Multilocular ameloblastic fibro-odontoma. A case report in
the anterior maxilla


Randa Al-Fotawei, BDS, FDS RCS

Ameloblastic fibro-odontoma is a benign, slow growing, expansile epithelial odontogenic tumor with odontogenic mesenchyme. Although it was reported in the earlier literature that ameloblastic fibro-odontoma and odontoameloblastoma are identical lesions in 1968, World Health Organization (WHO) defined this tumors as two distinctly separate lesions. Clinically, this lesion is an expansile lesion which exhibited little tendency to infiltrate bone. The majority of these tumors were reported in younger patients (mean age 11.5). The maxilla and mandible appear to be equally affected. Altered occlusion and delay in eruption of teeth are the common features. A 10-year-old female patient presented to the Oral and Maxillofacial Surgery Clinic of the College of Dentistry, King Saud University, Riyadh with chief complaint of huge swelling on the right maxilla, with retained deciduous tooth # 52 and delayed eruption of the tooth # 12. Radiographic interpretation showed well-circumscribed, multilocular cavity in right maxillary bone and right maxillary sinus. Within the cavity are varied amounts of radiopaque material that represented the hard dental structures, and impacted tooth # 13 and # 14. Careful surgical curettage of the entire two lesions and capsular fragment was done. Histopathology report revealed that it is ameloblastic fibro-odontoma. The interesting finding of the present case compared to previous reported cases were the presence of two similar lesions in the same site. This report described a relatively rare odontogenic tumor in a young patient and it emphasizes the importance of including the lesion in the differential diagnosis of any expensile lesion accompanied with delay of eruption of teeth of young age patient.
