Abstract
WHO Histological Typing of Odontogenic Tumors was revised in 1992, and a section of unicystic ameloblastoma was added.
A 37-years-old male had a cystic lesion in the premolar region of the mandible, and a 67-years-old male had a lesion suspected to be ameloblastoma in the molar region of the mandible. The radiographic findings showed unilocular and multilocular radiolucent lesion with a smooth margin, respectively. These lesions were treated by enucleation. Histopathological findings revealed that these lesions were type II and type I unicystic ameloblastomas, respcectively. There has been no recurrence in these cases.
Fourteen cases of unicystic ameloblastoma reported in literatures and these 2 cases were reviewed clinicopathologically.
