ABSTRACT

El carcinoma mucoepidermoide es el tumor maligno más frecuente de las glándulas salivales menores localizándose por lo general en el paladar. El objetivo del presente reporte de caso es evidenciar en la literatura científica la importancia del diagnóstico precoz de carcinomas orales, así como, el rol fundamental que cumple el odontólogo general para identificar, guiar y derivar al paciente a un especialista. Se presenta el caso clínico de un paciente de sexo masculino que acudió a la Facultad de Odontología de la Universidad Nacional de Asunción, quien fue derivado por su odontóloga tras percibir un pequeño pero perceptible cambio en la coloración normal de la mucosa y molestias ocasionales en la zona del paladar duro. Al examen intraoral se observó en el paladar duro, a la altura de los premolares en la hemiarcada izquierda, una lesión nodular ovoidea, color violáceo, de 1cm de diámetro, depresible a la palpación. Se realizó una biopsia incisional para su estudio histopatológico, reportando un carcinoma mucoepidermoide. El diagnóstico precoz de este tipo de patologías es un desafío para el odontólogo general, quien debe orientar al paciente, ante cualquier cambio de la estructura normal de la cavidad bucal, para que acuda a un especialista.


Mucoepidermoid carcinoma is the most frequent malignant tumor of the minor salivary glands, usually located in the palate. The objective of this case report is to demonstrate in the Paraguayan scientific literature the importance of early diagnosis of oral carcinomas as well as the fundamental role of the general dentist in identifying, guiding and referring the patient to the corresponding specialist. The clinical case presented is about a male patient who attended the Faculty of Dentistry of the National University of Asuncion. His dentist referred him after noticing a small but perceptible change in the normal coloration of the mucosa and occasional discomfort in the area of the hard palate. In the intraoral examination, an ovoid nodular lesion, purplish in color, 1cm in diameter, depressible on palpation, observed on the hard palate at the level of the premolars in the left hemiarch. An incisional biopsy performed for histopathological study, reporting a mucoepidermoid carcinoma. Regarding the early diagnosis of this type of pathology, the challenge for the general dentist will continues to be his continuous training in order to be able to successfully guide the patient in seeking care from the right specialist in case of any change in the oral cavity.

ABSTRACT

Solitary fibrous tumor (SFT) is a neoplasm of fibroblastic/myofibroblastic origin with intermediate biological behavior. We report here two cases of SFT affecting an unusual anatomical site in 58-year-old and 40-year-old female patients and discuss the differential diagnosis of this lesion. In case 01, the lesion showed the clinical appearance of an asymptomatic "blister" with normal color, rubbery consistency, measuring 0.3 cm, and affected the lower lip; while in case 02, a symptomatic red nodular lesion with a soft consistency and measuring 0.5 cm affected the floor of the mouth. Excisional biopsies were performed. Microscopically, two well-delimited benign neoplasms were observed, exhibiting the proliferation of ovoid to spindle-shaped mesenchymal cells, vascular spaces with staghorn arrangement, and the absence of mitosis figures. Immunohistochemistry was performed in case 01 to assist in the diagnosis. Weak and diffuse immunostaining was observed for α-SMA and intense and diffuse immunopositivity for Bcl-2 and CD34. Based on histopathological and immunohistochemical features, a diagnosis of SFT was rendered in both cases. The low occurrence and nonspecific clinical features of oral SFT may make its clinical diagnosis difficult. Also, morphological and immunohistochemical are essential for differential diagnosis with other mesenchymal neoplasms.(AU)


