ABSTRACT

Objective: the present report describes the clinical, radiographic, and histopathological features of an ameloblastic fibro-odontoma (AFO) lesion. Case report: we report a clinical case of a 14-year-old boy with asymptomatic edema. Panoramic radiography detected a unilocular lesion with defined margins located in the posterior region of the mandible. The internal structure of the lesion presented several degrees of radiopacity with the involvement of the third molar. Cone-beam computed tomography revealed expanded buccal and lingual cortical bones, perforation of the lingual cortical bone, and displacement of the mandibular canal. AFO was suspected based on the radiographic and clinical characteristics. Total excision was performed and histologically examined, confirming the diagnosis of AFO. No recurrence occurred during a 24-month follow-up period. Final considerations: the evaluation of the clinical, radiographic, and histopathologic findings needs to be accurate for a correct diagnosis and appropriate treatment for case of AFO since the presentation is often asymptomatic.(AU)


Objetivo: o presente relato descreve as características clínicas, radiográficas e histopatológicas de uma lesão de fibro-odontoma ameloblástico (FOA). Relato de caso: relatamos o caso clínico de um menino de 14 anos com edema assintomático. A radiografia panorâmica detectou lesão unilocular com margens definidas e localizada na região posterior da mandíbula. A estrutura interna da lesão apresentava vários graus de radiopacidade com envolvimento do terceiro molar. A tomografia computadorizada de feixe cônico revelou as corticais ósseas vestibular e lingual expandidas, perfuração da cortical óssea lingual e deslocamento do canal mandibular. FOA foi a hipótese diagnóstica com base nas características radiográficas e clínicas. A excisão total foi realizada e examinada histologicamente, confirmando o diagnóstico de FOA. Nenhuma recorrência ocorreu durante um período de acompanhamento de 24 meses. Considerações finais: a avaliação das características clínicas, radiográficas e histopatológicas contribuíram para um diagnóstico correto e o tratamento adequado para o caso de FOA, uma vez que a lesão é frequentemente assintomática.(AU)

ABSTRACT

Objetivo: o fibroma ossificante trabecular juvenil (FOJT) é uma lesão fibro-óssea incomum, benigna, porém de comportamento agressivo. Ocorre, frequentemente, em crianças e adolescentes, com maior acometimento em maxila e mandíbula. O presente relato aborda os aspectos clínicos, imaginológicos, histopatológicos, imuno-histoquímicos e o tratamento de um caso de FOTJ. Além de discutir suas similaridades com o osteossarcoma de baixo grau e as alternativas para o seu diagnóstico. Relato de caso: paciente do sexo masculino, com 12 anos de idade, apresentando aumento de volume em mandíbula no lado esquerdo, perda de função mastigatória e de fala, com tempo de evolução de seis meses. Radiograficamente, a lesão apresentava aspecto unilocular, com limites definidos e de padrão misto. O tratamento consistiu em cirurgia de enucleação total da lesão, seguida de curetagem sob anestesia geral. A histopatologia e a ausência de marcação para MDM2 e CDK4 na imuno-histoquímica confirmaram o diagnóstico de FOTJ e excluíram o de osteossarcoma de baixo grau. No controle pós-operatório de 20 dias, o paciente relatou melhora da parestesia, da função mastigatória e da fala e ausência de dor. Não se observou recidiva no acompanhamento de 1 ano após a cirurgia. Considerações finais: a similaridade dos aspectos clínico, imaginológico e microscópico entre FOJT e osteossarcoma de baixo grau pressupõe o estudo imuno-histoquímico com os arcadores MDM2 e CDK4, minimizando equívocos no diagnóstico e orientando de forma mais eficiente o plano de tratamento adotado.(AU)


