ABSTRACT

Introdução: Os cistos e tumores odontogênicos são lesões que apresentam comportamento biológico heterogêneo e patogênese ainda não totalmente esclarecida. A Yes-associated protein (YAP) atua como um regulador transcricional de genes envolvidos na proliferação celular e na apoptose, participando da ativação de vias associadas ao crescimento cístico e à progressão neoplásica. Objetivo: Analisar a expressão imuno-histoquímica da proteína YAP e correlacioná-la com marcadores envolvidos na proliferação celular e na apoptose em lesões odontogênicas epiteliais benignas. Metodologia: A amostra consistiu de 95 casos de lesões odontogênicas - 25 cistos dentígeros (CDs), 30 CO não sindrômicos (COs), 30 AMB convencionais (AMB-Cs) e 10 AMB unicísticos (AMB-Us) -, além de 10 espécimes de folículo dentários (FD). Foi realizada coleta dos dados clinico-demográficos dos casos, bem como análise morfológica para melhor caracterização da amostra. Os cortes histológicos foram submetidos à técnica imuno-histoquímica através da utilização dos anticorpos YAP, ciclina D1, Ki-67 e Bcl-2, e a análise da expressão destes foi realizada quali-quantitativamente, mediante metodologia adaptada. Os dados coletados seguiram para análise descritiva e estatística (p ≤ 0,05). Resultados: Houve discreta predileção por mulheres (n = 55; 57,6%) e por indivíduos na faixa etária dos 21 aos 40 anos (n = 50; 47,6%), sendo a região posterior de mandíbula mais afetada (64%). A análise da imunoexpressão de YAP revelou maiores níveis de expressão em COs, especialmente nas camadas basal e parabasal, seguido dos AMB-Us e AMB-Cs, que demonstraram moderada imunorreatividade, predominantemente nas células periféricas. Além disso, houve diferenças significativas quanto à imunoexpressão de YAP entre os grupos analisados, com existência de correlações positivas e estatisticamente significativas entre YAP e ciclina D1 em CDs e AMB-Us, e entre YAP e Ki-67 em AMB-Us (p < 0,05). Todavia, entre a imunoexpressão YAP e Bcl-2, foi verificada ausência de correlação estatisticamente significativa. Conclusões: A YAP pode exercer influência sobre a proliferação celular do epitélio de cistos e tumores odontogênicos, auxiliando, assim, na progressão das diferentes lesões odontogênicas (AU).


Background: Odontogenic cysts and tumors present heterogeneous biological behavior, and their etiopathogenesis is not fully understood yet. Yes-associated protein (YAP) acts as a transcriptional regulator of genes involved in cell proliferation and apoptosis, activating pathways associated with cystic growth and neoplastic progression. Objective: To analyze the immunohistochemical expression of YAP protein and correlate it with markers involved in cell proliferation and apoptosis in benign epithelial odontogenic lesions. Methods: The sample consisted of 95 cases of odontogenic lesions - 25 dentigerous cysts (DCs), 30 non-syndromic odontogenic keratocyst (OKCs), 30 conventional AMB (C-AMBs), and 10 unicystic AMB (UAMBs) -, in addition to 10 specimens of dental follicles (DF). Clinicodemographic data collection was carried out, as well as morphological analysis for better characterization of the sample. The histological sections were submitted to the immunohistochemical technique using YAP, cyclin D1, Ki-67, and Bcl-2 antibodies, and their immunoexpression analysis was performed qualitatively and quantitatively, through an adapted methodology. The collected data were submitted for descriptive and statistical analysis (p ≤ 0.05). Results: There was a slight predilection for women (n = 55; 57.6%) and individuals aged between 21 and 40 years (n = 50; 47.6%), with the posterior region of the mandible as the most affected site (64%). Analysis of YAP immunoexpression revealed higher expression levels in OKCs, especially in the basal and parabasal layers, followed by U-AMBs and C-AMBs, which showed moderate immunoreactivity, predominantly in peripheral cells. In addition, there were significant differences in YAP immunoexpression between the analyzed groups, with positive and statistically significant correlations between YAP and cyclin D1 in DCs and U-AMBs, and between YAP and Ki-67 in U-AMBs (p < 0.05). However, between YAP and Bcl-2 immunoexpression, there was no statistically significant correlation. Conclusions: YAP may influence on the cell proliferation of odontogenic cysts and tumors epithelium, thus helping with the progression of the different odontogenic lesions (AU) .