O tumor fibroso solitário (TFS) é uma neoplasia de origem fibroblástica/miofibroblastica com comportamento biológico intermediário. Nesse artigo relatamos dois casos de TFS afetando sítios anatômicos incomuns em pacientes do sexo feminino de 58 anos e 40 anos e discutir os seus diagnósticos. No caso 01 clinicamente a lesão apresentou um aspecto de "bolha" assintomática, coloração normal da mucosa, consistência borrachoide medindo 0,3 cm, em região de lábio inferior, enquanto que no caso 02, como uma lesão sintomática, vermelha, nodular com consistência mole e medindo 0,5 cm afetando o assoalho bucal. As biópsias excecionais foram realizadas. Microscopicamente, observamos duas lesões neoplásicas bem delimitadas exibindo uma proliferação de células mesenquimais variando de ovoides a fusiformes, vasos sanguíneos em formato de "chifre de veado", com ausência de figuras de mitoses. No caso 01 foi realizado análise imuno-histoquímica para auxiliar no diagnóstico. Foi observado uma marcação fraca e difusa de α-SMA e uma intensa e difusa imunopositividade para o Bcl-2 e CD34.Baseado nos achados histopatológicos e imuno-histoquímicos o diagnóstico de TFS foi estabelecido em ambos os casos. A baixa ocorrência e os achados clínicos inespecíficos do TFS oral podem dificultar o diagnóstico clínico. Além disso, as análises morfológicas e imuno-histoquimicas são essenciais para realização do diagnóstico diferencial com outras neoplasias mesenquimais.(AU)_

ABSTRACT

Introdução: A angina bolhosa hemorrágica (ABH) é uma condição rara, benigna e geralmente assintomática, caracterizada pelo surgimento súbito de bolhas preenchidas com sangue nas superfícies mucosas da cavidade oral e orofaringe. Objetivo: Este trabalho tem como propósito fornecer uma análise abrangente das características clínicas, etiológicas e histopatológicas da angina bolhosa hemorrágica, além de abordar métodos de diagnóstico e opções de tratamento. Materiais e métodos: Foi realizada uma busca por artigos científicos publicados de 2010 a 2023, nas bases de dados Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) e ScienceDirect. Foram coletados artigos em inglês e português utilizando as palavras-chave "angina bolhosa hemorrágica", "estomatite bolhosa hemorrágica benigna", "hemorrhagic bullous angina" e "benign hemorrhagic bullous stomatitis". Conclusão: A ABH é escassamente documentada na literatura, com muitos dados ausentes ou subnotificados. Embora seja uma condição benigna com rápida evolução espontânea, o procedimento diagnóstico deve ser rigoroso para descartar outras possíveis lesões.


Introduction: Hemorrhagic bullous angina (ABH) is a rare, benign and generally asymptomatic condition, characterized by the sudden appearance of blisters filled with blood on the mucous surfaces of the oral cavity and oropharynx. Objective: This work aims to provide a comprehensive analysis of the clinical, etiological and histopathological characteristics of hemorrhagic bullous angina, in addition to addressing diagnostic methods and treatment options. Materials and methods: A search was carried out for scientific articles published from 2010 to 2023, in the Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) and ScienceDirect databases. Articles were collected in English and Portuguese using the keywords "hemorrhagic bullous angina", "benign hemorrhagic bullous stomatitis", "hemorrhagic bullous angina" and "benign hemorrhagic bullous stomatitis". Conclusion: ABH is scarcely documented in the literature, with many data missing or underreported. Although it is a benign condition with rapid spontaneous evolution, the diagnostic procedure must be rigorous to rule out other possible lesions.

ABSTRACT

Introdução: o odontoma é considerado como um frequente tumor odontogênico benigno, podendo ser classificado em tipo composto ou tipo complexo. O cisto dentígero é o mais comum entre os cistos odontogênicos de desenvolvimento, onde envolve a coroa da unidade dentária no nível da junção amelocementária. Há poucos estudos na literatura do encontro das duas lesões, acometendo o mesmo local na cavidade oral. O diagnóstico pode ser constituído por exame clínico e de imagem. Objetivo: apresentar um caso clínico de odontoma composto e cisto dentígero em região de parassínfise mandibular esquerda abordando as caraterísticas clínicas destas duas lesões e as adequadas formas de tratamento. Relato de caso: paciente do sexo masculino, 16 anos de idade, compareceu ao ambulatório do Centro Odontológico da Escola Bahiana de Medicina e Saúde Pública (Salvador, Bahia), portando encaminhamento de ortodontista, solicitando exodontia da unidade dentária 33 inclusa associada a um odontoma. Ao realizar exames físicos e imaginológicos detectou-se a hipótese diagnóstica de odontoma composto associado a unidade dentária, envolto em folículo pericoronário ou cisto dentígero. Foi realizada biópsia excisional das duas lesões e exodontia da unidade. A análise histopatológica confirmou o diagnóstico para odontoma composto associado a cisto dentígero na unidade 33. Ao acompanhamento de 03 meses, paciente apresentou neoformação óssea da região de parassínfise mandibular, mediante a análise de novos exames imaginológicos. Discussão: há poucos estudos na literatura da associação entre as duas lesões, porém relatos afirmam que o odontoma pode ser encontrado associado aos cistos odontogênicos. Por conta da falta de maiores estudos dessa associação, há escassez de recomendações terapêuticas de acordo com faixa etária e extensão do acometimento das lesões. Considerações finais: lesões comumente assintomáticas, tem o diagnóstico constituído por exame clínico e avaliação de exames de imagem(AU)


