Adenoid Ameloblastoma with Dentinoid

Abstract

Ameloblastoma and adenomatoid odontogenic tumors are the most common odontogenic neoplasms. However, hybrid variant of the two lesions, Adenoid Ameloblastoma with dentinoid is extremely rare. The lesion comprises of characteristic histopathological features of Ameloblastoma and Adenomatoid odontogenic tumor and also shares certain clinical characteristics with either of the entities. Adenoid Ameloblastoma with dentinoid may be considered at the more aggressive end of spectrum of benign odontogenic neoplasms. Owing to the frequent tendency of lesion to be underdiagnosed, careful histopathological screening of submitted biopsies is warranted. With the increase in number of reported cases in the recent years, it is likely to be included as a separate entity in the upcoming WHO classification. The present systematic review aims at collectively presenting the demographic, clinical, radiographic and histopathological features, treatment performed along with its outcome for all the cases of Adenoid Ameloblastoma with dentinoid reported in scientific literature till date.