Objective: juvenile Trabecular Ossifying Fibromas (JTOF) are uncommon benign fibro-osseous lesions with a local aggressive behavior. They frequently occur in children and adolescents involving the jaw bones. This report addresses the clinical, imaging, histopathological, and immunohistochemical aspects and the treatment of a case of JTOF. In addition, it discusses similarities between JTOF and low-grade osteosarcomas and alternatives for their diagnosis. Case report: male patient, 12 years old, with a tumor in his left mandible, loss of masticatory function and speech, with a 6-month time course. Radiographically, the lesion had an unilocular aspect, with defined borders and a mixed image pattern. Treatment consisted surgical enucleation, followed by bone curettage, under general anesthesia. Histopathology presented fibrous stroma interspaced with bone trabeculae without signs of cellular malignancy. MDM2 and CDK4 markers in immunohistochemistry, confirmed the diagnosis of JTOF and excluded low-grade osteosarcoma. At the 20-day postoperative follow-up, the patient reported improvement in paresthesia, masticatory function and speech, and the absence of pain. Evaluation 1 year after surgery showed no signs of local recurrence. Final considerations: the similarity of clinical, imaging, and microscopic aspects between JTOF and low-grade osteosarcoma prompts an immunohistochemical study including MDM2 and CDK4 markers in order to improve final diagnosis and guide the treatment plan more efficiently.(AU)

ABSTRACT

Objective: To analyse the quality of life of patients receiving repair of bone defect with folded fibula flap after removal of mandibular ameloblastoma. Methods: The case data of 39 patients with ameloblastoma admitted to the First Affiliated Hospital of Zhengzhou University from August 2013 to April 2016 were retrospectively analysed, including 21 males and 18 females, from 18 to 58 years old. 3D printing and digital technology were used in flap preparation before surgery in all patients. The folded fibular flaps were used to repair mandibular defects and the implants were placed between 6-9 months after surgery. The short form-36 health survey questionnaire (SF-36) and the university of Washington quality of life questionnaire (UW-QOL) were applied to evaluate the quality of life of patients before surgery and at 6 months and 24 months after surgery. The higher the score, the better the condition. SPSS 20.0 was adopted for statistical analysis. Results: The SF-36 survey showed that the mean score of body role before surgery (72.4±11.7) was significantly higher than that at 6 months after surgery (39.6±11.1, t=23.580, P<0.05) or that at 24 months after surgery (59.8±6.4, t=8.358, P<0.001). Compared with the preoperative mean scores of Physical Pain (73.0±11.0), General Health (73.4±10.4) and Health Changes (79.2±3.9) before surgery, the mean scores Physical Pain (53.1±7.7), General Health (53.5±7.5) and Health Changes (63.9±11.7) at 6 months after surgery were decreased significantly respectively (t=13.068, 13.756 and 10.880, respectively, all P<0.05), but the mean scores Physical Pain (78.8±14.0), General Health (80.9±12.6) and Health Changes (84.4±4.6) at 24 months after surgery were increased significantly respectively (t=-2.904, -4.027 and -7.586, respectively, all P<0.05), with significant differences in the mean scores of Physical Pain, General Health and Health Changes between 6 and 24 months after surgery (t=-14.241, -16.490, -14.294, respectively, all P<0.001). The UW-QOL survey showed that the mean scores of chewing, language and taste functions decreased at 6 months after surgery (53.1±6.7, 53.0±7.7 and 62.2±9.9, respectively), but improved at 24 months after surgery (67.9±3.9, 63.9±2.9 and 68.4±11.1, respectively), with statistically significant difference (t=-16.765, -11.675 and 2.498, respectively, all P<0.001). Conclusion: The application of folded fibula flaps to repair bone defects after sugery of mandibular ameloblastoma can better meet the needs of language and chewing functions and improve the quality of life of patients.

ABSTRACT

Objetivo: relatar um caso raro de impacção de um incisivo decíduo inferior pela presença de odontoma composto, bem como descrever a sua abordagem clínica. Relato de caso: paciente do sexo masculino, com 4 anos de idade, apresentava ausência do incisivo lateral decíduo inferior esquerdo. O exame radiográfico mostrou impacção do incisivo não erupcionado próximo a estruturas radiopacas sugestivas de odontoma composto. O paciente foi acompanhado por dois anos, momento em que se realizou abordagem cirúrgica do caso. Após a cirurgia, a hipótese de diagnóstico de odontoma composto foi confirmada e com o acompanhamento ocorreu a erupção dos incisivos centrais permanentes inferiores. O paciente foi encaminhado para tratamento ortodôntico. Considerações finais: esse relato de caso aborda um caso raro de odontoma composto associado à não erupção de dente decíduo, uma vez que odontomas costumam ser detectados preferencialmente na segunda década de vida do paciente, sendo associados à impacção de dentes permanentes. Além disso, apresenta um protocolo de abordagem clínica para esses casos quando diagnosticados em idade precoce no paciente infantil.(AU)