Introduction: odontoma is considered a frequent benign odontogenic tumor and can be classified as a compound or complex type. The dentigerous cyst is the most common among developmental odontogenic cysts, where it involves the crown of the dental unit at the level of the cementoenamel junction. There are few studies in the literature on the meeting of the two lesions, affecting the same site in the oral cavity. The diagnosis can be made by clinical and imaging examination. Objective: to present a clinical case of compound odontoma and dentigerous cyst in the left mandibular parasymphysis region, addressing the clinical characteristics of these two lesions and the appropriate forms of treatment. Case report: male patient, 16 years old, attended the outpatient clinic of the Centro Odontológico da Escola Bahiana de Medicina e Saúde Pública (Salvador, Bahia), having been referred by an orthodontist, requesting extraction of the included dental unit 33 associated with an odontoma. Upon physical and imaging examinations, the diagnostic hypothesis of a compound odontoma associated with a dental unit, surrounded by a pericoronal follicle or dentigerous cyst, was detected. Excisional biopsy of the two lesions and extraction of the unit were performed. The histopathological analysis confirmed the diagnosis of compound odontoma associated with dentigerous cyst in unit 33. At the 03-month follow-up, the patient presented bone neoformation in the mandibular parasymphysis region, through the analysis of new imaging exams. Discussion: there are few studies in the literature on the association between the two lesions, but reports state that odontoma can be found associated with odontogenic cysts. Due to the lack of further studies on this association, there is a lack of therapeutic recommendations according to age group and extent of lesion involvement. Final considerations: commonly asymptomatic lesions, the diagnosis consists of clinical examination and evaluation of imaging tests(AU)

ABSTRACT

A ressecção é o tratamento de escolha para tratamento do ameloblastoma, este que é o tumor odontogênico mais comuns, excluindo os odontomas. A desregulação de diversos genes no desenvolvimento de dentes pode desempenhar papel em sua histogênese. Alguns eventos adversos podem ocorrer durante seu tratamento pós-operatório. Recidivas ocorrem porque o ameloblastoma tende a se infiltrar entre o trabeculado ósseo esponjoso intacto na periferia do tumor antes que a reabsorção óssea se torne radiograficamente evidente. Consequentemente, a margem real do tumor sempre se estende além da sua imagem radiográfica ou da margem clínica. Deiscência de sutura é uma complicação que pode ocorrer no pós-operatório imediato na qual as bordas da ferida, que estão unidas por uma sutura, acabam se abrindo, aumentando o risco de infecção e dificultando assim a cicatrização. Fratura de placa de reconstrução é um evento possível de ocorrer em tratamentos de grandes defeitos. O estresse causado pela modelagem da placa durante a conformação da placa, além da ação muscular são uns dos fatores que pode fragilizar o metal da placa. Outras complicações podem ocorrer como: assimetrias, parestesia temporária e permanente do nervo alveolar inferior e deficiência estética e funcional. As descrições destes eventos na literatura ajudam aos clínicos conhecer e tentá-lo preveni-lo e com saber tratar... (AU)


Resection is the treatment of choice for treating ameloblastoma, which is the most common odontogenic tumor, excluding odontomas. The dysregulation of several genes in the development of teeth may play a role in their histogenesis. Some adverse events may occur during your postoperative treatment. Relapses occur because ameloblastoma tends to infiltrate between intact cancellous bone trabeculae at the pe riphery of the tumor before bone resorption becomes radiographi cally evident. Consequently, the actual tumor margin always extends beyond its radiographic image or clinical margin. Suture dehiscence is a complication that can occur in the immediate postoperative period in which the edges of the wound, which are joined by a suture, end up opening, increasing the risk of infection and thus hindering healing. Reconstruction plate fracture is a possible event to occur in large de fect treatments. The stress caused by the modeling of the plate during the formation of the plate, in addition to muscle action, are one of the factors that can weaken the plate metal. Other complications may occur, such as: asymmetries, temporary and permanent paresthesia of the inferior alveolar nerve and aesthetic and functional deficiency.

