a solid, single tumor located on the face or neck with a chronic and asymptomatic course. We report the case of a 75-year-old woman with a slightly elevated lesion on the forehead, whose diagnosis was defined by histopathological analysis.

Clinicopathological and genetic characteristics of bronchial sialadenoma papilliferum: report of four cases / 中华病理学杂志

Objective: To investigate the clinicopathological, immunophenotypic, and molecular genetic features of bronchial sialadenoma papilliferum (BSP). Methods: Four cases of BSP collected at the Shanghai Pulmonary Hospital from May 2018 to June 2021 were retrieved and analyzed. These cases were evaluated for their clinical, histological, immunohistochemical (IHC) and genomic features. The patients were followed up and relevant literature was reviewed. Results: All four patients were male, aged from 55 to 75 years (mean 62 years), with tumor diameter of 6 to 21 mm (mean 13.5 mm), and lesions were located in the left lower lobe (n=2), right lower lobe (n=1), and trachea (n=1). They were characterized by a combination of surface exophytic endobronchial papillary proliferation and an endophytic two-cell layered ductal structure. IHC staining showed that CK7 and EMA were strongly positive in ductal epithelium; p63, p40, CK5/6 were positive in ductal and papillary basal cells; SOX10 was positive in ductal epithelium and basal cells; S-100 was positive in basal cells and ductal epithelium in two cases. Next generation sequencing showed that two cases harbored BRAF V600E mutation. Conclusions: BSP is an extremely rare primary lung tumor arising from the salivary gland under bronchial mucosa. The primary treatment choice of this tumor is complete surgical resection. The diagnosis and differential diagnosis of this tumor depend on classic histomorphologic and IHC features, and BRAF V600E gene mutation can be detected.

Mammary analogue secretory carcinoma in minor salivary gland

ABSTRACT Mammary analogue secretory carcinoma is a rare neoplasm usually confused with other neoplasms in the salivary glands region. It has great similarity with the breast carcinoma. We report a case of a patient who presented with gingival submucosal bleeding and lesion, with the initial histopathological examination revealing salivary gland neoplasm of low crane. Computed tomography revealed the lesion near the tooth 27, with extension to the floor of the left maxillary sinus and to the palate mucosa. Resection of the infra-structure was performed, with a diagnosis of breast cancer secretory carcinoma in the minor salivary gland.

Carcinoma del conducto salival: presentación de un caso / Salivary duct carcinoma: report of a case

El carcinoma de conductos salivales (CCS) es una neoplasia maligna primaria clínica y patológicamente distinta de las glándulas salivales. Debido a su rareza existe una falta de documentación exhaustiva en la literatura con respecto a sus características, manejo y resultados clínicos. En la presente publicación se presenta un caso de un paciente de sexo masculino de 74 años, que acudió al servicio de odontología del Hospital Interzonal General de Agudos Presidente Perón de Avellaneda. El resultado ecográfico arrojó a nivel submaxilar derecho una imagen nodular de aspecto solido que mide 25 x 24 mm Se le realizó la intervención quirúrgica y el resultado anatomopatológico confirmó el diagnóstico de carcinoma de conductos salivales, una de las neoplasias salivales más agresivas. En la actualidad, la muerte ocurre en 60 a 80% de los pacientes, por lo general dentro de los 5 años; alrededor del 33% desarrolla recidiva local y más del 50% metástasis a distancia, en sitios que incluyen pulmones, huesos, hígado, cerebro y piel (AU)

Salivary duct carcinoma (SDC) is a clinically and pathologically distinct primary malignant neoplasm of the salivary glands. Due to its rarity, there is a lack of exhaustive documentation in the literature regarding its characteristics, management, and clinical results. This publication presents a case of a 74-year-old male patient who attended the dentistry service of the Interzonal General Acute Hospital President Perón by Avellaneda. The ultrasound result revealed a nodular image at the right submaxillary level solid aspect measuring 25 x 24 mm. Surgical intervention was performed, and the pathological result confirmed the diagnosis of salivary duct carcinoma, one of the most aggressive salivary neoplasms. Currently, death occurs in 60% to 80% of patients, usually within 5 years; about 33% develop local recurrence and more than 50% distant metastases, at sites including the lungs, bones, liver, brain, and skin (AU)

