Peripheral ameloblastoma: report of case and review of the literature.

A case of an extraosseous ameloblastoma occurring in a 33-year-old woman has been described. Of the 11 cases documented in the literature, only nine fulfill the histologic and clinical criteria for a true peripheral ameloblastoma. In contrast to the intraosseous ameloblastoma, the diagnosis of extramedullary or peripheral ameloblastoma implies a less aggressive neoplasm that can be treated by a more conservative surgical approach.