ABSTRACT

Resumen Objetivo: El cementoblastoma es una neoplasia odontogénica benigna de origen mesenquimático relativamente poco frecuente que se asocia a las raíces de las piezas dentarias. Se considera que es la única neoplasia verdadera de origen cemental. El objetivo del presente trabajo es describir el caso clínico de un cementoblastoma de grandes dimensiones y realizar una revisión bibliográfica a fin de establecer pautas de diagnóstico y tratamiento, señalando sus diferenciales con patologías de similares características como la displasia cemento ósea y el fibroma cemento osificante. Caso clínico: Se describe el caso de un paciente pediátrico que presenta un aumento de volumen de considerables dimensiones asociado al primer molar permanente mandibular. Teniendo en cuenta las características clínicas y radiográficas, y con un diagnóstico presuntivo de cementoblastoma, se realizó la extirpación quirúrgica de la lesión junto con la pieza dentaria asociada, confirmándose el diagnóstico inicial por medio del estudio anatomopatológico.


Abstract Aim: Cementoblastoma is a relatively infrequent benign odontogenic neoplasia of mesenchymal origin that is associated with the roots of teeth. It is considered to be the only true cemental originated neoplasm. The objective of this article is to describe the clinical case of a large cementoblastoma and to carry out a bibliographical review to establish diagnostic and treatment guidelines, pointing out its differences with pathologies of similar characteristics, such as the cemento-osseous dysplasia and the cemento-ossifying fibroma. Clinical case: The case of a pediatric patient who presents a considerable increase in the volume associated with the mandibular first permanent molar is described. Considering the clinical and radiographic characteristics, and with a presumptive diagnosis of cementoblastoma, a surgical extraction of the lesion along with the associated tooth was performed, confirming the initial diagnosis by an anatomopathological study.

ABSTRACT

Background:Immunohistochemistry have had a huge impact on oral and maxillofacial pathology diagnosis. As a method it determines distribution and amount of certain cellular molecules via specific antigen-antibody reaction. Whereas in most cases a definitive diagnosis is achieved based on detailed hematoxylin and eosin cytomorphological analysis, along with clinical and radiological features, some challenging and equivocal neoplasms need to be further assessed with immunohistochemistry. Objective:This article reviews and updates immunohistochemistry technique fundamentals, its role and relevance in the diagnosis of common oral and maxillofacial lesions encountered in daily practice. Materials and methods: A literature review on the topic was carried out by searching pertinent and available papers on PubMed, ClinicalKey and Scielo platforms with no date restriction, up to 2022. Conclusion: Immunohistochemistry is an important tool that has been integrated into conventional histopathology and provides diagnostic assistance in the interpretation of common but equivocal neoplasms


Antecedentes: El uso de la inmunohistoquímica ha tenido un gran impacto en el diagnóstico de patología oral y maxilofacial. Como técnica, determina la distribución y la cantidad de ciertas moléculas celulares a través de una reacción antígeno-anticuerpo específica. Aunque en la mayoría de los casos se logra obtener un diagnóstico definitivo basado en el análisis cito morfológico con hematoxilina y eosina, junto con las características clínicas y radiológicas, algunas neoplasias microscópicamente equívocas deben evaluarsemás a fondo con inmunohistoquímica. Objetivo: Este artículo revisa los fundamentos básicos actuales de la técnica y su relevancia en el diagnóstico de algunas lesiones orales y maxilofaciales frecuentemente tratadas en la práctica clínica diaria. Materiales y Métodos: Se realizó una búsqueda y revisión de artículos científicos relacionados con el uso immunohistoquímica en patología oral y maxilofacial en PubMed, ClinicalKey y Scielo. Conclusión: La immunohistoquimica es una herramienta importante que ha sido integrada a la histopatología convencional y brinda asistencia diagnostica en la interpretación de neoplasias comunes pero equívocas