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

Objetivo: Describir un caso de quiste odontogénico in- flamatorio cuya presentación imagenológica no es la habitual. Caso clínico: Acude a la clínica profesional de Pato- logía Oral de la Universidad Andrés Bello una paciente de género femenino de 13 años, sin antecedentes mórbidos, con un hallazgo radiográfico de lesión mixta ubicada entre los premolares inferiores derechos. Es derivada al posgrado de cirugía oral y maxilofacial para que le realicen una biopsia excisional de la lesión con una hipótesis diagnóstica de tumor odontogénico adenomatoide. Una vez realizado el estudio histopatológico, se define la lesión como quiste odontogénico inflamatorio, que por las características clínicas-radiográficas podría corresponder con un quiste residual de un diente tem- poral. Debido a la variabilidad en la presentación clínica e ima- genológica de las lesiones quísticas maxilofaciales, el estudio anatomopatológico es imprescindible para un correcto diag- nóstico y tratamiento (AU)


Aim: To present a case of inflammatory odontogenic cyst with unusual imaging presentation. Clinical case: A 13-year-old female patient, with no history of morbidity, with a radiographic finding of a mixed lesion located between the lower right premolars. The patient visited the professional Oral Pathology clinic of the Andrés Bello University and was referred to postgraduate oral and maxillofacial surgery for an excisional biopsy of the lesion, with a diagnostic hypothesis of adenomatoid odontogenic tu- mor. After the histopathological study, the lesion was defined as an inflammatory odontogenic cyst, which, based on clini- cal-radiographic characteristics, could be a residual cyst of a primary tooth. Due to the variability in the clinical and imaging pres- entation of maxillofacial cystic lesions, anatomopathological study is essential for correct diagnosis and treatment (AU)

ABSTRACT

The calcifying epithelial odontogenic tumor is a rare benign neoplasm that accounts for approximately 1% of all odontogenic tumors. Most of the cases occur in the posterior mandible, and a few involve the maxilla. Despite their relatively indolent biological behavior, tumors in the maxilla tend to grow fast. We report the case of a 33-year-old female patient exhibiting swelling in the right maxilla. An isodense area associated with an impacted supernumerary tooth was found on imaging examination. The histopathologic diagnosis was a calcifying epithelial odontogenic tumor. The treatment of choice was surgical removal of the lesion and associated dental elements. The patient has been followed up for 11 months and shows no signs of recurrence. Besides describing this case, we reviewed the literature on the association of calcifying epithelial odontogenic tumors with supernumerary teeth and found two case reports addressing this subject.

ABSTRACT

Introdução: as lesões odontogênicas (LOs) compreendem um grupo heterogêneo de patologias orais e maxilofaciais que apresentam características distintas. O objetivo do presente estudo foi identificar as características clínico--patológicas das LOs diagnosticadas em um hospital da região sul do Brasil. Materiais e métodos: foi realizado um estudo retrospectivo para levantamento dos casos com diagnóstico histopatológico de LOs no período entre 2007 e 2017. Os laudos dos pacientes foram avaliados para extração das características clínico-patológicas e dos diagnósticos histopatológicos de cada caso. Resultados: um total de 255 casos de LOs foram identificados. Destes casos, 197 (77%) cistos odontogênicos e 58 (23%) tumores odontogênicos foram coletados, sendo que somente um caso (0,39%) possuiu o diagnóstico de neoplasia odonto-gênica maligna. Os diagnósticos mais prevalentes foram cisto radicular (32,5%) e cisto dentígero (31,76%), seguidos de ceratocisto odontogênico (10,98%), odontoma (10%) e ameloblastoma (10%). A maioria dos casos acometeu mandíbula (53,7%), com uma discreta predileção pelo sexo feminino (51%). A média de idade foi de 34±20,53 anos. Discussão: os dados apresentados corroboram com a literatura no que se refere à raridade do diagnóstico de tumores odontogênicos. Conclusão: o presente estudo demonstrou as principais características clínico-pato-lógicas de LOs diagnosticadas em um hospital no sul do Brasil, contribuindo para um maior conhecimento do perfil destas lesões.


