A benign, occasionally aggressive tumour of young adults affecting the posterior jaw, which is characterised by a prominent ameloblastoma-like epithelial component.

Imaging
Unilocular or multilocular; well-circumscribed, corticated border; mixed radiolucency/radio-opacity.
 
Management
Simple curettage; recurrences are rare.

In follicular ameloblastomas and ameloblastic fibro-odontoma cases there was focal reactivity to [alpha]SMA around the blood vessels (figure 1 & 2).
In the present study, expression of positive [alpha]SMA immunoreactivity was restricted around the blood vessels in follicular ameloblastomas and ameloblastic fibro-odontoma cases due to the presence of pericytes.

In the present case, the ameloblastic fibro-odontoma are composed of primitive enamel and dentin structure with abundant fibroblast with intermixed stellate cells is in agreement with earlier work (Mahjour and Pear Craft, 2007).
It includes ameloblastoma, odontogenic myxoma, adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor (Pindborg tumor), calcifying odontogenic cyst (Gorlin cyst), ameloblastic fibroma, ameloblastic fibro-odontoma, compound odontoma, and complex odontoma.
