“…Radiographically is usually a well-defined unilocular radiolucent lesion (4,14,20) , although less frequent, the multilocular aspect has been reported (5,17) . UA is classified histologically into groups, luminal, intraluminal and mural.…”

“…The definitive treatment of ameloblastoma is surgical and it is usually a safe resection, with the possibility of removing soft tissue. However, the extent of surgical intervention and the adoption of conservative or radical measures remains controversial (4) . The management of ameloblastoma represents a challenge for surgeons, because it requires not only adequate resection, but also functional and aesthetic reconstruction of the residual defect (21) .…”

“…Radical treatment is characterized by mandibulectomy or segmental resection of the lesion with safety margins (4,5) . This form of treatment is associated with low recurrence of the lesion, however it can cause numerous complications, such as facial deformities, dysfunctions, and psychological changes (4,22) .…”

“…Clinically it can be classified into 3 types, solid or multicystic, unicystic and peripheral. The solid type generally presents greater local aggressiveness, which differs from the unicist variant (4,5) . About 80% of all ameloblastomas are located in the mandible, mainly in the molar region (6,7) .…”

Ameloblastoma is a benign neoplasm, originated from the odontogenic epithelium. It preferentially affects the mandible and due to its infiltrative growth pattern, it has a tendency to local recurrence. Treatment varies based on clinical, histological and radiographic characteristics. The aggressive treatment, such as marginal resection, has shown good results, however, it also has greater morbidity. Conservative treatments, such as decompression, enucleation and curettage, can also be used, with specific indications, and when carefully performed, it has a good prognosis. Thus, the objective of this work is to describe a case of mandibular ameloblastoma, treated in a more conservative way. Male patient, 53 years old, presented an increase in volume in the anterior region of the mandible. The clinical and radiographic characteristics suggested that it was a cystic lesion, so decompression and incisional biopsy were performed, the diagnosis of which was cystic ameloblastoma. The decompression device was maintained until bone neoformation was no longer observed, with conservative marginal resection being performed, followed by peripheral ostectomy.

“…Este caso em específico relata a ocorrência de um ameloblastoma unicístico, o qual se difere do ameloblastoma multicístico por ser menos agressivo e apresentar melhor comportamento clínico (12,13). No geral, dos casos de ameloblastoma, 5 a 15% são unicísticos, po mural demonstra um comportamento mais agressivo, devendo ser tratado de forma mais ampla (15).…”

O ameloblastoma é um tumor odontogênico benigno de origem epitelial, localmente invasivo, de curso lento e que apresenta consideráveis taxas de recidivas. É considerado o tumor odontogênico benigno mais relevante clinicamente, sendo atualmente classificado como "ameloblastoma", "ameloblastoma unicístico", "ameloblastoma periférico ou extraósseo" e "ameloblastoma metastatizante". A variante unicística é a segunda mais prevalente, respondendo por aproximadamente 15% de todos os ameloblastomas, mostrando características singulares especialmente em pacientes mais jovens. Este trabalho tem por finalidade aclarar as características desta variante do ameloblastoma a par tir do relato de caso do atendimento de um paciente adulto jovem acometido pelo tumor na mandíbula, abordando os aspectos clínicos, imaginológicos, histopatológicos, terapêuticos e prognósticos envolvidos. Neste caso clínico, o tratamento de escolha para o ameloblastoma unicístico foi, inicialmente, a marsupialização da lesão e posteriormente a enucleação com ostectomia periférica e exodontia dos dentes envolvidos. Esta opção de tratamento demonstrou bons resultados, diminuindo os danos ao paciente quando bem indicada, para isso é essencial um diagnóstico precoce e asser tivo associando características clínicas e histopatológicas. O paciente segue em proservação cautelosa, visto que o padrão de proliferação do tipo mural requer uma maior atenção dada a sua maior possibilidade de recidiva.
