ABSTRACT
O fibroma ossificante juvenil trabecular (FOJTr) é uma lesão fibro-óssea benigna rara de comportamento agressivo, alto potencial de recorrência, e acometimento no esqueleto craniofacial de crianças e adolescentes. Uma paciente do gênero feminino, 8 anos de idade, compareceu ao ambulatório de Patologia Oral e Maxilofacial da Universidade de Gurupi UNIRG para avaliação clínica de um aumento de volume na região de corpo da mandíbula do lado esquerdo. Não havia sintomatologia dolorosa e sequer desconforto. Nos exames de imagem (radiografia panorâmica e tomografia computadorizada) foram observados uma extensa área radiolúcida que se estendia desde o primeiro molar permanente com rizogênese incompleta até o incisivo central do lado oposto. Após a realização da biópsia incisional e laudos histopatológicos realizou-se a remoção completa da lesão incluindo os remanescentes decíduos sobrejacentes ao fibroma. Nas imagens de controle pós-operatório aos 90 dias (radiografia panorâmica e tomografia computadorizada), notou-se sinais de neoformação óssea com espessamento basilar e os germes dos dentes permanentes em franco desenvolvimento. Diante disso, ressalta-se a importância do conhecimento dos aspectos clínicos, radiográficos e histopatológicos para a realização de um correto diagnóstico e tratamento adequado afim de reduzir as altas taxas de recidivas...

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)

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)

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is the second most common odontogenic neoplasm. It’s incidence approximately 1% of all oral tumors and 18% of all odontogenic tumors. More than 80% of cases of ameloblastoma occur in mandible. The ameloblastoma occurs in three variants solid or multicystic, unicystic, and peripheral. A painless expansion of the jaws is the most common clinical presentation. The correct diagnosis can be easily made with the help of plain X-rays and tissue biopsy. The standard management of ameloblastoma is marginal resection but sometimes a large tumor requires complete resection of affected part. Untreated tumors may lead to tremendous facial disfigurement, a severe malocclusion and pathological fractures of the jaw. Here we present a case of a young man with the chief complaint of facial asymmetry. The orthopantomogram of the patient was showing a multilocular radiolucency with Buccal and lingual cortical expansion. A diagnosis was made on the basis of the biopsy as multicystic ameloblastoma, and resection of the mandible was carried out. The mandibular primary reconstruction was done with avascular bilateral iliac crest bone graft. Long term prognosis showed satisfactory healing and good facial esthetics.

This paper describes an exceptional case of an enormous complex odontoma affecting the mandibular symphysis of a 9-year-old boy. Because of its dimensions, the lesion produced cortical bone expansion, dental displacement and impactation, which are clinical signs very seldom described for odontomas. The lesion was surgically excised in a conservative way using an intraoral approach with local anesthesia. After 7 years of follow up, all teeth had erupted and the mandibular bone healed totally. Because of its radiographic mixed radiolucent and radiopaque appearance and its expansive growth, it is imperative to make the differential diagnosis of giant complex odontoma for other more aggressive mixed odontogenic tumors, such as ameloblastic fibro-odontoma, odotoameloblastoma and cystic calcified odontogenic tumor. Conservative approach appears to be indicated in the treatment of such lesions.
Descrevemos um caso excepcional de um odontoma complexo gigante afetando a sínfise mandibular em um menino de nove anos de idade. Devido à sua dimensão esta lesão produziu expansão da cortical óssea, deslocamento dentário e impactação, sinais clínicos muito raramente descritos para odontomas. A lesão foi extirpada cirurgicamente de forma conservadora, utilizando uma abordagem intra-oral com anestesia local. Depois de sete anos de seguimento todos os dentes se encontram erupcionados e o osso mandibular totalmente curado. Devido à sua aparência radiográfica, mista radiolúcida e radiopaca, e seu crescimento expansivo, é imperativo fazer o diagnóstico diferencial de odontoma complexo gigante para outros tumores odontogênicos mistos mais agressivos, como o fibro-odontoma ameloblástico, odotoameloblastoma e tumor odontogênico cístico calcificante. Uma abordagem conservadora parece ser indicada no tratamento dessas lesões.
