ABSTRACT

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.

ABSTRACT

Introdução: As neoplasias de glândulas salivares constituem um grupo de lesões, clínica e morfologicamente diferente, capaz de determinar importantes desafios diagnósticos e terapêuticos. Apresentar dois casos de tumores benignos de glândulas salivares menores, sendo um adenoma e outro mioepitelioma, discutindo o diagnóstico diferencial e a forma de tratamento em comparação com informações da literatura. Relato de caso: Pacientes do sexo feminino, com idades semelhantes, ambas se queixavam que após o uso de uma prótese mal adaptada notou-se o aparecimento de uma lesão assintomática no palato. Diante das características clínicas das lesões, as hipóteses de diagnóstico foram de tumor de glândula salivar menor e adenoma pleomórfico, respectivamente. Diante da ausência de sinais de malignidade, o tratamento proposto foi biópsia excisional com enucleação e curetagem. O diagnóstico histopatológico foi de Tumor de Glândula Salivar Menor (Mioepitelioma Plasmocitóide), e Adenoma Pleomórfico, respectivamente. A enucleação e curetagem se mostraram eficazes e sem sinais de recidiva. Considerações finais: Tanto o adenoma como o mioepitelioma se apresentam clinicamente semelhantes sendo o diagnóstico diferencial realizado através do histopatológico, porém o tratamento conservador de enucleação e curetagem pode ser aplicado em ambas...

Introduction: The neoplasms of salivary gland constitute a group of lesions clinically and morphologically different, which are able to determine important challenges in diagnostic and therapeutic.To report two cases of benign tumors of the minor salivary glands, adenoma and myoepithelioma. Also, discussing the differential diagnosis and its treatment in comparison with literature information. Case report: Two female patients, with similar ages, both complained about the appearance of an asymptomatic lesion on the palate after using a poorly adapted prosthesis. On the clinical characteristics of the lesions, the hypothetical diagnosis was of minor salivary gland tumor and pleomorphic adenoma, respectively. In the absence of signs of malignancy, the proposed treatment was excisional biopsy with enucleation and curettage. The histopathology diagnosis was begin tumor of minor salivary glands (myoepithelioma plasmacytoid), and pleomorphic adenoma, respectively. The enucleation and curettage were effective and there were no signs of recurrence. Final considerations: Both the adenoma and myoepithelioma are clinically similar and the differential diagnosis is performed by the histopathology exam, but conservative treatment such as enucleation and curettage can be applied to both...

ABSTRACT

RESUMEN El adenoma pleomorfo constituye la neoplasia benigna más frecuente de las glándulas salivales mayores, y puede también presentarse en otros sitios con mucha menor frecuencia como orofaringe, hipofaringe y nasofaringe. El adenoma pleomorfo intranasal es muy infrecuente y los casos descritos en la literatura local se refieren a tumores septales. Se presenta un caso clínico de una paciente que consulta por obstrucción nasal unilateral a derecha asociado a, epistaxis y epífora ipsilateral con estudio imagenológico y biopsia que sugiere adenoma pleomorfo de la pared lateral nasal. Se realiza revisión bibliográfica al respecto.


ABSTRACT The pleomorphic adenoma is the most frequent benign neoplasm of the major salivary glands. It can also present itself in other places with much less frequency such as oropharynx, hypopharynx and nasopharynx. The intranasal pleomorphic adenoma is very unusual and the cases described in the local literature address septal tumors. A clinical case is presented of a patient who consulted for unilateral right nasal obstruction associated with epistaxis and ipsilateral epiphora with imaging study and biopsy suggesting pleomorphic adenoma of the lateral nasal wall. A bibliographic review is made in this regard.

ABSTRACT

Pleomorphic adenoma is the most common benign neoplasm of salivary glands. Their common location is in parotid gland, however, a lower percentage of these tumors might occur in minor glands. The epidemiology of this tumor shows that adults are the most affected, with rare occurrence in children or adolescents. We present the case report of pleomorphic adenoma located on the palate of a 10 year old. Excisional biopsy of the lesion followed by histopathologic examination of the biopsy specimen revealed ductal structures surrounded by plasmacytoid mioepithelial cells within a myxoid stroma, the final diagnosis corresponded to Pleomorphic Adenoma. Early detection and excision of this lesion in children are important to minimize potential recurrences or malignant transformation.


El adenoma pleomorfo es la neoplasia benigna más común de las glándulas salivales. Su localización común está en glándula parótida, sin embargo, un bajo porcentaje de estos tumores puede ocurrir en glándulas menores. La epidemiología de este tumor muestra que los adultos son los más afectados, con rara ocurrencia en niños o adolescentes. Presentamos el caso de un adenoma pleomorfo localizado en el paladar de un niño de 10 años. La biopsia excisional de la lesión seguida de examen histopatológico de la muestra de biopsia reveló estructuras ductales rodeadas por células mioepiteliales plasmocitóides dentro de un estroma mixoide, siendo el diagnóstico final adenoma pleomorfo. La detección temprana y la excisión de esta lesión en los niños es importante para minimizar las recidivas potenciales o la transformación maligna.

