Resumo: | Purpose: Desmoplastic Ameloblastoma (DA) is a rare variant of ameloblastoma, with specific clinical, imaginological and histopathological features. The biologic profile of this tumor is not fully understood because of the limited number of reported cases. The purpose of this paper is to report a case of DA mimicking a periapical lesion. Case Description: This tumour appeared in the anterior region of the left upper jaw of a 24-year-old female, between left lateral incisor and canine. The lesion was painless and only a slight swelling of the hard palate mucosa was noted. Radiographically, a well-delimited peak-like radiolucent area promoting root divergence was observed. The lateral incisor failed in responding positively to the pulp tests. Provisional diagnosis of radicular cyst versus fissural cyst was established and surgical enucleation followed by curettage was carried out. Histological examination of the specimens revealed proliferation of nests and cords of compressed odontogenic epithelium immersed in a densely collagenized stroma, associated to a few irregular bone trabeculae. Conclusion: These features were consistent with DA. The presence of a pulpally necrotic incisor and the atypical radiographic appearance obscured the disease. Despite the high rates of recurrence, no clinical or radiographic sign of reincidence of the tumor was detected one year later. |

O perfil biológico deste tumor não é totalmente compreendido, devido ao número limitado de casos notificados. O objetivo deste trabalho é relatar um caso de AD simulando uma lesão periapical. Descrição do caso: Este tumor apareceu na região anterior da maxila esquerda numa paciente do gênero feminino de 24 anos de idade, entre o incisivo lateral esquerdo e o canino. A lesão era indolor e apresentava apenas um ligeiro inchaço da mucosa do palato duro. Radiograficamente, uma área radiolúcida bem delimitada que promovia a divergência radicular foi observada. O incisivo lateral respondeu negativamente aos testes pulpares. Diagnóstico provisório de cisto radicular versus cisto fissural foi estabelecido e enucleação cirúrgica seguida de curetagem foi realizada. O exame histológico das amostras revelou a proliferação dos ninhos e cordões de epitélio odontogênico comprimidos imersos em um estroma densamente colagenizado, associada a um trabeculado ósseo levemente irregular. Conclusão: Estas características eram consistentes com AD. A necrose pulpar do incisivo e o aparecimento radiográfico atípico mascararam a real natureza da doença. Apesar das altas taxas de recorrência, nenhum sinal clínico ou radiográfico de recidiva do tumor foi detectado um ano mais tarde.EDIPUCRS - Editora Universitária da PUCRS2010-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articlerelato de casoinfo:eu-repo/semantics/otherapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/6333Revista Odonto Ciência; Vol. 25 No. 3 (2010); 306 - 309Revista Odonto Ciência; v. 25 n. 3 (2010); 306 - 3091980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/6333/5554https://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/6333/5555https://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/6333/5556Santos, Esaú Pinheiro dosAraújo, Francisco Emanuel NascimentoValido, Daisy PereiraLima, Sônia OliveiraCavalcanti Júnior, Ricardo Luiz AlbuquerqueSoares, Andrea Ferreira Ferreirainfo:eu-repo/semantics/openAccess2013-11-11T12:30:19Zoai:ojs.revistaseletronicas.pucrs.br:article/6333Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T12:30:19Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
