“…Recurrence rates range from 0% to 15%. A survey of the literature indicates that radical resection is the best treatment approach (Kreppel & Zoller, ). The most appropriate treatment for AM‐BC, based on all available treatments, has not been definitively established, because very few cases of AM‐BC have been reported; moreover, a valid statistical analysis to predict the prognosis or success of different treatment modalities has not been performed (Reichart, Philipsen, & Sonner, ; Ueda & Kaneda, ).…”

Objectives: To investigate the clinical features, pathologic manifestations, and biologic behaviors of a variant of ameloblastoma with basal cell features (AM-BC). Materials and methods: Following retrospective review of the clinical and pathological data of six cases of AM-BC, we described their histological and immunohistochemical (IHC) features and discussed the biologic behaviors, prognoses, pathogenesis, and clinical relevance of AM-BC. Direct sequencing of polymerase chain reaction products was also performed in all cases. Results: The six cases of AM-BC involved four women and two men, aged 22-82 years. Four lesions occurred in the maxilla and two in the mandible. Histologically, the basal cells tended to be arranged as unequally sized follicles, strands, or cords of odontogenic epithelium in the connective tissue stroma. Little or no stellate reticulum was present in the central portion of the nest. Expression of CKs was consistent with other histological variants of ameloblastoma (AM), but AM-BC had significantly higher p53 and Ki-67 (p < 0.05) labeling indices than other histological variants of AM. Two patients had BRAF gene mutations.

“…Similar to ameloblastoma (Effiom, Ogundana, Akinshipo, & Akintoye, ; Kreppel & Zöller, ), CEOT has a predilection for the mandible, with a proportion of at least 1.4:1, and most lesions develop in the posterior region, with tooth association in almost 50% of cases (Chrcanovic & Gomez, ). Our data concur with findings of previous case series of CEOT, which have demonstrated that more than 65% of cases occur in the mandible (Abrams & Howell, ; Ai‐Ru, Zhen, & Jian, ; Azevedo et al., ; Chen et al., ; Franklin & Hindle, ; Krolls & Pindborg, ; Vap, Dahlin, & Turlington, ).…”

“…É a neoplasia odontogênica mais comum. Podem surgir dos restos da lâmina dentária, de um órgão do esmalte, do epitélio de cistos odontogênicos ou das células basais da mucosa oral [1][2][3] . Esta patologia não possui marcada predileção por raça ou gênero, e costuma acometer mais adultos jovens, entre a segunda e quarta décadas de vida [1][2][3][4] .…”

Introdução: O ameloblastoma é um tumor benigno, localmente invasivo, originário do epitélio odontogênico e é a neoplasia odontogênica mais comum. Apresentam crescimento lento e sua ocorrência na maxila é pouco frequente. Objetivo: Discutir os métodos de tratamento para os ameloblastomas em maxila e demonstrar a utilidade da osteotomia Le Fort I na abordagem destas lesões. Material e Método: Estudo descritivo de relato de caso. Resultados: Observou-se a erradicação da lesão com uma abordagem de baixa morbidade e que permitiu bom resultado estético e funcional. Conclusão: A ressecção é o método mais indicado para tratamento dos ameloblastomas sólidos, e a sua realização utilizando a osteotomia Le Fort I podem trazer vantagens tanto no trans quanto no pós-operatório.Descritores: Ameloblastoma; Maxila; Osteotomia de Le Fort.ReferênciasKreppel M, Zöller J.