Introduction: odontogenic lesions (OLs) represent a heterogeneous group of oral and maxillofacial patho-logies presenting distinct characteristics. The present study aimed to identify the clinical and pathological characteristics of OLs diagnosed in a southern Brazilian hospital. Materials and methods: a retrospective study was performed to evaluate cases with histopathological diagnosis of OLs identified in the period between 2007 and 2017. The patient's medical records were evaluated in order to obtain the clinical and pathological charac-teristics and the histopathological diagnosis from each case. Results: a total of 255 cases of OLs were identified. From these, 197 (77%) odontogenic cysts and 58 (23%) odontogenic tumors were surveyed, with only one case (0,39%) of a malignant odontogenic neoplasm. The most prevalent diagnosis were radicular cyst (32.5%) and den-tigerous cyst (31.76%), followed by odontogenic keratocyst (10.98%), odontoma (10%) and ameloblastoma (10%). The majority of the cases affected the mandible (53.7%) with a slight preference by female individuals (51%). The mean age was 34±20.53 years old. Discussion: the presented data are in accordance with the literature regarding the rarity of the diagnosis of odontogenic tumors.Conclusion: the present study demonstrated the main clinical and pathological characteristics of OLs diagnosed in a southern Brazilian hospital, contrib-uting to a better understanding of these injuries profiles.

ABSTRACT

Este artigo descreve a dificuldade em diagnosticar um cisto folicular inflamatório na área anterior da mandíbula em um menino com dentinogênese imperfeita tipo I (DI-1). Um menino de 6 anos de idade, com DI-1, procurou tratamento devido ao comprometimento estético. O exame radiográfico revelou uma lesão periapical envolvendo os dentes decíduos incisivo central e lateral direitos. Esses dentes foram extraídos sem intercorrências. Após três meses, a criança se queixou de dor em um edema de cor azulada na mesma área. O diagnóstico diferencial foi de cisto folicular e a lesão foi acompanhada. Como os sinais e sintomas persistiram, o tratamento de escolha foi a descompressão da lesão, seguido por irrigação abundante e curetagem das paredes da lesão. O acompanhamento clínico e radiográfico, mostrou, após 6 meses, remissão da lesão, reparo ósseo, e erupção ativa dos incisivos permanentes. As características incomuns deste caso, fizeram com que o diagnóstico de cisto folicular inflamatório fosse dificultado.


This article reports the difficulties in diagnosing an inflammatory follicular cyst in the mandibular anterior area of a boy with type 1 dentinogenesis imperfecta (DI-1). A 6-year-old boy, with DI-1, sought treatment due to esthetic complaints. The radiographic examination revealed a periapical lesion involving the right primary central and lateral incisors. These teeth were extracted with no complications. After three months, the boy complained of pain in a blue-black edema in the same area. The differential diagnosis was of follicular cyst and the lesion was followed-up. As the signs and symptoms persisted, the treatment of choice was to decompress the lesion, followed by copious irrigation, and lesion's wall curettage. After six months, the clinical and radiographic follow-up showed lesion remission, bone repair, and active eruption of permanent incisors. The uncommon characteristics of the case make the diagnosis of inflammatory follicular cyst difficult.

