Aggressive atypical ameloblastic fibrodentinoma: Report of a case

Abstract

Ameloblastic fibroma and related lesions constitute a group of lesions, which range in biologic behaviour from true neoplasms to hamartomas. This group of lesions is also sometimes referred to as mixed odontogenic tumors and usually includes ameloblastic fibroma, ameloblastic fibrodentinoma and ameloblastic fibro-odontoma. Despite numerous efforts however, there is still considerable confusion concerning the nature and interrelationship of these mixed odontogenic tumors and related lesions. The malignant counterpart of these lesions namely aameloblastic fibrosarcoma, ameloblastic dentinosarcoma and ameloblastic odontosarcoma respectively are said to arise secondarily in their benign counterpart or de novo. Recurrence of the benign lesion raises the risk towards malignant transformation therefore a radical surgery should be planned inspite of enucleation or curettage. Here we present a case of an aggressive ameloblastic fibrodentinoma which was radically excised in the light of clinical and histological presentation followed by reconstruction of mandible.