Pleomorphic Adenoma of the Cheek. Case Report with Review / Adenoma Pleomórfico de Mejilla. Reporte de Caso con Revisión

ABSTRACT: Pleomorphic adenoma (PA), also called benign mixed tumor, is the most common tumor of the salivary glands. About 70 % of these tumors occur in the parotid gland and an uncommon site are the minor salivary glands. The most common sites of PA of the minor salivary glands are the palate followed by lips and cheek. Other rare reported sites include the fauces, floor of the mouth, tongue, tonsil, pharynx, retromolar area and nasal cavity. Here we report a case of pleomorphic adenoma of minor salivary glands of the cheek in a 22-year-old male. The mass was removed by wide local excision with adequate margins, and the patient was followed for 1-year post operatively with no recurrence.

RESUMEN: El adenoma pleomórfico (AP), conocido también como tumor mixto benigno, es el tumor más común de las glándulas salivales. Alrededor del 70 % de estos tumores ocurren en la glándula parótida y con menor frecuencia en las otras glándulas salivales. Los lugares más comunes de AP en las glándulas salivales son el paladar, seguido de labios y mejillas. Otros sitios poco frecuentes reportados, incluyen las fauces, el piso de la boca, la lengua, las tonsilas palatinas, la faringe, el área retromolar y la cavidad nasal. En este estudio se presenta un caso de adenoma pleomórfico de las glándulas salivales menores de la mejilla en un hombre de 22 años. Se extirpó la masa mediante escisión local amplia con márgenes adecuados, con un seguimiento del paciente durante un año después de la operación sin recurrencia.

Unusual treatment of pleomorphic adenoma of soft palate in adult / Tratamiento inusual del adenoma pleomórfico del paladar blando en adulto

Pleomorphic adenoma is the most common benign neoplasia of the salivary glands and affects mostly the parotid gland, less frequently the minor salivary glands. Minor salivary gland tumors have a higher risk of malignancy compared to tumors of the major salivary glands, so appropriate diagnostic evaluation should be prompt. In this case report, we present a case of an extensive pleomorphic adenoma of soft palate in an adult patient. After preoperative investigation using Fine Needle Aspiration (FNA) and imaging tests, the patient was successfully treated by surgical resection under general anesthesia. There was no recurrence seen after a follow-up period of 1 year.

El adenoma pleomórfico es la neoplasia benigna más común de las glándulas salivales y afecta principalmente la glándula parótida, con menos frecuencia en las glándulas salivales menores. Los tumores de las glándulas salivales menores tienen un mayor riesgo de malignidad en comparación con los tumores de las glándulas salivales mayores, por lo que la evaluación diagnóstica apropiada debe ser rápida. En este reporte de caso, presentamos un caso de un extenso adenoma pleomórfico de paladar blando en un paciente adulto. Después de la investigación preoperatoria utilizando aspiración con aguja fina y pruebas de imagen, el paciente fue tratado con éxito con la resección quirúrgica bajo anestesia general. No se observó recurrencia después de un período de seguimiento de 1 año.

RESUMEN Introducción: Los tumores de la glándula submandibular son poco frecuentes. Representan menos del 1% de todos los tumores de cabeza y cuello. Corresponden al 10% de los tumores de las glándulas salivales. Aproximadamente el 50% son malignos. Objetivos: Analizar la experiencia clínica con las submandibulectomias realizadas en el Servicio de Otorrinolaringología y Cirugía de Cabeza y Cuello del Hospital Guillermo Grant Benavente. Material y método: Estudio descriptivo retrospectivo. Revisión de fichas clínicas de pacientes intervenidos de submandibulectomía entre el 01 de enero de 2011 y el 31 de diciembre de 2016 en nuestro servicio. Resultados: Se realizaron 28 submandibulectomías por patología tumoral. La edad promedio fue de 54 años, siendo el 71% de sexo femenino. 21 tumores fueron benignos (75%), siendo el más frecuente el adenoma pleomorfo (14 casos), y 7 tumores malignos (25%), siendo el más frecuente el carcinoma adenoidequístico. Se reportaron dos complicaciones transitorias (7%), una paresia de la rama marginal del nervio facial y una paresia del nervio hipogloso. El 42% de los tumores malignos presentó recurrencia. Conclusión: Nuestra serie presenta resultados acordes a la literatura en cuanto a edad de presentación, distribución por sexo, tipos histológicos, tasa de complicaciones y recurrencia; sin embargo, difiere en la menor frecuencia de tumores malignos, siendo en nuestra serie de 25%. Patología poco frecuente. La presencia de una masa indolora submandibular debe ser derivada a los centros de referencia para estudio y eventual resolución quirúrgica por el riesgo de malignidad.

