Abstract

Objective: to report a case of unicystic ameloblastoma in the anterior region of the mandible, describing the diagnostic methods used and the treatment applied. Case report: a 40-year-old female patient attended the Oral and Maxillofacial Surgery and Traumatology Service of the School of Dentistry at the Federal University of Bahia, Brazil, complaining of increased volume in the anterior region of the mandible, with a 10-month evolution. Imaging tests revealed extensive unilocular lesion that expanded the cortical bone in the mental region. Excisional biopsy of the lesion was performed under general anesthesia. The examination of the specimen obtained confirmed the diagnosis of unicystic ameloblastoma, for which it was decided to maintain the initial therapy. The patient is still being followed-up by the team, with no signs of relapses. Final considerations: the management of unicystic ameloblastoma sometimes requires excisional biopsy of the lesion to differentiate it from odontogenic cysts and isolate its histological pattern. The conservative approach may be adopted if along with strict monitoring.
