Tratamento conservador de ameloblastoma unicístico com proliferação mural em paciente jovem Relato de caso

Abstract

Ameloblastoma is a odontogenic epithelial origin tumor with the most common clinical significance. Although being considered a benign tumor, clinically it has a slow, but aggressive growth, proliferating in an invasive way in the adjacent tissues with a great potential of recurrence. Unicystic ameloblastoma is considered a distinct variant because of its clinical and radiographic characteristics similar to other cystic lesions and less aggressive behavior. It presents three types of histological patterns: Luminal, intraluminal and mural. Due to its characteristics the therapeutic approach of ameloblastoma is still controversial being classified as radical or conservative, each with its advantages and disadvantages. In choosing the surgical approach, several factors must be taken into account such as location, extent, histopathological characteristics, age and others. This study aimed at showing a case of a conservative approach of a unicystic ameloblastoma with mural proliferation in a young patient. The patient complained about a volumetric increase in face and posterior region of jaw. Clinical, radiographic and histopathological exams confirmed the diagnosis of unicystic ameloblastoma. The patient was submitted to marsupialization and later enucleation associated with the peripheral osteotomy and subsequent treatment of the wound bed with Carnoy's solution. The patient remains under clinical and radiographic follow-up for the observation of bone formation and to verify if there was a resolution of the lesion with the treatment performed
