Ameloblastic fibro-odontoma. Case report and review of the literature.

Ameloblastic fibro-odontoma (AFO) is defined by the World Health Organization (WHO) as a neoplasm composed of proliferating odontogenic epithelium. It is a benign, slow-growing, expansive tumour that clinically appears as a well-encapsulated, benign lesion. Histologically, AFO has been classified as an ameloblastic fibroma or odontoma. Despite numerous efforts, however, there is still considerable confusion concerning the nature, the histology and the therapy of these lesions. This paper reports an additional case of a large AFO and reviews the relevant literature regarding the clinical and pathologic features of this lesion.