Objective: to report a rare case of impaction of a primary mandibular incisor due to the presence of a compound odontoma and describe its clinical management. Case report: a 4-year-old boy presented with a "missing" primary left mandibular lateral incisor. Radiographs showed impaction of the unerupted incisor by adjacent radiopaque structures consistent with a compound odontoma. The patient was recalled periodically for 2 years, at which time surgical excision was performed. The diagnosis of compound odontoma was confirmed histologically, and the permanent mandibular central incisors erupted uneventfully; the patient was referred for orthodontic treatment. Final considerations: this case report describes an unusual case of compound odontoma associated with an unerupted deciduous tooth; odontomas are rare in this age range, occurring predominantly in the second decade of life and in association with impaction of permanent teeth. We also propose a protocol for clinical management of such early-onset cases.(AU)

ABSTRACT

O carcinoma espinocelular (CEC) representa o tumor mais frequente dentre todos os cânceres da cavidade oral, com uma média de idade de 60 anos e maior ocorrência no sexo masculino. A característica clássica da lesão é de um nódulo endurecida, com sinais e sintomas que se diferem de acordo com a região oral acometida, muitas dessas lesões são indolores, o que pode causar um retardo no diagnóstico e tratamento da doença. Objetivo: relatar um caso clínico de um paciente com CEC em soalho bucal, ressaltando a importância de o cirurgião-dentista reconhecer e diagnosticar essa doença em estágios iniciais. Relato de caso: paciente do sexo masculino, 60 anos de idade, faioderma, tabagista, foi encaminhado para avaliação de lesão indolor em soalho de boca. No exame clínico, observou-se lesão nodular endurecida em soalho de boca com aproximadamente 3 cm de diâmetro, com presença de placas leucoplásicas em sua extensão e associada à ulceração na região de rebordo alveolar. O exame radiográfico panorâmico mostrou reabsorção óssea na região de ulceração. Foram realizadas a biópsia incisional da lesão e a análise histopatológica, em que foi compatível com CEC. O paciente foi encaminhado para tratamento oncológico. Considerações finais: assim, é imprescindível ressaltar a importância de um adequado exame clínico, bem como do diagnóstico precoce destas lesões malignas, favorecendo um bom prognóstico ao paciente.(AU)


Squamous cell carcinoma (SCC) represents the most frequent tumor among all cancers of the oral cavity, with an average age of 60 years and greater occurrence in males. The classic characteristic of the lesion is a hardened nodule, with signs and symptoms that differ according to the affected oral region, many of these lesions are painless, which can cause a delay in the diagnosis and treatment of the disease. Objective: to report a clinical case of a patient with CPB on the oral floor, emphasizing the importance of the dental surgeon in recognizing and diagnosing this disease in early stages. Case report: male patient, 60 years old, phaderoderma, smoker, was referred for painless lesion on the floor of the mouth. On clinical examination, a hard nodular lesion was observed on the floor of the mouth, approximately 3 cm in diameter, with the presence of leukoplastic plaques in its extension and was associated with ulceration in the region of the alveolar ridge. The panoramic radiographic examination showed bone resorption in the ulceration region. Incisional biopsy of the lesion and histopathological analysis were performed, in which it was compatible with CPB. The patient was referred for cancer treatment. Final considerations: thus, it is essential to emphasize the importance of an adequate clinical examination, as well as the early diagnosis of these malignant lesions, favoring a good prognosis for the patient.(AU)