ABSTRACT

Introdução: o Cisto Odontogênico Calcificante (COC) é um cisto odontogênico raro e indolor, que causa destruição óssea medular e expansão óssea cortical, sendo relatado pela primeira vez por Gorlin, em 1962. Objetivo: neste artigo relatamos um caso de COC na região mais rara de sua aparição, que é a região posterior da maxila em um jovem de apenas 15 anos. Relato de Caso: o paciente foi internado com um inchaço extra-oral, que cresceu lentamente durante os 8 meses anteriores; na cavidade bucal, também foi observado edema na região dos dentes 26, 27 e 28 e também acentuada mobilidade; radiograficamente, havia área radiolúcida unilocular com algumas áreas radiopacas (como uma casca alaranjada). Os achados histológicos observados incluem proliferação de células fantasmas e células basais colunares, semelhantes a ameloblastos e células com camadas superficiais frouxas. Conclusão: o paciente foi submetido à enucleação com curetagem de cisto como tratamento; devido a altas taxas de recorrência, o paciente teve um acompanhamento a cada três meses por um período de 2 anos, sem sinais de recidiva.


Introduction: Calcifying Odontogenic Cyst (COC) is an uncommon and painless odontogenic cyst, that causes bone marrow destruction and cortical bone expansion. It was first reported by Gorlin, in 1962. Objective: in this article, we report a case of COC in the rarest region of its appearance, which is the posterior region of the maxilla in a young man who is only 15 years old. Case Report: the patient was admitted with an extraoral swelling that grew slowly during the previous 8 months; in the oral cavity, edema was also observed in the region of the teeth 26, 27 and 28, and also marked mobility; radiographically, there was unilocular radiolucent area with some radiopaque areas (like an orange skin). The histological findings observed include proliferation of phantom cells, and columnar basal cells, similar to Ameloblasts and cells with loose superficial layers. Conclusion: the patient underwent enucleation with cyst curettage as a treatment; due to high rates of recurrence the patient had a follow up every three months for a period of 2 years without signs of relapse.

ABSTRACT

El Quiste Odontogénico Calcificante (QOC) es una patología poco común que afecta en iguales proporciones a ambos se-xos, sin clara predilección por maxilar o mandíbula, es frecuentemente visto en asociación con dientes incluidos, así como otras patologías con las que puede compartir ciertas características especialmente radiológicas. El presente caso trata del manejo de un paciente masculino de 16 años de edad atendido en la clínica de cirugía oral y maxilofacial de la Universidad Nacional Autónoma de México, asintomático, con una lesión en mandíbula de importantes dimensiones, radiográficamente presentó una lesión radiolúcida de aproximadamente 4 cm, bordes definidos, abarca desde distal del 2do molar hasta el án-gulo y parte de la rama mandibular del lado izquierdo. Requirió un abordaje amplio que permita el tratamiento de la lesión y la prevención de una fractura asociada, así como un tratamiento que permita cubrir la posibilidad de una probable lesión tipo ameloblastoma más agresiva que el diagnóstico histopatológico no descartaba por completo. El paciente a 8 meses de seguimiento ha presentado una favorable evolución sin datos clínicos o radiográficos de recidiva, con adecuada función y estética.


Calcifying Odontogenic Cyst (COC) is a rare pathology that affects both sexes in equal proportions, without clear prefer-ence for maxilla or mandible. It is frequently seen in association with teeth included, as well as shares certain particularly radiological features with other diseases. The present case deals with the management of a 16-year-old male patient treated at the oral and maxillofacial surgery clinic of the Universidad Nacional Autónoma de Mexico, asymptomatic, with a jaw in-jury of important dimensions, radiographically presented a radiolucent lesion of approximately 4 cm, defined edges, covers from distal of the 2nd molar to the angle and part of the mandibular branch on the left side. It required a wide approach that allows the treatment of the lesion while simultaneously preventing an associated pathologic fracture. The treatment should also cover the possibility of a more aggressive ameloblastoma type lesion than the histopathological diagnosis did not rule out completely. The patient at 8 months of follow-up had a favorable evolution without clinical or radiographic evidence of recurrence, with adequate function and aesthetics.