ABSTRACT

El adenoma pleomorfo es el tumor benigno más frecuente de las glándulas salivales, con mayor predilección por la glándula parótida. Se presenta un caso clínico de paciente femenino de 53 años de edad, con aumento de volumen en región parotídea y geniana derecha de15 × 12 centímetros, de ocho años de evolución, la tomografía simple de la región presenta tumoración parotídea bien delimitada, la cual afecta lóbulo superficial y profundo de la glándula parótida derecha, la biopsia incisional confi rmó el diagnóstico histopatológico de adenoma pleomorfo por lo cual se realiza parotidectomía total sin preservación del nervio facial.


Pleomorphic adenoma is the most common benign tumor of the salivaryglands, with greater predilection for the parotid gland. We presentthe case of a 53-year-old female patient with a 15 x 12 cm increasein volume in the parotid and right genial region with eight years ofevolution. A simple CT scan of the region revealed a well-defi ned parotidtumor aff ecting the superfi cial and deep lobe of the right parotidgland. An incisional biopsy confi rmed the histopathological diagnosisof pleomorphic adenoma, for which reason a total parotidectomy wasperformed without preservation of the facial nerve.

ABSTRACT

Introducción: El Siringoma Condroide o tumor mixto es una neoplasia habitualmente benigna que constituye 0,01 por ciento de los tumores primarios de la piel. Es una entidad análoga al tumor mixto (Adenoma Pleomorfo) de glándulas salivales. El diagnóstico es exclusivamente histopatológico. Objetivo: Presentar una paciente con un diagnóstico poco común de Siringoma Condroide benigno, donde se destaca como diagnóstico diferencial entre los tumores de la piel en cabeza y cuello. Presentación de caso: Presentamos el caso de una paciente femenina, de 45 años de edad, quien acude a consulta por presentar un nódulo subcutáneo en la región geniana derecha, que apareció como un pequeño aumento de volumen debajo de la piel, que fue creciendo gradualmente, asintomático, redondeado, bien delimitado, móvil, de consistencia entre suave y firme, de varios meses de evolución, como única lesión. Clínicamente se interpretó como un quiste epidérmico. Su diagnóstico anatomopatológico fue el de Siringoma Condroide benigno o Tumor mixto de la piel. Conclusiones: Resulta un caso interesante debido a la baja frecuencia de presentación de esta lesión. Es importante tener presente esta entidad en el diagnóstico diferencial de los tumores de la piel en cabeza y cuello. A pesar de ser un tumor benigno es necesario el seguimiento del paciente, pues, aunque es muy raro, se han descrito casos con un comportamiento maligno(AU)


Introduction: Chondroid syringoma or mixed tumour is usually a benign neoplasia, constituting 0.01 percent of primary tumours of the skin. This is analogous to mixed tumour (Pleomorphic adenoma) of salivary gland. The diagnosis is only histopathologically. Objective: To present a patient with a diagnosis not very common of chondroid syringoma, where it is highlighted as differential diagnosis among the head and neck skin tumours. Case presentation: Is presented a case of a female patient; 45 years old, that arrived to the consulting room showing a subcutaneous nodule on the right genial region, it appeared as an asymptomatic slow-growing small mass, rounded, well bounded, mobile of soft and firm consistence, of several months of evolution, as a single lesion. The diagnosis was a chondroid syringoma or skin mixed tumour. Conclusions: It is an interesting case because it has a low frequency. It is important bear in mind this entity in the differential diagnosis of head and neck skin tumours. Despite being a benign tumour it is necessary to monitor patients, because even though it is uncommon, some cases have been reported with a malignant behaviour(AU)

ABSTRACT

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)

ABSTRACT

Paciente masculino de 81 años de edad que acudió a consulta con un cirujano dentista por presentar una lesión nodular, asintomática, firme y móvil en el labio superior del lado derecho. El sujeto refi rió tener la lesión desde la infancia, pero notó crecimiento lento en el último año. El diagnóstico clínico indicaba un adenoma pleomorfo, por lo que el individuo se sometió a biopsia escisional bajo anestesia local. El espécimen se envió a estudio histopatológico. La evolución del paciente fue satisfactoria, sin reincidencia de la lesión. El examen microscópico reveló la presencia de una neoplasia bien delimitada constituida pormúltiples estructuras ductales pequeñas en la dermis. Estos ductos se encontraban revestidos por dos hileras de células epiteliales planas y contenían cantidades variables de material amorfo en la luz. El estroma presentaba diferenciación condroide.


