Large ameloblastic fibro-odontoma in a 7-year-old girl with analysis of 108 cases

View Article: PubMed Central - PubMed

ABSTRACT

Background:: Odontogenic tumors such as ameloblastic fibro-odontoma (AFO) are rare conditions in children and are often asymptomatic. AFOs are found by routine clinical and radiological examination or when they cause obvious intra- or extra-oral swelling.

Materials and methods:: A case of an AFO in a 7-year-old girl is described, and 107 cases from the literature and this report are analyzed.

Results:: The total of 108 cases revealed the average age at presentation of AFO to be 6.3 years in boys and 9.6 years in girls. There was a slight male predilection and AFO lesions most often occurred in the posterior mandible. AFO was almost always associated with an unerupted tooth or teeth.

Conclusions:: While the recurrence rate of AFO was found to be 5.5%, long-term postoperative clinical and radiological follow-up is advised to ensure no future signs of aggressive recurrence.

Figure 4: Preoperative cone-beam computed tomography scan revealing large mixed lesion of he left ramus and body of mandible

Mentions: An otherwise healthy 7-year-old girl was referred by her dentist because of swelling of the left side of the mandible. An asymmetric facial swelling was obvious on extraoral examination [Figure 1]. There was no history of trauma or local infection. Intraoral examination revealed normal mucosa overlying the lesion and the absence of the left mandibular first and second molar teeth [Figure 2]. A distinctive hard bulge was palpable in the vestibule of the left mandible molar region. The mouth opening was normal and there was no pain or other symptoms apart from the swelling. Panoramic radiography [Figure 3] and cone-beam computed tomography scan [Figures 4 and 5] both revealed a large well-defined radiolucent area that contained several radiopaque structures of varying sizes and shapes. The lesion extended from the first molar to the coronoid process and the condylar neck. The borders of the lesion were well circumscribed and the lesion had displaced the developing second molar tooth bud down to the inferior border of the mandible.