ABSTRACT

Odontogenic lesions are a heterogeneous group of diseases that presents differences in their biological behavior and the occurrence of variable inductive interactions. Calcifying odontogenic cyst (COC), or Gorlin's cyst, is a well-recognized example of these lesions. We describe a case of COC with AOT-like areas and highlights its morphological diversity. A 60-year-old pheoderma man presented with a large swelling in the anterior buccal region of the mandible. Panoramic radiography revealed a well-defined, unilocular, radiolucent lesion associated with important root resorption. Complete enucleation of the lesion was performed and the histopathological findings met the criteria for the diagnosis of COC, although the cyst exhibited unusual AOT-like features. The patient has been recurrence free for 6 months after surgery. COCs with AOT-like features are rare, and reflect the multipotentiality and complexity of the inductive effects of the odontogenic epithelium with the ectomesenchyme. Enucleation seems to be the most indicated treatment, similar to classical COC (AU)


As lesões odontogênicas são um grupo heterogêneo de patologias que apresentam diferenças no seu comportamento biológico, e ocorrência de interações indutivas variáveis. O cisto odontogênico calcificante (COC), ou cisto de Gorlin, é um exemplo bem conhecido destas lesões. Descrevemos um caso de COC com áreas adenomatóides e destacamos a sua diversidade morfológica. Paciente do sexo masculino, 60 anos de idade, apresentou um aumento de volume na região anterior da mandíbula. A radiografia panorâmica revelou uma lesão bem definida, unilocular e radiolúcida associada a uma reabsorção radicular importante. A enucleação completa da lesão foi realizada e os achados histopatológicos preencheram os critérios para o diagnóstico de COC, embora o cisto exibisse características adenomatóides pouco usuais. O paciente permanece livre de recidivas durante 6 meses após a cirurgia. Os COCs com características adenomatóides são raros, e refletem a multipotencialidade e complexidade dos efeitos indutivos do epitélio odontogênico com o ectomesênquima. A enucleação parece ser o tratamento mais indicado, semelhante ao COC clássico. (AU)

ABSTRACT

Introduction: Histopathological characterisation of benign and malignant lesions of the head and neck in a systematic and coherent way is an essential part of Oral Pathology and Oral Medicine. Objective: To describe the frequency and histopathological profile of connective tissue tumours in the head and neck region reported in an Indian institute. Methods: A retrospective analysis was made of the 10-year records of reports of biopsy samples of patients maintained by the department of oral pathology showing histopathological diagnosis of connective tissue neoplasms. The data obtained was compiled for age, gender, site and histopathology of the lesions. Results: Majority of the tumours were benign and patients were found to be in the 2nd or 4th decade of life with female preponderance. The most common benign tumour was fibroma where buccal mucosa was the commonest location and malignant tumour was osteosarcoma where mandible was the commonest site. While fibromas were seen among general adult population, osteosarcomas were more in the males (7.2 %) and in the younger population (< 20 years). The uncommon tumours among benign variety were leiomyoma and teratoma while in malignant category 1 case of undifferentiated sarcoma was reported. Conclusion: The findings in this study may be of help to oral and maxillofacial surgeons and general dentists in formulating diagnosis and rendering patient care in the existing local population.