O presente relato de caso diz é ao respeito à gestão de um paciente homem de 16 anos de idade tratado na clínica de cirurgia oral e maxilo-facial da Universidade Au-tônoma do México, assintomático, com uma lesão na mandíbula de dimensões importantes, radiografia mostrou uma lesão radiolúcida de aproximadamente 4 cm, bordas definidas, afetando desde o distal do 2º molar até o ângulo e parte do ramo mandibular do lado esquerdo. Foi necessária uma ampla abordagem que permita o tratamento da lesão e prevenção de uma fratura associada, além disso um tratamento que irá abranger a possibilidade de lesão provavelmente tipo ameloblastoma mais agressivo que o diagnóstico histopatológico não descartou completamente. O paciente aos 8 meses de seguimento teve uma evolução favorável sem dados clínicos ou radiográficos de recorrência, com função e estética adequadas.

ABSTRACT

ABSTRACT: The appearance of mixed odontogenic tumors into the oral cavity is a rare event. It is considered that some mixed tumors are only a stage in the complete development of a hamartomatous formation such as ameloblastic fibroodontoma and odontoma. Both pathologies share in common cellular elements which at one point makes them indistinguishable from each other. We present the case of a 21 year old patient who showed a mandibular growth whose histological elements present characteristics of both pathologies. The treatment was surgical excision of the lesion. There were no complications or recurrences to periodic reevaluation.


RESUMEN: La aparición de tumores odontogénicos mixtos en la cavidad oral es un evento raro. Se considera que algunos tumores mixtos son solo una etapa en el desarrollo completo de una formación hamartomatosa como el fibro-odontoma ameloblástico y odontoma. Ambas patologías comparten elementos celulares comunes que en un punto los hacen indistinguibles entre sí. Presentamos el caso de un paciente de 21 años que mostró un crecimiento mandibular cuyos elementos histológicos presentan características de ambas patologías. El tratamiento fue la escisión quirúrgica de la lesión. No hubo complicaciones o recurrencias a la reevaluación periódica.

ABSTRACT

O cisto odontogênico calcificante (COC) é considerado como condição patológica benigna de ocorrência rara em maxila e mandíbula, caracterizado por revestimento cístico de células epiteliais odontogênicas, contendo células fantasmas com propensão a regiões de calcificação. Neste artigo, descreveu-se a configuração clínica e histopatológica do COC por meio de relato de caso submetido a tratamento cirúrgico e acompanhamento pós-operatório. Paciente de 11 anos apresentou aumento de volume em região maxilar à esquerda, próxima ao sulco nasolabial e sem sintomatologia dolorosa. Os exames radiográficos indicaram lesão radiolúcida, bem circunscrita e expansiva em maxila, que foi submetida a enucleação associada a ostectomia marginal das paredes corticais ósseas. O histopatológico revelou revestimento cístico com epitélio odontogênico ameloblástico, ninhos espalhados de células fantasmas e regiões eosinofílicas de material compatível com dentinóide. Evidenciou-se, assim, perfil clínico de COC, que pode ser confundido com outras lesões císticas ou tumorais, sendo essencial o diagnóstico por meio de análise histopatológica. A abordagem cirúrgica proporcionou adequado diagnóstico e tratamento. Após acompanhamento clínico e radiográfico, não houve recorrência do COC.


