Hamartomatous Growth of Epithelial Derivatives. J Cancer Res Ther ;8: The identity of the ameloblastic fibroma has always been a source of debate where one school of oral pathologists considers it to be a hamartoma; as if the ameloblastic fibroma is allowed to progress or left undisturbed it may progress further to ameloblastic fibro-odontoma and then to odontoma while the other group of oral pathologist considers it hamqrtomas neoplastic because of its recurrence of the tumour Enzinger and Weiss’s Soft Tissue Tumors.

Nevertheless, the criteria to delineate hamartomas from other similar masses are ambiguous. Areas of cementum like masses formation with active cells entrapped, these cemental masses are surrounded by loose stroma X The odontogenic islands resemble ameloblastic islands which show peripheral arrangement of columnar to tall cuboidal cells.
The pathobiology of these lesions is sometimes understated. Fibrous dysplasia Fibrous dysplasia is a developmental tumour-like condition orap becomes relatively static after skeletal maturation. PMH shows hyperplasia of the myxomatous connective tissue resembles odontogenic ectomesenchymegiant cells and flecks of calcifications [9,10]. It commonly involves permanent first and second molars.