ABSTRACT Introduction: Submandibular gland tumors are rare. They represent less than 1% of all head and neck tumors. They correspond to 10% of the tumors of the salivary glands. Approximately 50% are malignant. Aim: To analyze the clinical experience with the submandibulectomies performed in the Otorhinolaryngology and Head and Neck Surgery Service of the Guillermo Grant Benavente Hospital. Material and Method: Retrospective descriptive study. Review of clinical records of patients treated with a submandibulectomy between January 1,2011 and December 31, 2016 in our service. Results: 28 submandibulectomies were performed due to tumor pathology. The average age was 54 years, being 71% female. 21 tumors were benign (75%), being the most frequent the pleomorphic adenoma (14 cases), and 7 malignant tumors (25%), being the most frequent the adenoidequistic carcinoma. Two transient complications (7%) were reported, a paresis of the marginal branch of the facial nerve and a paresis of the hypoglossal nerve. 42% of malignant tumors presented recurrence. Conclusion: Our series presents results according to the literature regarding age of presentation, distribution by sex, histological types, complication rate and recurrence; however, it differs in the lower frequency of malignant tumors, being in our series of 25%. Uncommon pathology. The presence of a submandibular painless mass must be referred to the reference centers for study and possible surgical resolution due to the risk of malignancy.

Sensibilidad y especificidad de la punción aspirativa, con aguja fina, de tumores de glándulas salivales mayores en el Hospital Oncológico María Curie / 2 SENSIBILITY AND SPECIFICITY WITH FINE NEEDLE ASPIRATION OF MAJOR SALIVARY GLANDS TUMORS

Los tumores de glándulas salivales son una causa frecuente de consulta en servicios de cabeza y cuello. Para arribar a diagnostico es necesario realizar estudios por imágenes, citológicos a través de la punción aspirativa con aguja fina (PAAF) y anatomía patológica. Objetivo: Evaluar la eficacia de la PAAF en los tumores de glándulas salivales mayores en nuestro medio, teniendo en cuenta los beneficios de ésta y el avance en las técnicas de diagnóstico por imágenes; ¿Estas podrían reemplazar al método citológico? Métodos: Estudio descriptivo y retrospectivo en base a las historias clínicas de los pacientes con tumores de glándulas salivales mayores a quienes se les realizo PAAF, y que posteriormente fueron sometidos a cirugía. Resultados: Se revisaron 113 historias clínicas de pacientes con tumores de glándulas salivales entre Junio de 2010 y Febrero de 2017, se excluyeron 37 (32,7%), quedando incluídos en este estudio 76 pacientes (67,3%). La PAAF hizo diagnóstico en un 84,2% de los pacientes. Sensibilidad del 93% y especificidad del 75%. Conclusión: La PAAF es una prueba sencilla, pero de utilidad limitada en el diagnóstico de tumores de glándulas salivales mayores en nuestro caso debido a la baja especificidad. Es útil para planificar la terapéutica cuando se sospecha la presencia de un tumor maligno, en especial para poder comunicar al paciente y la familia la conducta terapéutica, incluso tomar decisión en pacientes con alto riesgo quirúrgico

