Abstract
Objective. This study aimed to add to existing knowledge on 90 cases of desmoplastic ameloblastoma (DA) previously
reported in the scientific literature and analyze data that could help speculate on its biologic profile.
Study design. From 330 cases of ameloblastoma (pooled from 573 histologically diagnosed odontogenic tumours) 17
cases of DA were retrieved and analyzed for estimated mean growth rate (EMGR) and histologic variants. EMGR for
DA was compared with EMGR for conventional ameloblastoma (CA), as recorded over the same period of 38 years.
Results. Desmoplastic ameloblastoma had predilection for mandible (81.2%), posterior mandible being the most
commonly affected, contrary to scientific literature reports of anterior maxillary predilection. Simple DA (88.0%) and
DA with osteoplasia (12.0%) were the histologic variants observed. EMGR for DA (0.36 0.44 cm/mo) was
significantly less than EMGR (0.71 1.16 cm/mo) for CA (P .000480).
Conclusion. This study speculates that DA tends to be less biologically aggressive than CA and has predilection for
posterior mandible in Nigerians
