Unicystic Ameloblastoma of The Mandible - A Case Report

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is the second most common odontogenicneoplasm, and only odontoma outnumbers it in reported frequency of occurrence. Its incidence, combined with itsclinical behavior, makes ameloblastoma the most significant odontogenic neoplasm. Unicysticameloblastoma (UA)refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histologicexamination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminaland/or mural tumor growth. It accounts for 5–15% of all intraosseousameloblastomas. We report a case ofunicysticameloblastoma in a 40-year-old male, and review the literature.
