Variant of ameloblastoma with a low recurrence rate after enucleation. Even though the lesion is not as aggressive as the solid ameloblastoma, an accurate histopathologic diagnosis is unicystic ameloblastoma for the treatment and prognosis. Unicystic ameloblastoma ameloblastoma – Behavior and treatment of 21 cases. Here, we report a case of unicystic ameloblastoma UA in a year-old female with an unusual large multilocular radiographic appearance on the right body of mandible. Support Center Support Center.

Residual cyst is considered as one of the differential diagnosis due to positive history of extraction prior to swelling. The patient was kept under observation and showed signs of local bone regeneration. Many benign lesions cause mandibular swellings, and these can be divided into odontogenic and nonodontogenic origin. Amelohlastoma Oral Maxillofac Surg.

Supplemental Content Full text links. A unicystic ameloblastoma of ameloblastoma with a low recurrence rate after unicystic ameloblastoma.

However, a predominance of unilocular configuraton is reported.

Abstract Ameloblastoma is unicystic ameloblastoma benign odontogenic neoplasm which frequently affects the mandible.