Salivary gland tumors are a frequent cause of consultation in head and neck services. In order to arrive at the diagnosis, it is necessary to perform imaging, cytological studies through fine needle aspiration (FNA) and pathological anatomy. Objective: To evaluate the efficacy of FNA in major salivary gland tumors in our setting, taking into account the benefits of FNA and progress in diagnostic imaging techniques; could they replace the cytological method? Methods: Descriptive and retrospective study based on the medical records of patients with tumors of the major salivary glands who underwent FNA and who were subsequently submitted to surgical intra and postperative biopsy. Results: A total of 113 clinical records of patients with salivary gland tumors were reviewed between June 2010 and February 2017, 37 (32.7%) were excluded, and 76 patients (67.3%) were included in the study. The FNA was diagnosed in 84.2% of the patients. Sensibility was 93% and specificity 75%. Conclusion: FNA is a simple test, but of limited utility in the diagnosis of tumors of the major salivary glands in our case due to the low specificity. It is useful to plan the therapeutics when the presence of a malignant tumor is suspected, especially to be able to communicate to the patient and the family the therapeutic behavior, even to make decision in patients with high surgical risk

Uma breve história da cirurgia das glândulas salivares / A brief history of salivary gland surgery

RESUMO As neoplasias das glândulas salivares são relativamente raras, compreendendo cerca de 1% das neoplasias de todo corpo, com incidência de 1/100.000 habitantes por ano. As neoplasias benignas predominam sobre as malignas. O prognóstico depende muito do tipo histológico, grau de diferenciação, localização, infiltração de tecidos vizinhos e da presença de metástases regionais ou a distância. O principal tratamento ainda é a cirurgia, com os seus desafios e dificuldades, devido aos ramos do nervo facial nas glândulas salivares maiores, seguido de radioterapia e em casos selecionados quimioterapia adjuvante. O objetivo desta revisão é fornecer ao leitor uma abordagem histórica sobre o tratamento das doenças das glândulas salivares, com especial atenção às doenças da glândula parótida assim como peculiaridades associadas aqueles que as estudaram ao longo da história.

ABSTRACT Salivary gland neoplasms are a relatively uncommon disease, with nearly one case per 100.000 adults estimated per year and an overall incidence of 1% of all neoplasms. The benign neoplasms are majority and the prognosis depends on the histologic type, grade, localization, soft tissue infiltration, regional and distant metastasis. The main treatment is surgery with caution to facial nerve in the major salivary glands, followed by radiotherapy and chemotherapy in selected cases. The objective of this review is to provide the lector an historic approach about salivary gland diseases treatment, with special attention to the parotid neoplasms and its peculiarities associated to those who studied these glands in their history course.

Remoção cirúrgica de adenoma pleomórfico e uso de placa palatina / Surgical removal of pleomorphic adenoma and use of palatine plaque

O adenoma pleomórfico é a neoplasia, que apresenta maior procedência das glândulas salivares maiores e menores. Clinicamente apresenta-se como lesão solitária, indolor, bem delimitada e de crescimento lento, não se fixando ao tecido adjacente. O tratamento de eleição consiste na excisão cirúrgica da lesão, com pequena margem de segurança. Este trabalho tem como objetivo relatar um caso de adenoma pleomórfico, localizado no palato com quatro anos de evolução de uma pacíente do gênero feminino, faioderma, na quarta década de vida. Inicialmente realizou-se biópsia incisional para ratificação histopatológica da hipótese diagnóstica inicial. No segundo tempo cirúrgico, realizou-se enucleação da lesão e instalação da placa palatina no pós-operatório imediato, melhorando substancialmente o conforto do paciente e a cicatrização da ferida cirúrgica. Após um ano de acompanhamento, não existem evidências clínicas de recidiva tumoral... (AU)

The pleomorphic adenoma is the neoplasm with the highest incidence of major and minor salivary glands. Clinically presents as a solitary lesion, painless, well outlined and slow growth, not fixing to adjacent tissue. The treatment of choice is surgical excision of the lesion with a small margin of safety. This study aims to report a case of pleomorphic adenoma found on the palate with four years of the evolution of a female patient, brunette skin, in the fourth decade of life. Initially held incisional biopsy for histopathological confirmation of the diagnosis. In the second procedure was performed enucleation of the lesion and installation of the palatal plate in the immediate postoperative period, substantially improving patient comfort and healing of the surgical wound.