Calcifying odontogenic Cyst (COC) has been considering as benign pathological ill and rare occurrence in maxilla and mandible, there been showed odontogenic epithelial cystic lining demonstrating ghost cells with a propensity to calcify. In this article, we described the clinical and histopathological features from case reported who had undergone surgical approach and postoperative follow-up. A 11 year-old-girl had presented volumetric increased in left maxilla area near nasolabial fold. The radiography images had indicated radiolucent lesion, well-circumscribed and wide on cortical maxillary bone, which was undergone enucleation associated with marginal osteotomy on the bone cortical walls. The histopathological features showed cystic lining with odontogenic epithelium containing ghost cells and some areas with eosinophilic matrix material compatible dentinoid. Thus, it was evidenced a clinical features of COC which could be confused with other cystic or tumoral lesions, there being essential on diagnosis and treatment. After clinical and radiographic follow-up during 07 years, there was no recurrence of the COC.

ABSTRACT

Calcifying cystic odontogenic tumor (CCOT) is defined as an odontogenic cyst-like benign neoplasm that characteristically contains several ghost cells, ameloblastoma-like epithelium, and occasional calcification. Ghost cell odontogenic carcinoma (GCOC), a malignant form of CCOT, is an exceptionally rare malignant tumor. In this report, we present a case of a 53-year-old man whose chief complaint was a solitary mass on the right mandible area. The mass was completely removed through an extraoral surgical approach and reconstructive surgery was performed in two phases.

ABSTRACT

This review article aimed to introduce a category of jaw lesions associated with impacted tooth. General search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and well-recognized textbooks were used to find relevant studies using keywords such as "jaw lesion", "jaw disease", "impacted tooth", and "unerupted tooth". More than 250 articles were found, of which approximately 80 were broadly relevant to the topic. We ultimately included 47 articles that were closely related to the topic of interest. When the relevant data were compiled, the following 10 lesions were identified as having a relationship with impacted tooth: dentigerous cysts, calcifying odontogenic cysts, unicystic (mural) ameloblastomas, ameloblastomas, ameloblastic fibromas, adenomatoid odontogenic tumors, keratocystic odontogenic tumors, calcifying epithelial odontogenic tumors, ameloblastic fibro-odontomas, and odontomas. When clinicians encounter a lesion associated with an impacted tooth, they should first consider these entities in the differential diagnosis. This will help dental practitioners make more accurate diagnoses and develop better treatment plans based on patients' radiographs.

ABSTRACT

Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated. Afterward, surgical enucleation was performed. The size of the lesion continued to shrink after marsupialization, and the maxillary sinus restored its volume. This patient has been followed-up for 3 years after the surgery, and there have not been any signs of recurrence.

ABSTRACT

The eruption cyst is a benign soft tissue anomaly that may occur during eruption of deciduous or permanent teeth. It is usually asymptomatic and its treatment involves clinical follow-up of dental eruption. However, it may become infected or cause discomfort and pain. In such cases, surgical treatment is recommended. The present report aimed to describe a clinical case of eruption cyst located on the deciduous mandibular incisors' area of a four-month-old female infant since her birth. After surgical treatment a change was observed in the position (rotation) of the tooth associated with the cystic lesion. Rotation of the mandibular incisor persisted during the deciduous dentition development.


O cisto de erupção é uma anomalia benigna de tecidos moles que pode ocorrer durante a erupção dos dentes permanentes ou decíduos. Ele é geralmente assintomático e seu tratamento envolve acompanhamento clínico da erupção dental. No entanto, ele pode se tornar infectado ou causar desconforto e dor. Em tais casos, é recomendado tratamento cirúrgico. O presente relato teve como objetivo descrever um caso clínico de cisto de erupção localizado na área dos incisivos inferiores decíduos presente em um bebê de quatro meses de idade desde seu nascimento. Após o tratamento cirúrgico foi observada uma mudança na posição (rotação) do dente associado com a lesão cística. A rotação do incisivo inferior persistiu durante o desenvolvimento da dentição decídua.

