Ameloblastic Fibroma Mimicking Dentigerous Cyst: A Diagnostic Dilemma.

Ameloblastic fibroma is a rare, slow-growing odontogenic mixed tumor with neoplastic epithelial and ectomesenchymal tissue, which does not show inductive changes to form enamel and dentin. It is frequently found in the first two decades of life. It is often confused with ameloblastoma and dentigerous cyst due to the presence of an impacted tooth and can be distinguished histologically. Ameloblastic fibroma can be differentiated from ameloblastoma by the presence of myxoid appearance of connective tissue. A case of an 11-year-old female with a slow-growing swelling on the left side of mandible in the molar ramus region has been presented which was diagnosed as ameloblastic fibroma postenucleation.