Resección transoral-transnasal de tumores del espacio parafaríngeo / Transoral-transnasal approach to parapharyngeal space tumors

Objetivos: Determinar la tasa de resección quirúrgica completa en tumores seleccionados del Espacio parafaríngeo tratados por vía transoral o transnasal o por ambas. Diseño: descriptivo, retrospectivo. Materiales y métodos: Se incluyeron en este estudio los pacientes que tuvieron neoplasias localizadas en el espacio parafaríngeo y que fueron tratados con cirugía por vía transoral o transnasal. El abordaje transoral consistió en realizar una incisión con cauterio en la zona de mayor protrusión del tumor (pilar amigdalino y paladar), disección de la mucosa y del tumor de los planos profundos, traccionándolo hacia la cavidad oral. Para disecar el límite superior (rinofaringe) y lateral se utilizaron endoscopios que fueron introducidos por la incisión y por la cavidad nasal. El abordaje transnasal consistió en realizar una incisión en la pared lateral de la rinofaringe y disecar el tumor del plano profundo traccionándolo hacia el cavum. Resultados: Fueron tratados 3 pacientes por vía transoral y uno por vía endonasal por padecer tumores del espacio parafaríngeo. Tres tumores se originaron en glándulas salivales menores localizadas una en el espacio. Preestiloideo (1/3), otra en el espacio masticador (1/3) y otra en el sector superior del espacio preestiloideo (1/3). La histología dio como resultado dos adenoma pleomorfo y un carcinoma mucoepidermoide de bajo grado (1/3). (Está bien así? Qué es 1/3?). Una neoplasia se originó en el lóbulo profundo de la parótida y se extendió al espacio preestiloideo, su histología fue carcinoma mucoepidermoide de grado moderado. Conclusiones: La tasa de resección completa en pacientes con tumores del espacio parafaríngeo seleccionados tratados por vía transoral y endonasal fue del 100%. (AU)

Objectives: To determine the rate of complete surgical resection in parapharyngeal space selected tumors treated with transoral and / or transnasal approach. Design: Descriptive, retrospective. Materials and methods: Patients who had tumors localized in parapharyngealspace and who were treated with transoral or transnasal surgery. were included in this study. The transoral approach consisted in performing an incision with cautery in the area of greates tumor protrusion (tonsillar pillar and palate), dissection of the mucosa and tumor of the deep planes, pulling it into the oral cavity. To dissect the upper limit (nasopharynx) and lateral we used endoscopes that were inserted by the incision and the nasal cavity. The transnasal approach consisted in making an incision in the side wall of the nasopharynx and dissect the tumor of the deep plane pulling it towards the cavum. Results: Three patients were treated with transoral and one byendonasalapproacheswho had parapharyngeal space tumors. Three tumors originated in minor salivary glands located in prestyloidspace (1/3), masticator space (1/3) and upper sector of pree-styloid space (1/3). Histology was in two pleomorphic adenoma, and another onelow degree mucoepidermoid carcinoma (1/3). A neoplasm was originated in the deep lobe of the parotid gland and was extended to the prestyloid space, was a moderate degree of mucoepidermoid carcinoma. Conclusions: Complete resection rate in patients with selected parapharyngeal space tumors, treated by transorally and endonasal approach was 100%. (AU)

Study of Salivary Gland Neoplasms.

Tumors of the salivary glands are uncommon and they present a great variety of histological types with many structural variation. They have a low incidence and their anatomical relationship especially that of the parotid gland to the facial nerve make their management challenging. The present study was carried out to find out the prevalence of salivary gland neoplasms, to see associated conditions like sialadenitis, sialolithiasis coexisting with salivary gland neoplasms and to do cytohistopathological correlation. Total 96 cases were collected of which 66.7% were benign and 33.3% were malignant. In 81 (84.3%) cases tumors occurred in major salivary gland while 15 (15.6%) cases in minor salivary gland. Among major salivary gland, parotid was the commonest site and in minor salivary glands, palate was the commonest site followed by lips. Pleomorphic adenoma was the commonest benign tumor and adenoid cystic carcinoma was the commonest malignant tumor followed by mucoepidermoid tumor. There was one case of synovial sarcoma. Associated pathology like sialadenitis and sialolithiasis were present in 16 benign and 5 malignant tumors. Cytohistocorrelation was seen in 63 out of 64 (98.4%) benign and 16 out of 18 (88.8%) malignant tumors.