Introducción: La caracterización histopatológica de las lesiones benignas y malignas de cabeza y cuello de forma sistemática y coherente es una parte esencial de la Patología Oral y la Medicina Oral. Objetivo: Describir la frecuencia y el perfil histopatológico de los tumores del tejido conjuntivo de la región de cabeza y cuello notificados en un instituto indio. Métodos: Se realizó un análisis retrospectivo de los registros de 10 años de informes de muestras de biopsia de pacientes mantenidos por el departamento de patología oral que mostraban diagnóstico histopatológico de neoplasias del tejido conectivo. Se recopilaron los datos obtenidos en cuanto a edad, sexo, localización e histopatología de las lesiones. Resultados: La mayoría de los tumores eran benignos y los pacientes se encontraban en la 2ª o 4ª década de la vida, con preponderancia del sexo femenino. El tumor benigno más frecuente fue el fibroma, cuya localización más frecuente fue la mucosa bucal, y el tumor maligno fue el osteosarcoma, cuya localización más frecuente fue la mandíbula. Mientras que los fibromas se observaron entre la población adulta general, los osteosarcomas fueron más frecuentes en los varones (7,2%) y en la población más joven (< 20 años). Los tumores menos frecuentes en la variedad benigna fueron el leiomioma y el teratoma, mientras que en la categoría maligna se registró un caso de sarcoma indiferenciado. Conclusiones: Los hallazgos de este estudio pueden ser de ayuda para los cirujanos orales y maxilofaciales y los odontólogos generales en la formulación de diagnósticos y la prestación de atención al paciente en la población local existente.

ABSTRACT

Introducción: el mixoma odontogénico es una neoplasia benigna, poco frecuente, de origen mesenquimal proveniente del órgano dentario, es localmente invasivo y no hace metástasis. Su localización más frecuente es a nivel de la mandíbula y poco frecuente en el maxilar. Objetivo: describir las características que presenta un mixoma odontogénico de larga data en el maxilar. Presentación del caso: paciente de sexo masculino de 23 años de edad, soltero, de profesión comerciante, acude a la Catedra de Patología Bucal de la Facultad de Odontología de la Universidad Nacional de Asunción por presentar una deformidad en la región facial del lado derecho, presente desde la infancia con crecimiento lento sin sintomatología dolorosa. Se realizó una biopsia incisional, tomando una muestra de más de 1 cm de la capsula tumoral para su estudio histopatológico; a partir de la cual se informa sobre un tumor odontogénico mesenquimal compatible con el mixoma odontogénico. Se realizó el tratamiento de una maxilectomía con márgenes de seguridad y el estudio anatomopatológico de todo el tumor extirpado confirmó el diagnóstico de Mixofibroma odontogénico de 2,5 cm de diámetro máximo. Conclusión: un diagnóstico precoz de tumores como los mixomas, que son de crecimiento lento e infiltrante, podría garantizar terapéuticas menos agresivas e invasivas como las del caso presentado, otorgando así mejor pronóstico como calidad de vida a los pacientes.


Introduction: Odontogenic myxoma is a rare benign neoplasm of mesenchymal origin originating from the dental organ, it is locally invasive and does not metastasize. Its most frequent location is at the level of the mandible and infrequently in the maxilla. Objective: To describe the characteristics of a long-standing odontogenic myxoma in the maxilla. Presentation of the case: Male patient, 23 years of age, single, businessman, came to the Department of Oral Pathology of the Faculty of Dentistry of the National University of Asuncion for presenting a deformity in the facial region on the right side, present since childhood with slow growth and no painful symptomatology. An incisional biopsy was performed, taking a sample of more than 1cm of the tumor capsule, for histopathological study; reporting a mesenchymal odontogenic tumor compatible with odontogenic myxoma. A maxillectomy treatment with safety margins performed and the anatomopathological study of the entire excised tumor confirmed the diagnosis of odontogenic myxofibroma with a maximum diameter of 2.5 cm. Conclusion: An early diagnosis of tumors such as myxomas, which are slow-growing and infiltrative, could guarantee less aggressive and invasive therapies such as those in the case presented, thus providing patients with a better prognosis and quality of life.

