Abstract :
Desmoplastic ameloblastoma (DA) is an epithelial odontogenic tumor, a rare variant of ameloblastoma. It was first described by Eversole in 1984. In the World Health Organization Classification of odontogenic tumors (2005), desmoplastic ameloblastoma has been considered as a distinct entity from conventional/multicystic ameloblastoma. DA differs strikingly in its clinical, radiological and histopathological presentation when compared to other variants of ameloblastoma. Herewith, we report an unusual case of DA in a 30 year old female patient involving anterior mandible with detailed clinical history, an unusual radiographic picture & histopathological presentation showing osseous tissue formation with areas of cystic change. Also review of literature and possible explanation of etiopathogenesis of osseous tissue formation & cystic change in DA will be discussed.