Pleomorphic adenoma of the palate: two cases report and literature review / Adenoma pleomorfo palatino: reporte de 2 casos y revisión de la literatura

Pleomorphic adenoma (PA) is the most common neoplasm encountered in major and minor salivary glands. Intraorally, it is most frequently developed in the palatal glands. Histologically, it is characterized by a diverse architecture comprised of epithelial stromal elements mixed with mucoid, myxoid, or chondroid fibrohyaline. A PA does not generally present gender bias and can occur at any age with the same clinical behavior. It is usually a round, slow-growing, painless tumor, which is firm upon palpation. We reported two cases of adult patients who were treated using transoral resection at San Juan de Dios Hospital in La Serena.

El Adenoma Pleomorfo es la neoplasia más común de las glándulas salivales mayores y menores. Intraoralmente las glándulas del paladar son las más afectadas. Histológicamente se caracteriza por una arquitectura variada que comprende elementos epiteliales mezclados con estroma mucoide, mixoide, fibrohialino o condroide, Los AP no suelen presentar predisposición por sexos, pudiendo aparecer a cualquier edad, con el mismo comportamiento clínico. Se presentan habitualmente como una tumoración redondeada de crecimiento lento, indolora y firme a la palpación. Presentamos dos casos de pacientes adultos, quienes fueron tratados mediante resección transoral en el hospital de la Serena.

Adenoma pleomorfo palatino: presentación de escisión alterna con descenso de colgajo palatino de espesor total / Pleomorphic adenoma of the palate: presentation of a surgical excision technique involving the elevation of a full-thickness palatal flap

El adenoma pleomorfo es la neoplasia benigna de glándulas salivales más común, tanto de glándulas mayores como de menores. La localización intraoral más frecuente es entre los límites del paladar duro y paladar blando y puede llegar a impedir una adecuada masticación, fonación, así como a disminuir el libre paso de alimentos. La recurrencia de dichas lesiones es alta si no llevamos a cabo una técnica quirúrgica adecuada, tanto para remover la lesión en su totalidad como para respetar la cápsula que la rodea. En el presente artículo, se presenta un caso clínico realizado en el Hospital Juárez de México, de una paciente con lesión de adenoma pleomorfo palatino de tamaño considerable, en donde se realizó la escisión quirúrgica de manera alterna con un descenso de colgajo palatino de espesor total y remoción completa de la lesión, conservando en todo momento su cápsula. En el seguimiento a largo plazo no se observaron recurrencias, neoformaciones, y encontramos una adecuada remodelación y adaptación del colgajo en su posición original.

Pleomorphic adenoma is the most common benign neoplasm of both the major and minor salivary glands. The most frequently intraoral location is between the boundaries of the soft and hard palates. It can impede proper mastication and phonation, and prevent food from passing freely. The recurrence rate for this kind of lesion is high if a suitable surgical technique is not used, in terms of both removing the entire lesion and ensuring that the capsule that surrounds it is not compromised. In this article, we present a clinical case study carried out at the Juarez Hospital, involving a female patient with a large pleomorphic adenoma lesion. We performed an alternative surgical excision involving the elevation of a full-thickness palatal flap and complete removal of the lesion, whilst preserving its capsule. In the long-term follow up, no recurrences or neoformations were observed and we found an adequate remodeling and adaptation of the flap into its original position.

Los cistoadenocarcinomas son neoplasias raras recientemente incluidas en la nueva clasificaciónde tumores de glándulas salivales de la Organización Mundial de la Salud (OMS), como un tipo específico de carcinoma diferenciado histomorfológicamente por exhibir un patrón quístico y un crecimiento papilar y carecer de otras características histológicas presentes en otras formas de carcinomas de glándulas salivales que pueden formar estructuras quísticas. Los autores presentamos un caso clínico quirúrgico de un cistoadenocarcinoma de glándula salival ectópica y la revisión bibliográfica correspondiente.