ABSTRACT

O cisto radicular é uma lesão inflamatória associada à necrose pulpar que ocorre frequentemente em maxila. Objetivo: Descrever um caso cirúrgico detalhado de Cisto Periapical Abscedado. Relato de Caso: paciente gênero feminino, 40 anos, hipertensa, diabética Tipo II, compareceu à clínica queixando-se de dor ao ingerir alimentos frios e quentes na região da maxila, lado esquerdo. Ao exame físico, observou-se destruição coronária e presença de fístula na região do elemento dentário 23. Ao exame radiográfico, observou-se uma área radiolúcida ovalada bem circunscrita com halo radiopaco envolvendo a região apical do elemento dentário 23. Frente ao aspecto clínico e radiográfico, foram sugeridas as hipóteses diagnósticas de abscesso periapical crônico, granuloma periapical ou cisto apical abscedado. Foi realizada a exodontia do elemento 23 seguida de enucleação cística. O diagnóstico histopatológico final foi de cisto abscedado. Após 5 meses de evolução observa-se mucosa íntegra e reparo ósseo alveolar. Conclusão: É imprescindível um exame clínico cuidadoso associado ao exame radiográfico e histopatológico para analisar minuciosamente o caso a fim de oferecer ao paciente melhores condutas de tratamento. O diagnóstico de lesões intraósseas associado ao correto tratamento interrompe a evolução do processo patológico, evita danos maiores e restabelece a condição de saúde dos pacientes... (AU)


The radicular cyst is an inflammatory lesion associated with pulp necrosis that often occurs in the maxilla. Objective: To describe a detailed surgical case of Abscessed Periapical Cyst. Case Report: female patient, 40 years old, hypertensive, type II diabetic, came to the clinic complaining of pain when ingesting cold and hot foods in the left side of the maxilla. On physical examination, coronary destruction and the presence of a fistula in the region of the tooth 23 were observed. The radiographic examination showed a well-circumscribed oval radiolucent area with a radiopaque halo involving the apical region of the tooth 23. In view of the clinical and radiography, the diagnostic hypotheses of chronic periapical abscess, periapical granuloma or abscessed apical cyst were suggested. Element 23 extraction was performed followed by cystic enucleation. The final histopathological diagnosis was an abscessed cyst. After 5 months of evolution, intact mucosa and alveolar bone repair are observed. Conclusion: A careful clinical examination associated with radiographic and histopathological data is essential to systematically analyze the case in order to offer the patient better treatment. The diagnosis of intraosseous lesions associated with the correct treatment interrupts the evolution of the pathological process, avoids further damage and restores the patients' health condition...

ABSTRACT

RESUMEN: En mucosa oral se pueden expresar múltiples lesiones y condiciones que se alejan de la normalidad las cuales deben ser sujeto de estudio y manejo con el fin de mejorar el pronóstico de los pacientes y su calidad de vida, siendo algunas veces motivo de consulta en servicios de urgencia. Un estudio observacional retrospectivo fue realizado con los datos de atención de urgencia del Hospital Barros Luco Trudeau, incorporando las consultas producto de hallazgos en mucosa oral. Se evaluaron los datos de 121 pacientes, 54 hombres y 67 mujeres entre 12 y 84 años, promedio de 45 años. La sospecha de Tumores malignos agrupó un 24,8 % de la muestra, siendo las lesiones en tejidos contiguos a paladar duro las más frecuentes dentro de este subgrupo, seguidos de cuadros de Estomatitis y Gingivitis (21,5 %), Granulomas (20,7 %) y Hiperplasias y Fibrosis (14,9 %). Los tejidos más afectados fueron el gingival con 47 casos (38,9 %) y el palatino con 39 casos (32,2 %). Nuestros resultados se condicen con lo expresado en la literatura donde en población adulta se tienden a identificar hallazgos asociados a daño crónico sobre los tejidos, con estímulos mecánico s de baja intensidad constantes y asociación con patologías base, mientras que en pacientes de primera y segunda década las lesiones traumáticas y asociadas a virus son más frecuentes. Es crítico que los profesionales conozcan las lesiones más frecuentes de identificar en la población, conociendo su etiología y manejo adecuado, junto con disponer de una red de trabajo continuo, realizando seguimiento del caso a lo largo del proceso diagnóstico.