An 81-year-old male patient consulted a dental surgeon due to his presenting a fi rm, mobile, asymptomatic nodular lesion on the upper lip. The patient stated that he had had the mass since childhood but that it had grown slowly over the course of the previous year. The clinical diagnosis was pleomorphic adenoma, for which reason the patient underwent an excisional biopsy under local anesthesia. The specimen was sent for histopathological examination. The patient’s progress was satisfactory and there was no recurrence of the lesion. Micro-scopic examination revealed the presence of a well-defi ned neoplasm consisting of multiple small ductal structures located in the dermis. These ducts were lined with two rows of fl attened epithelial cells and contained varying amounts of amorphous material in the lumen. The stroma exhibited chondroid differentiation.

ABSTRACT

INTRODUCTION: Benign tumors of the parotid gland comprise the majority of salivary gland tumors. OBJECTIVE: To review the clinical characteristics of parotid gland tumors submitted to surgical treatment by the same surgeon. METHODS: Retrospective study with 154 patients who had parotid gland tumors. Clinical and histological data, type of surgery, and complications were assessed and described. RESULTS: The main manifestation was a mass with a median evolution of 12 months for benign tumors and five months for malignant tumors. Ultrasonography was the most frequent complementary exam. Pleomorphic adenoma was the most common of the benign tumors, and mucoepidermoid carcinoma was the most frequent malignant tumor. Superficial parotidectomy with preservation of the facial nerve was the most common surgical procedure and reversible paresis of branches of the facial nerve was the most common complication. CONCLUSIONS: Pleomorphic adenoma is the most common parotid gland tumor and superficial parotidectomy with preservation of the facial nerve is the most common and appropriate treatment for most low-morbidity tumors. .


INTRODUÇÃO: Os tumores de parótida são frequentemente de natureza benigna e correspondem à maioria dos tumores de glândulas salivares. OBJETIVO: Revisar as características clínicas de neoplasias de parótidas submetidas a tratamento cirúrgico pelo mesmo cirurgião. MÉTODO: Estudo retrospectivo, onde foram avaliados 154 pacientes com neoplasia de parótida. Dados clínicos, histológicos, tipo de cirurgia e complicações foram compilados e descritos. RESULTADOS: A principal manifestação foi a de uma massa tumoral com uma mediana de tempo de evolução de 12 meses para os tumores benignos e 5 meses para os tumores malignos. A ecografia foi o exame complementar mais indicado. Dentre os tumores benignos, o adenoma pleomórfico foi o mais comum e o carcinoma mucoepidermóide o mais frequente dentre os malignos. A parotidectomia superficial com preservação do nervo facial foi a cirurgia mais indicada e a paresia reversível de ramos do nervo facial, a complicação mais prevalente. Conclusões: O adenoma pleomórfico é o tumor mais comum da glândula parótida e a parotidectomia superficial com preservação do nervo facial é o tratamento mais adequado para a maioria dos tumores de baixa morbidade. .

ABSTRACT

Pleomorphic adenoma is a benign mixed tumor, which is composed of myoepithelial and epithelial cells. A fibrous capsule separates these cells from the surrounding tissues. Pleomorphic adenoma has unusual histopathologic features. It is the most common benign tumor affecting both major and minor salivary glands. Parotid salivary gland is affected mostly in the major group, and palate is the most common site affected in minor salivary glands. The upper lip is the second most common site followed by buccal mucosa. Less than 3% of the salivary gland tumors account for head and neck tumors. In few cases, benign pleomorphic adenoma may turn malignant also. In this case report, a female patient aged 32 years who reported with a complaint of painless swelling in the palate is presented.

ABSTRACT

O presente estudo teve como objetivo analisar o adenoma pleomórfico (AP) em sua integralidade, buscando expor ao cirurgião-dentista os melhores métodos de diagnóstico e tratamento. Revisão de literatura: o AP é a mais comum neoplasia benigna de glândulas salivares. Acredita-se que o AP seja derivado de uma mistura de elementos ductais e mioepiteliais. Apresenta predileção pelo sexo feminino e pela faixa etária dos 30 aos 60 anos. Localiza-se mais comumente nas glândulas parótidas, seguidas das submandibulares e salivares menores. Apresenta como manifestação clínica um aumento de volume firme, indolor e de crescimento lento. Os métodos de diagnóstico auxiliares são: sialografia, ultrassonografia, tomografia computadorizada, ressonância magnética, mas o diagnóstico definitivode AP é dado pela realização do exame histopatológico. O tratamento para a lesão consiste na sua exérese, por vezes, com parte da glândula afetada. O prognóstico da lesão é favorável, porém apresenta uma complicação potencial que é o risco de malignização. Relato de caso: no presente estudo relatou-se um caso de AP em paciente leucoderma, feminino, 36 anos de idade, apresentando tumefação firme, assintomática de superfície lisa, no lado direito do palato duro, medindo aproximadamente 3 cm. Foi realizada biópsia incisional do caso e o exame histopatológico confirmou o diagnóstico de AP. Devido à extensão da lesão, a paciente foi encaminhada para realizar a remoção cirúrgica com cirurgião de cabeça e pescoço. Conclusão: apesar de relativamente comum, o AP pode atingir grandes dimensões, devendo o cirurgião-dentista realizar seu diagnóstico e realizar o correto encaminhamento para profissional da área médica...


