Abstract :
Unicystic ameloblastoma is believed to be less aggressive and responds more favourably to conservative surgery than the solid or multicystic ameloblastomas. This report is a rare case of unicystic ameloblastoma of the maxilla that was treated by enucleation under suspicion of a dentigerous cyst related to impacted premolar. The neoplastic nature of the lesion became evident only when the enucleated material was available for histologic examination. With this report, the authors illustrate the importance and complexity of a differential diagnosis of lesions with a cystic aspect in the anterior region of the maxilla, among them — inflammatory radicular cysts, odontogenic keratocysts, dentigerous cysts, adenomatoid odontogenic tumor and_ unicystic ameloblastoma. Relevant diagnostic problems and choice of treatment of unicystic ameloblastoma are presented along with a review of the literature.
