odontoameloblastoma
21 May 2008Odontoameloblastomas are extremely rare oral tumors. For the cases that have been described, they happen to occur in the mandible of young patients.
In contrast to AF, they are destructive lesions on radiographs and have calcifying components.
Histologically, these tumors have ameloblastomatous component as wlee as odontoma-like components.
Biologically, they tend to behave like ameloblastoma and characterized by multiple recurrence and local aggression.

Histogenesis
Because they lack the typical cytogenetic abnormalities seen in ordinary lipomas, some have speculated that they may actually be of vascular origin but with an (...) -