ABSTRACT

Calcifying cystic odontogenic tumor (CCOT) are uncommon benign slow-growing cysts of developmental origin partly exhibiting characteristics of a neoplasm. Until date, the exact behavior of CCOT had been enigmatic and still the lesion portrays a platform to be debatable. The lesion has been reviewed and readdressed from the date first reported about its diverse clinical and histopathological features. The name of the lesion itself has undergone extensive review for the same reason. We report a case of calcifying odontogenic cyst in the mandible with a review of the literature. This paper also highlights the update on nomenclature and classification.

ABSTRACT

The present article reports the case of a calcifying odontogenic cyst Type I variant in the maxilla of a 65-year-old woman. The lesion is unusual in that it has features of a cyst but also has many characteristics of solid neoplasm. It is classified into 2 types Type I-cystic variant and Type II-solid tumor variant. The calcifying odontogenic cyst may present some problems of differential diagnosis, both clinically and histopathologically. The histopathologic examination showed that structures characteristic of calcifying odontogenic cyst. The lesion was benign. After surgical removal of the cyst, the wound healed uneventfully, and the region was free of symptoms.

ABSTRACT

O Tumor Odontogênico Cístico Calcificante ou Cisto de Gorlin é uma lesão odontogênica rara, descrita como neoplasia cística benigna de origem odontogênica, que apresenta comportamento clínico variável. Sua patogênese permanece desconhecida, embora comumente seja aceito que se desenvolva a partir de remanescentes do epitélio odontogênico, presentes na da mandíbula, maxila e gengiva. O Objetivo deste artigo é relatar o caso clínico de tumor quístico odontogénico calcificante asociado com odontoma. Paciente do gênero masculino, 11 anos de idade, que procurou o Serviço de Cirurgia e Traumatologia Bucomaxilofacial do Hospital Santo Antônio-OSID/Salvador-BA, apresentando aumento de volume intrabucal indolor, na região de corpo mandibular esquerdo. No exame imaginológico observou-se lesão radiolúcida unilocular, bem delimitada, estendendo-se da região de incisivo lateral até primeiro pré-molar inferior esquerdo, associado à massa radiopaca em seu interior além de unidade supranumerária deslocada para basilar da mandíbula. Foi realizada a biópsia excisional da lesão, constatando-se o diagnóstico de tumor odontogênico cístico calcificante associado à odontoma. O paciente encontra-se sem sinais de recidiva, com dois anos de acompanhamento em tratamento ortodôntico. O conhecimento das características da lesão, um exame clínico detalhado e a solicitação de exames complementares são fundamentais para um diagnóstico criterioso, com a finalidade de oferecer ao paciente o tratamento mais adequado, que atualmente consiste na enucleação total da lesão, obtendo-se um bom prognóstico, raramente com relatos de recidiva(AU)

ABSTRACT

Calcifying epithelial odontogenic tumors (CEOTs) and ghost cell odontogenic tumors (GCOTs) are characteristic odontogenic origin epithelial tumors which produce calcifying materials from transformed epithelial tumor cells. CEOT is a benign odontogenic tumor composed of polygonal epithelial tumor cells that show retrogressive calcific changes, amyloid-like deposition, and clear cytoplasm. Differentially, GCOTs are a group of transient tumors characterized by ghost cell presence, which comprise calcifying cystic odontogenic tumor (CCOT), dentinogenic ghost cell tumor (DGCT), and ghost cell odontogenic carcinoma (GCOC), all derived from calcifying odontogenic cysts (COCs). There is considerable confusion about COCs and GCOTs terminology, but these lesions can be classified as COCs or GCOTs, based on their cystic or tumorous natures, respectively. GCOTs include ameloblastomatous tumors derived from dominant odontogenic cysts classified as CCOTs, ghost cell-rich tumors producing dentinoid materials as DGCTs, and the GCOT malignant counterpart, GCOCs. Many authors have reported CEOTs and GCOTs variably express keratins, beta-catenin, BCL-2, BSP, RANKL, OPG, Notch1, Jagged1, TGF-beta, SMADs, and other proteins. However, these heterogeneous lesions should be differentially diagnosed to allow for accurate tumor progression and prognosis prediction.