ABSTRACT

O fibroma ossificante (FO) é uma neoplasia fibro-óssea benigna da região craniofacial de origem odontogênica, formado a partir de células mesenquimais multipotentes do ligamento periodontal, as quais são capazes de formar osso, tecido fibroso e cemento. Acredita-se que exodontias prévias, infecções, trauma ou uma perturbação de origem congênita na maturação óssea poderiam servir como fatores predisponentes para o desenvolvimento do FO. Radiograficamente, as lesões de FO iniciais são representadas por uma imagem radiolúcida, unilocular, redonda ou oval, de margem bem circunscrita. No estágio tardio, o componente mineralizado é circundado por uma fina cápsula fibrosa representada por uma linha radiolúcida delgada, que envolve toda a lesão. O objetivo deste trabalho é discutir a abordagem cirúrgica de um FO localizado em região atípica da mandíbula. Relato de caso: paciente leucoderma, 18 anos de idade, sexo feminino, cursando com aumento de volume em região posterior mandibular direita. No exame de imagem, identificou-se uma lesão mista, bem definida, não corticalizada, medindo aproximadamente 3 cm x 2,5 cm. Após realização de biópsia incisional, confirmou-se o diagnóstico de FO. Sendo assim, optou-se pela curetagem acompanhada de uma osteotomia periférica da lesão e reabilitação da região com enxerto ósseo liofilizado, além da instalação de uma placa de reconstrução na base da mandíbula do sistema 2.4 mm. Considerações finais: É necessário ter conhecimento sobre as lesões de aspecto radiográfico misto, que podem fazer diagnóstico diferencial com o FO, para que possa ser realizada uma correta intervenção, visto que para cada lesão há uma abordagem diferente.(AU)


The ossifying fibroma (FO) is a benign fibro-osseous neoplasm of the craniofacial region of odontogenic origin, formed from multipotent mesenchymal cells of the periodontal ligament, which are capable of forming bone, fibrous tissue and cementum. It is believed that previous exodontia, infections, trauma or a disturbance of congenital origin in bone maturation could serve as predisposing factors for FO development. Radiographically, the initial FO lesions are represented by a radiolucent, unilocular, round or oval image with well circumscribed margin. In the late stage, the mineralized component is surrounded by a thin fibrous capsule represented by a thin radiolucent line, which surrounds the entire lesion. The objective of this work is to discuss the surgical approach of a FO located in the atypical region of the mandible. Case report: leucoderma patient, 18 years, female, it were possible to note a slight volume increase in the posterior mandible region. The imaging examination identified a mixed lesion, well defined, however non-corticalised, measuring about 3 cm x 2.5 cm. The patient was submitted to an incisional biopsy and the diagnosis of ossifying fibroma was confirmed. We opted for a curettage followed by a peripheral osteotomy of the lesion and rehabilitation of the region with lyophilized bovine bone graft, besides the installation of a rebuilding plate at the base of the mandible system 2.4mm. Final considerations: it is necessary to have knowledge about lesions of mixed radiographic appearance, which can make differential diagnosis with FO so that a correct intervention can be performed, since for each lesion we have a different approach.(AU)

ABSTRACT

Introdução: o cisto ósseo traumático (COT) é um pseudocisto que se apresenta assintomático e é descoberto frequentemente em exames de rotina. Outra lesão também presente nos maxilares é o odontoma, sendo dividido em dois subtipos, o composto e o complexo; os odontomas são geralmente descobertos como um achado acidental, visto que não apresentam sintomatologia. Objetivo: relatar um caso incomum de um COT, associado à odontoma composto (OC). Relato de caso: paciente do gênero masculino, 16 anos de idade, compareceu à clínica escola de odontologia da Universidade Federal de Campina Grande (UFCG), campus Patos, PB, referenciado pelo cirurgião-dentista após solicitar exame radiográfico para tratamento ortodôntico e observar lesão radiolúcida em região anterior da mandíbula. Durante a anamnese, o paciente não relatou nenhuma alteração sistêmica ou doença de base, mas relatou trauma de infância na região acometida. No exame clínico intraoral, não foi observado nenhum aumento de volume na região. Realizou-se palpação na região, não havendo relato de dor. Ao analisar a radiografia panorâmica, observou-se a presença de pequenas estruturas calcificadas com radiopacidade semelhante às estruturas dentárias, delimitada por uma linha radiolúcida, sugestiva de OC. Para melhor localização, delimitação, relação com estruturas anatômicas e planejamento cirúrgico da lesão, foi solicitado um exame de tomografia computadorizada de feixe cônico (TCFC). Considerações finais: com base nos achados clínicos e radiográficos, optou-se por abordagem cirúrgica da lesão cística e enucleação do OC, sob anestesia local. No pós-operatório de um ano, o paciente evoluiu satisfatoriamente sem queixas clínicas.(AU)