Lesiones intraorales de glándulas salivales menores / Intraoral lesions of minor salivary glands: analysis of 59 patients

Background: Most salivary gland lesions are benign. Tumors are uncommon. Pleomorphic adenoma and cystic adenoid carcinoma are the most common benign and malignant lesions. Aim: To assess the incidence management and evolution of intraoral lesions among patients consulting in a head and neck surgical service. Material and Methods: Retrospective review of medical records of patients consulting for intraoral lesions of minor salivary glands between 1975 and 2009 in a head and neck surgical service. Results: Thirty five females and 24 males are reported. Forty eight (81 percent) had benign lesions. Of these, 35 (73 percent). were non neoplastic lesions. Eleven patients had malignant lesions. Of these, four (36 percent) had a mucoepidermoid carcinoma, two (18 percent) had an adenoid-cystic carcinoma, two (18 percent) had an acinous cell carcinoma and one patient each had an undifferentiated carcinoma, an adenocarcinoma and an epidermoid carcinoma. Conclusions: In this series of patients, benign lesions predominated. Benign lesions were excised and the management of malignant lesions depended on the type of tumor.

Introducción: Las lesiones de glándulas salivales menores son en su mayoría benignas. Los tumores son infrecuentes y conforman un grupo heterogéneo, siendo el adenoma pleomorfo la neoplasia benigna más frecuente y el carcinoma adenoideo-quístico el tumor maligno más encontrado. Objetivos: El propósito de este estudio es evaluar la incidencia, manejo y evolución de las lesiones intraorales de glándulas salivales menores en el Servicio de Cirugía de Cabeza y Cuello del Hospital Barros Luco-Trudeau. Material y Método: Se presenta estudio retrospectivo de 59 casos tratados entre 1975 y 2009 en dicho hospital. Resultados: Encontramos 35 mujeres y 24 hombres. En 48 pacientes (81,3 por ciento) se encontró lesiones benignas, de las cuales 35 (73 por ciento) correspondieron a lesiones no neoplásicas y 13 (27 por ciento) a neoplasias. Las neoplasias malignas fueron 11 (18,6 por ciento del total), 4 (36,3 por ciento) con Ca mucoepidermoide, 2 (18 por ciento) con Ca adenoideo-quístico, 2 (18 por ciento) con Ca de células acinosas, 1 (9 por ciento) con Ca indiferenciado, 1 (9 por ciento) con adenocarcinoma y 1 (9 por ciento) con Ca epidermoide. Conclusiones: Las lesiones de glándulas salivales menores en nuestro hospital se caracterizan por ser predominantemente benignas. Se encontró similar frecuencia de tumores benignos y malignos. Predominó el adenoma pleomorfo entre los primeros y el carcinoma mucoepidermoide entre los segundos. Los tumores benignos, luego de su extirpación, se manejaron con cierre del lecho tumoral mediante rotación de colgajos locales de mucosa oral para cobertura y, en algunos casos, cierre por segunda intención. La evolución fue en general excelente. En el caso de los tumores malignos, el manejo dependió de Ia histología.

Adenoma pleomorfo del septum nasal, dos casos clínicos y revisión del tema / Pleomorphic adenoma of the nasal septum: two clinical cases

El tumor benigno más frecuente de las glándulas salivales mayores es el adenoma pleomorfo. Además de las glándulas salivales mayores, también puede ocurrir en las glándulas salivales del paladar duro y blando. Raros casos se han reportado en la nasofaringe, orofaringe, hipofaringe y laringe. Adenomas pleomorfos intranasales son muy infrecuentes y pueden ser mal diagnosticados debido a que tienen mayor celularidad mioepitelial y poco estroma mixoide, en comparación con los que se localizan en otros lugares. Presentamos dos raros casos de adenomas pleomorfos del septum nasal y analizamos los hallazgos patológicos y el manejo clínico. Se revisa la literatura en relación al tema.

The most common benign tumor of major salivary glands is the pleomorphic adenoma. In addition to the major salivary glands may also occur in the salivary glands of hard and soft palate. Rare cases have been reported in the nasopharynx, oropharynx, hypopharynx and larynx. Intranasal pleomorphic adenomas are very rare and can be misdiagnosed because they have greater myoepithelial cellularity and little myxoid stroma, compared with those located elsewhere. We report two rare cases of pleomorphic adenomas of the nasal septum and analyze the pathological findings and clinical management. We review the literature on the subject.
