title: Ameloblastic fibroma and its sarcomatous transformation.
abstract: A case of ameloblastic fibroma, and one of its more aggressive variety, the ameloblastic "fibrosarcoma", are presented. The clinical and morphologic differences are discussed. In our opinion, ameloblastic "fibrosarcoma" is a semimalignant tumor. Therefore we propose "proliferating ameloblastic fibroma" as a more appropriate designation.