Introduction: traumatic bone cyst (TBC) is a pseudocyst that usually presents asymptomatically and is found frequently in routine exams. Another lesion also present in the jaws is odontoma. The odontoma is divided into two subtypes, the compound and the complex; odontomas are usually discovered as an accidental finding, since they do not present symptomatology. Objective: the present article aims to report an unusual case of a TBC associated with a composite odontoma. Case report: a 16-year-old male patient attended the Clinic School of Dentistry of the Universidade Federal de Campina Grande (UFCG), Patos-PB campus, referenced by the dentist after identify radiolucent lesion in the anterior region of the mandible on radiographic examination for orthodontic treatment. During the anamnesis, the patient did not report any systemic alteration or underlying disease, but reported trauma in the region affected in childhood. The intra oral clinical examination, was not observed any increase in volume in the region. Palpation was performed in the region, and there was no report of pain. When analyzing panoramic radiography the presence of small calcified structures with radiopacity similar to dental structures was observed, delimited by a radiolucent line, suggestive of compound odontoma. To better location, delimitation, compared with anatomy and surgical planning of the injury, it was requested an cone beam computed tomography (CBCT). Final considerations: based on the clinical and radiographic findings, we opted for a surgical approach to cystic lesion and enucleation of composite odontoma, under local anesthesia. In the one-year postoperative period, the patient progresses satisfactorily without clinical complaints.(AU)

ABSTRACT

RESUMEN: El Leiomioma es una neoplasia benigna originada en el tejido muscular liso por lo que puede manifestarse en cualquier región del cuerpo humano que contenga músculo liso, siendo el sitio más común el útero, la piel y en el tracto gastrointestinal. La escasa cantidad de tejido muscular liso en boca hace que su manifestación oral sea infrecuente, representando solo 0.06 % del total de este tipo de tumores. Los sitios más afectados suelen ser los labios, las mejillas, el paladar, la lengua y encías. Histológicamente se distinguen tres tipos: el Leiomioma Sólido, Angioleiomioma (Vascular) y Leiomioma Epitelioide (Leiomioblastoma). El origen de esta neoplasia en boca suele ser la túnica media de los vasos sanguíneos. El Leiomioma intraóseo suele ser aún menos frecuente, y con un diagnóstico diferencial complejo, con histopatología que en varias ocasiones no suele ser fácil de clasificar. Si bien es definida como un tumor benigno, su manifestación intraósea puede llegar a ser localmente agresiva y con un diagnóstico controversial, debiendo abordarse muchas veces como una neoplasia maligna. El objetivo de este artículo es presentar una revisión de la literatura de esta variante intraósea de Leiomioma situada en mandíbula, sus consideraciones clínicas y un algoritmo de tratamiento.


ABSTRACT: Leiomyoma is a benign neoplasm, the origin is the smooth muscle tissue that can be found in any area of the human body, which contains smooth muscle tissue. The most common regions it can be located, are the uterus, the skin and the gastrointestinal tract. The low quantity of muscle tissue in the mouth leads to infrequent oral manifestation, representing only 0.06 % of these tumors. The most affected regions are the lips, cheeks, palate, tongue and gums. The Histologic classification is: Solid Leiomyoma, Angioleiomyoma (vascular) and Epithelioid Leiomyoma (Leiomyoblastoma). The origin of this tumor in the mouth is the tunica media of the blood vessels. Nevertheless, and in spite of being defined as a benign tumor, it can be extremely aggressive, be subject to controversial diagnosis, and must often be treated as a malign neoplasm. The Intraosseous Leiomyoma is infrequent and presents a complicated differential diagnosis, with a histopathology that many times cannot be easily classified. The aim of this article is to present a review of intraosseous variant Leiomyoma in the mandible, the clinicians´ considerations and a treatment algorithm.

ABSTRACT

Osteochondromas are benign osteogenic tumors that can attain great size, which may require resection and additional treatment to restore the jaw's shape and function. In this report, an osteochondroma located on the mandibular ramus and neck of the condyle was resected and reconstructed simultaneously through a total joint replacement. After the surgery, the patient remains asymptomatic and recovers opening and closing ranges, phonation and the masticatory function. The immediate reconstruction after resection is a good alternative to avoid a second operation and the presurgical virtual planning ensures the complete removal of the lesion using cutting guides and covering the entire defect with a customized alloplastic joint prosthesis.