This study aimed to analyze the pleomorphic adenoma (PA) in its entirety, seeking to expose the dentist the best methods of diagnosis and treatment. Literature review: the PA is the most common benign tumor salivary glands. It is believed that the PA is derived from a mixture of myoepithelial and ductal elements. It is more prevalence among females and in the age group 30 to 60 years. It located most commonly in the parotid, followed by the submandibular and then the small glands. The clinical manifestation is a localized increase of size, firm, painless and of slow growth. Auxiliary diagnostic methods are: sialography, ultrasonography, computed tomography, magnetic resonance, but the definitive diagnosis of PA is given by the completion of the histopathological examination. Excision is the treatment for the lesion sometimes including part of the affected gland. The prognosis of the injury is favorable, but it presents a potential complication that is the risk of malignancy. Case report: it is reported a case of PA in a Caucasian patient, female, 36 years old, with firm swelling, asymptomatic, smooth surface on the right side of the hard palate, measuring approximately 3 cm. Incisional biopsy was held and histopathological examination confirmed the diagnosis of PA. Due to the extent of the injury, the patient was referred for surgical removal with head and neck surgeon. Conclusion: although relatively common, the PA can reach large size. Therefore, the dentist should confirm the diagnosis and correctly referrer the case to surgical treatment...

ABSTRACT

Existe una gran controversia acerca de la extensión del margen requerido para la remoción del adenoma pleomorfo en la glándula parótida. Si bien el tratamiento del adenoma pleomorfo más aceptado mundialmente es la parotidectomía superficial con disección del nervio facial, en la literatura se describe un amplio espectro de tratamientos, que van desde parotidectomía total hasta la disección extracapsular. La disección extracapsular consiste en la disección del tumor por fuera de la cápsula, sin la necesidad de un margen amplio ni de la identificación previa del nervio facial. El objetivo de este trabajo es presentar las ventajas, desventajas, indicaciones y limitaciones de la disección extracapsular para la remoción del adenoma pleomorfo de la glándula parótida.

ABSTRACT

El adenoma pleomorfo es el tumor benigno más frecuente de lasglándulas salivales. Su localización principalmente es en la glándula parótida, pero cuando aparece en una glándula salival menor, el paladar es su localización más común. Presenta un crecimiento lento y continuo; clínicamente se presenta como un nódulo o tumor asintomático, firme y bien delimitado. El diagnóstico se realiza mediante biopsia por aspiración con aguja fi na o biopsia escisional de la lesión, siendo de gran importancia debido a que a pesar de ser una tumoración benigna, en ocasiones puede presentar transformación maligna. El tratamiento consiste en la exéresis completa de la lesión con márgenes sanos. Se presenta el caso de un paciente masculino de 40 años, con una masa en el paladar duro y blando de seis años de evolución. Tras la exéresiscompleta de la lesión, el estudio histopatológico confirmó el diagnósticode adenoma pleomorfo


Pleomorphic adenomas are the most common benign tumor of the minor salivary glands. They are primarily found in the parotid gland, except when they appear in a minor salivary gland, in which case the palate is the most common site. They display a slow, steady growth. Clinically the adenoma appears as a fi rm, well-defi ned, asymptomatic nodule or tumor. Diagnosis is confi rmed by means of fi ne-needle aspiration biopsy or excisional biopsy of the lesion. It is extremely important that they are tested given that, despite their being a benign tumor, they can sometimes become malignant. Treatment consists of the complete excision of the lesion with clean surgical margins. We report the case of a 40-year-old male patient with a mass in the hard and soft palate that had evolved over a period of six years. Following the complete excision of the le-sion, histopathology confi rmed the diagnosis of pleomorphic adenoma.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Pleomorphic adenoma (PA) is the most common tumor of the salivary glands. About 90% of these tumors occur in the parotid gland and 10% in the minor salivary glands. The most common sites of PA of the minor salivary glands are the palate, followed by lips and cheeks. Throat, floor of the mouth, tongue, tonsil, pharynx, retromolar area and nasal cavity are rarely involved. Here, we report a case of PA of the cheek in a 42-year-old female. The mass was excised and the patient was followed for 3 years post operatively with no recurrence.
