Adenoid variant of peripheral ameloblastoma with cellular atypia in the retromolar pad area: A case report

Adenoid ameloblastoma (AA) is a very rare subtype of solid/multicystic ameloblastoma. It demonstrates areas of typical or atypical adenomatoid odontogenic tumor along with the ameloblastic content. To date, there are 17 reported cases of AA. This paper reports, however, the first introduced adenoid variant in a peripheral ameloblastoma. It also depicts an unusual appreciation of cellular atypia and nuclear pleomorphism. This find may promote a new pathogenetic scenario to the current nosology of this debatable lesion and to the WHO taxonomy of benign ameloblastomas in 2005