Los osteocondromas son tumores osteogénicos benignos que pueden alcanzar grandes tamaños, los cuales requieren de resección quirúrgica y generalmente de algún tratamiento adicional para restaurar la forma y la función mandibular. En este caso, un osteocondroma localizado en la rama mandibular y el cuello del cóndilo fue reseccionado y reconstruido simultáneamente a través de un reemplazo articular total. Después de la cirugía, el paciente permanece asintomático y recupera los intervalos de apertura y cierre, la fonación y la función masticatoria. La reconstrucción inmediata después de la resección es una buena alternativa para evitar una segunda operación, y la planificación virtual prequirúrgica garantiza la eliminación completa de la lesión utilizando guías de corte y cubriendo todo el defecto con una prótesis articular aloplástica personalizada.

ABSTRACT

Objetivo: relatar um caso de ameloblastoma unicístico, com intuito de descrever os seus aspectos clínicos, radiográficos e histopatológicos e a abordagem terapêutica, bem como discutir com base na literatura. Relato de caso: paciente do sexo feminino, 14 anos, procurou a clínica-escola do Curso de Odontologia da Universidade Estadual de Feira de Santana, acompanhada de sua genitora, referindo como queixa principal: "meu queixo tá inchado". No exame físico intrabucal, observou-se tumefação em região mandibular esquerda, circunscrita estendendo-se do dente 31 ao 35, com consistência endurecida a palpação e ausência do dente 33. Foi realizada uma descompressão cirúrgica e biópsia incisional. O diagnóstico histopatológico confirmou a presença de infiltração mural por epitélio ameloblástico. Após confirmado o diagnóstico de ameloblastoma unicístico do tipo mural, o tratamento de escolha foi enucleação e curetagem da lesão. Considerações finais: esse tumor, quando tratado de forma conservadora, apresenta prognóstico favorável. Técnicas alternativas cada vez mais conservadoras estão sendo utilizadas no seu tratamento. Ainda assim, é importante o acompanhamento clínico e radiográfico de longo prazo, devido ao risco de recorrência após longos períodos. (AU)


Objective: this study aimed to report a case of unicystic ameloblastoma to describe its clinical, radiographic, histopathological, and therapeutic aspects, as well as to discuss the literature. Case report: a 14-year-old female patient attended the clinic of the School of Dentistry of Feira de Santana State University, accompanied by her mother, with the main complaint of a swollen chin. The intraoral physical examination revealed tumefaction in the left mandibular region, circumscribed, extending from tooth 31 to 35, hard on palpation, and absence of tooth 33. A surgical decompression and incisional biopsy were performed, and the histopathological diagnosis confirmed the presence of mural infiltration by ameloblastic epithelium. After confirming the diagnosis of mural unicystic ameloblastoma, the treatment of choice was enucleation and curettage of the lesion. Final considerations: this tumor, when treated conservatively, presents a favorable prognosis. Increasingly conservative techniques are being used as alternative treatments of this condition. Nevertheless, long-term clinical and radiographic monitoring is important because of the risk of recurrence after long periods. (AU)

ABSTRACT

Objetivo: relatar um caso de ameloblastoma unicístico em região anterior de mandíbula, descrevendo os métodos diagnósticos utilizados e o tratamento empregado. Relato de caso: paciente do gênero feminino, com 40 anos de idade, compareceu ao serviço de Cirurgia e Traumatologia Bucomaxilofacial da Faculdade de Odontologia da Universidade Federal da Bahia, com queixas de aumento de volume em região anterior de mandíbula, com evolução de 10 meses. O exame de imagem revelou lesão unilocular extensa que expandia cortical óssea em região de mento. Optou-se pela biópsia excisional da lesão, sob anestesia geral. O exame do espécime obtido confirmou o diagnóstico de ameloblastoma unicístico, para o qual se decidiu pela manutenção da terapêutica inicial. A paciente segue em acompanhamento pela equipe, sem sinais de recidivas. Considerações finais: o manejo do ameloblastoma unicístico, por vezes, demanda a biópsia excisional da lesão, a fim de diferenciá-la dos cistos odontogênicos e de individualizar seu padrão histológico. A abordagem conservadora pode ser adotada, desde que um acompanhamento rigoroso seja procedido. (AU)


