Ameloblastic fibroma: A case report.

Ameloblastic fibroma is a rare mixed odontogenic benign tumor that can occur in either mandible or maxilla but mostly it is found in posterior region of mandible. It can present either peripherally or centrally with a majority of the cases predominantly occurring in first two decades of life and mostly affects male patients. It is characterized by epithelial islands and cords submerged in ectomesenchyme that bear resemblance to the dental papilla and enamel organ but without actual hard tissue formation. Ameloblastic fibroma is a rare odontogenic tumor consisting of neoplastic epithelial and mesenchymal tissues. Recent reports have suggested that this lesion has the potential for high recurrence (18%) and greater chances of recurrent Ameloblastic fibroma transforming into Ameloblastic fibrosarcoma (45%). A 34-year-old male patient presented with pain and swelling in right mandibular posterior region. Intraorally expansion of buccal cortical plate with tenderness over swelling was present. Extraoral examination revealed facial asymmetry on right side. In view of imaging and clinical findings, provisional diagnosis of Odontogenic Keratocyst or Recurrent Ameloblastoma was considered. After obtaining informed consent and general systemic evaluation, the lesion was enucleated under general anesthesia and biopsied which confirmed the diagnosis of Ameloblastic fibroma. Ameloblastic fibroma is a mixed odontogenic tumor composed of odontogenic ectomesenchyme resembling dental papilla with epithelial strands and nests similar to the dental lamina and enamel organ, but with no dental hard tissue formation.