ABSTRACT: Multiple lesions and conditions that are far from normal can be expressed in the oral mucosa, which should be the subject of study and management in order to improve the prognosis of patients and their quality of life, sometimes being a reason for consultation in emergency services. A retrospective observational study was carried out with the emergency care data from the Barros Luco Trudeau Hospital, incorporating the consultations resulting from findings in the oral mucosa. Data from 121 patients, 54 men and 67 women between 12 and 84 years old, average 45 years old, were evaluated. Suspicion of malignant tumors grouped 24,8 % of the sample, being the lesions in tissues adjacent to the hard palate the most frequent within this subgroup, followed by pictures of Stomatitis and Gingivitis (21.5 %), Granulomas (20.7 %) and Hyperplasias and Fibrosis (14.9 %). The most affected tissues were the gingival with 47 cases (38.9 %) and the palatal with 39 cases (32.2 %). Our results are consistent with what is expressed in the literature where, in the adult population, findings associated with chronic tissue damage tend to be identified, with constant low intensity mechanical stimuli and association with base pathologies, while in first and second patients In the decade, traumatic and virus-associated injuries are more frequent. It is critical that professionals know the most frequent injuries to identify in the population, knowing their etiology and proper management, along with having a continuous work network, monitoring the case throughout the diagnostic process.

ABSTRACT

Abstract Langerhans cells histiocytosis is a rare disease characterized by monoclonal proliferation and migration of special dendritic cells in a variety of organs, most commonly appears eosinophilic granuloma localized, often solitary, and bone lesions that occurs predominantly in pediatric patients. Although is most prevalent in children under the age of 15, this disorder presents in all ages and occurs at a rate of 2 to 5 cases per million per year. LCH is a complex entity; the clinic manifestations can mimic other common conditions and therefore a comprehensive evaluation is indicated. Since oral manifestations are frequent, the early diagnose of this pathology could be detected by dental professionals. The aim of this case report is to describe a case of LCH who initially was misdiagnosed and treated for a dental infection. This disease requires accurate histopathological diagnosis and timely treatment; hence it is necessary to raise awareness among dentists to avoid misdiagnose of oral manifestations of LCH.


Resumen La histiocitosis de las células de Langerhans es una enfermedad poco frecuente que se caracteriza por la proliferación monoclonal y la migración de células dendríticas especiales en una variedad de órganos; lo más común es que aparezca un granuloma eosinofílico localizado, a menudo solitario, así como lesiones óseas que se producen predominantemente en pacientes pediátricos. Aunque es más frecuente en los niños menores de 15 años, este trastorno se presenta en todas las edades y se produce a una tasa de 2 a 5 casos por millón al año. La HCL es una entidad compleja; las manifestaciones clínicas pueden imitar otras afecciones comunes y, por lo tanto, se indica una evaluación exhaustiva. Dado que las manifestaciones orales son frecuentes, el diagnóstico precoz de esta patología podría ser detectado por los profesionales de la odontología. El objetivo de este reporte de caso es describir un caso de HCL que inicialmente fue mal diagnosticado y tratado por una infección dental. Esta enfermedad requiere un diagnóstico histopatológico preciso y un tratamiento oportuno; por lo tanto, es necesario sensibilizar a los dentistas para evitar un diagnóstico erróneo de las manifestaciones orales de la HCL.

ABSTRACT

Introdução: Rânula é um fenômeno de extravasamento de muco, também chamado cisto de retenção de muco, que ocorre especificamente no soalho bucal. A origem da mucina extravasada é usualmente da glândula sublingual, podendo, porém, se originar do ducto da glândula submandibular ou, ainda, das glândulas salivares menores presentes no soalho de boca. Rânulas de dimensões maiores usualmente originam se do corpo da glândula sublingual. Relato de caso: Este trabalho descreve um caso em uma criança de 5 anos de idade com uma rânula em região lateral esquerda de língua, e discutir questões sobre o tratamento desta patologia. Considerações finais: Há várias formas de tratamento, sendo as mais usadas a marsupialização, concomitante ou não com a excisão cirúrgica da lesão e da glândula salivar envolvida... (AU)


Introduction: Ranula is a phenomenon of mucus leakage, also called mucus retention cyst, which occurs specifically in the mouth floor. The origin of the extravasated mucin is usually from the sublingual gland, but it can originate from the duct of the submandibular gland or even from the minor salivary glands it presents on the floor of the mouth. Larger sized ranulas usually arise from the body of the sublingual gland. Case report: This work is a case in a 5-year-old child with a ranula in the left tongue region, and discuss about the treatment of this pathology. Final considerations: There are several forms of treatment, the most used being marsupialization, concomitant or not with a surgical excision of the lesion and the involved salivary gland... (AU)