Objective: to report a case of unicystic ameloblastoma in the anterior region of the mandible, describing the diagnostic methods used and the treatment applied. Case report: a 40-year-old female patient attended the Oral and Maxillofacial Surgery and Traumatology Service of the School of Dentistry at the Federal University of Bahia, Brazil, complaining of increased volume in the anterior region of the mandible, with a 10-month evolution. Imaging tests revealed extensive unilocular lesion that expanded the cortical bone in the mental region. Excisional biopsy of the lesion was performed under general anesthesia. The examination of the specimen obtained confirmed the diagnosis of unicystic ameloblastoma, for which it was decided to maintain the initial therapy. The patient is still being followed-up by the team, with no signs of relapses. Final considerations: the management of unicystic ameloblastoma sometimes requires excisional biopsy of the lesion to differentiate it from odontogenic cysts and isolate its histological pattern. The conservative approach may be adopted if along with strict monitoring. (AU)

ABSTRACT

ABSTRACT: Central ossifying fibroma is a lesion in which diagnosis has proved intriguing and unclear for presenting clinical, radiographic, and even histopathological similarities to other types of lesions such as the fibrous dysplasia of bone and cement-bone dysplasia. It is a benign neoplasm of uncertain etiology and slow development in which the mandible is affected more frequently than the maxilla. We described a case of central cemento-ossifying fibroma involving the right mandible of a thirty-five-female patient by presenting its clinical, radiographic, and histological characteristic sand discussing some differential diagnoses.


RESUMEN: El fibroma cemento-osificante central es una lesión que requiere un diagnóstico diferencial ya que muestran similitud clínica, histológica y radiológica con la displasia fibrosa y con la displasia cemento-ósea. Esta lesión es un tumor benigno de etiología incierta, presenta crecimiento lento y afecta principalmente la mandíbula más que el maxilar. Se reporta un caso de un paciente de sexo femenino de 35 años, diagnosticada con fibroma cementoosificante central que le afectó el lado derecho de la mandíbula. Se describen las características clínicas, histológicas y radiológicas de la paciente y se discuten los diversos diagnósticos diferenciales.

ABSTRACT

Abstract Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor of the jaws, histologically characterized by the presence of agglomerates of cells with eosinophilic cytoplasm. The patient, a 62-year-old Caucasian woman, presented an intraosseous lesion in the mandibular symphysis. A clinical examination revealed a discrete volumetric increase with a hard consistency, palpable to extraoral and intraoral examinations. Imaging studies revealed an extensive radiolucent area, without defined limits, extending from the region of the right second premolar to the left canine. Incisional biopsy analysis indicated a diagnosis of CCOC. The treatment proposed was segmental resection of the mandible with a safety margin. After six months without recurrence, definitive mandibular reconstruction was performed using an iliac crest graft, followed by rehabilitation with implant-supported denture after five months. After three years of post-resection follow-up, the patient has shown no evidence of recurrence or metastasis. She continues to be under follow-up. To conclude, CCOC must be considered a malignant tumor with aggressive behavior. Previous studies have shown that resection with free margins is a treatment with a lower rate of recurrence. Nevertheless, long-term follow-up is necessary for such patients.

ABSTRACT

Abstract: Salivary duct injury can be idiopathic, iatrogenic, or post-trauma and may result in sialocele or fistula. Most injuries regress spontaneously and botulinum toxin A is one of several therapeutic possibilities. We report a case of iatrogenic injury to the parotid duct after Mohs' micographic surgery for a squamous cell carcinoma excision in the left jaw region, treated by injection of botulinum toxin type A. Although the fistula by duct injury can be self-limiting, botulinum toxin injection by promoting the inactivity of the salivary gland allows rapid healing of the fistula.

ABSTRACT

Here is described a case of ameloblastic fibrosarcoma (AFS) affecting the posterior mandible of a woman who was treated surgically and recovered without signs of recurrence or metastasis after 12 years of follow-up. Tumor sections were immunostained for cell cycle, epithelial and mesenchymal markers. Immunohistochemical analysis evidenced high Ki-67 positivity in stromal cells (mean of 20.9 cells/High power field). Epithelial cells displayed strong positivity for p53, p63 and cytokeratin 19. In addition to the case report, a systematic review of current knowledge is presented on the AFS’s clinical-demographic features and prognostic factors. Based on the review, 88/99 cases were diagnosed as AFS, 9/99 as ameloblastic fibro-odontosarcoma and 2/99 as ameloblastic fibrodentinosarcoma. All these lesions displayed very similar clinical-demographic and prognostic features. Moreover, the review provided evidence that first treatment, regional metastasis, distant metastasis and local recurrence were significant prognostic values for malignant odontogenic mesenchymal lesions. Based on the findings, segregation among ameloblastic fibrosarcoma, ameloblastic fibrodentinosarcoma and ameloblastic fibro-odontosarcoma seems illogical, considering all these lesions have similar predilections and outcomes.


Resumo Aqui é descrito um caso de fibrossarcoma ameloblástico afetando região posterior da mandíbula de uma mulher. Após o tratamento, a paciente ficou livre da doença durante os 12 anos de acompanhamento. Foi realizado imunohistoquimica para marcadores epiteliais, mesenquimais e do ciclo celular. Além disso, uma revisão sistemática de literatura também foi realizada, na tentativa de descobrir as características clínico-demográficas e fatores prognósticos da lesão. 88/99 casos foram diagnosticados como fibrossarcoma ameloblastico, 9/99 como fibro-odontosarcoma ameloblastico e 2/99 como fibrodentinosarcoma ameloblastico. Todas estas lesões exibem características clínico-demográficas e prognósticos muito semelhantes. Além disso, esta revisão forneceu evidências de que primeiro tratamento, metástases regionais, metástases à distância e recorrência local são valores prognósticos significativos para lesões odontogênicas mesenquimais malignas. A análise imunohistoquímica demonstrou elevada marcação positiva em células do estroma para Ki-67 (média de 20,9 células /HPF). As células epiteliais exibiram forte marcação para p53, p63 e citoqueratina 19. A segregação entre fibrosarcoma ameloblastico, fibrodentinosarcoma ameloblastico e fibro-odontosarcoma ameloblastico é ilógica, uma vez que todas essas lesões têm predileções e resultados semelhantes.

ABSTRACT

ABSTRACT Jawbone reconstruction after tumor resection is one of the most challenging clinical tasks for maxillofacial surgeons. Osteogenic, osteoinductive, osteoconductive and non-antigenic properties of autogenous bone place this bone as the gold standard for solving problems of bone availability. However, the need for a second surgical site to harvest the bone graft increases significantly both the cost and the morbidity associated with the reconstructive procedures. Bone grafting gained an important tool with the discovery of bone morphogenetic proteins in 1960. Benefit of obtaining functional and real bone matrix without need of second surgical site seems to be the great advantage of use bone morphogenetic proteins. This study analyzed the use of rhBMP-2 in unicystic ameloblastoma of the mandible, detailing its structure, mechanisms of cell signaling and biological efficacy, in addition to present possible advantages and disadvantages of clinical use of rhBMP-2 as bone regeneration strategy.


RESUMO A reconstrução óssea dos maxilares após ressecções tumorais é uma das tarefas mais difíceis para o cirurgião maxilofacial. As propriedades osteogênicas, osteoindutoras, osteocondutoras e não antigênicas do osso autógeno o colocam como o padrão-ouro para a solução de problemas de disponibilidade óssea. Entretanto a coleta do enxerto ósseo necessita de um segundo sítio cirúrgico, aumentando significativamente o custo e a morbidade associados ao procedimento reconstrutivo. A enxertia óssea ganhou uma excelente ferramenta com a descoberta das proteínas ósseas morfogenéticas na década de 1960. O benefício da obtenção de matriz óssea verdadeira e funcional, sem a necessidade de um segundo sítio cirúrgico, parece ser a grande vantagem do uso das proteínas ósseas morfogenéticas. Neste contexto, o objetivo deste estudo foi analisar a utilização da rhBMP-2 na regeneração óssea de ameloblastoma mandibular unicístico, detalhando sua estrutura, seus mecanismos de sinalização celular e sua eficácia biológica, além de apresentar potenciais vantagens e desvantagens da utilização clínica das rhBMP-2, enquanto estratégia regenerativa.
