As it is a noninvasive tumor, recurrence is very rare. Helical computed tomography images showing an expansile, well-circumscribed lesion containing a calcified mass compatible with odontogenic tissue a axial cuts; b coronal cuts.
She had radiographic examinations, including panoramic, helical, and cone-beam computed tomography.
Ameloblastic Fibro-Odontoma: A Diagnostic Challenge
The tumor was excised with 0. Postoperative antibiotics and analgesics were given for 1 week. The medical, social and family histories were unremarkable, as were the results of a review of systems and a physical examination. The patients understand that their names and initials will not be published and due efforts will be made to conceal their identity, but anonymity cannot be guaranteed. The arrangement of the soft tissues and the development stage of the involved tooth amloblastic useful criteria for diagnosis [ 3 ].
Photomicrograph stained with H and E reveals the presence of dense fibrous tissue and a few odontogenic epithelial cell islands. Sign in to make a comment Sign in to your personal account.
Board review question 1. The diagnosis was ameloblastic fibro-odontoma, which is a rare mixed odontogenic tumor, derived from epithelial and ectomesenchymal elements that form the dental tissues. International Journal of Dentistry.
An year-old female presented to our unit with the complaint of a painless swelling on the left side of the lower jaw for the last 3 years that seemed to show a progressive increase in size.
Ameloblastic fibroodontoma or complex odontoma: Two faces of the same coin
Case report critically analysed. Declaration of patient consent The authors certify that they have obtained all appropriate patient consent forms. In the present case, the patient presented to our department with previous examinations, including panoramic, helical and cone-beam computed tomography.
Long-term follow up with short intervals should be maintained in the management of AFO. View at Google Scholar L. Sign in to customize your interests Sign in to your personal account. Abstract An year-old girl presented to our department to have a second opinion regarding a lesion involving her left mandible.

The diagnosis of complex odontoma was made. Odkntoma microscopic examination of sections stained with hematoxylin and eosin revealed strands and islands of odontogenic epithelium showing peripheral palisading and loosely arranged central cells, identical to stellate reticulum, embedded in a myxoid cell-rich stroma resembling the dental papilla Figure 4.
An impacted odonntoma is also visible.
However, the concept that these lesions represent a continuum of differentiation is not widely accepted, with other researchers suggesting that they are separate pathologic entities [ 12 — 15 ].
The clinical examination did not display any sign of pain or swelling in the left mandible. This appearance suggests that the lesion is a ameloblqstic odontoma.
Cahn and Blum [ 13 ] postulated that ameloblastic fibroma the histologically least differentiated tumor develops first into a moderately differentiated form, following AFO and eventually into a complex odontoma.
View at Google Scholar N. The reconstruction of the defect was done with nonvascularized corticocancellous iliac crest bone, which was taken from the contralateral side [ Figure 6 ]. Conflicts of interest There are no conflicts of interest.

AFO is a benign tumor that exhibits odonttoma same benign biologic behavior as that of ameloblastic fibroma, showing inductive changes that lead to the formation of both dentin and enamel [ 1 ].
After reflection of the periosteal layer, the expanded buccal cortex was seen. In our case, the permanent left mandibular molars were missing. According to the revised World Health Organization WHO classification [ 10 ], ameloblastic fibroma and AFO are believed to be stages of complex odontoma formation [ 1 ].

Gardner syndrome, a variant of familial adenomatous polyposis FAPis an autosomal dominant disease characterized by GI polyps, multiple osteomas, skin and soft tissue tumors such as epidermal inclusion cysts and desmoid tumors.
To our surprise, histopathological examination revealed the tumoras an AFO [ Figure 7 ]. Supernumerary teeth Complete well formed teeth Usually in males Can rarely be associated with ameeloblastic such as cleidocranial dysostosis General: In some studies, the term AFO represents a histological combination of ameloblastic fibroma and complex odontoma [ 1216 ]. Oral inspection revealed good oral hygiene. Slootweg reviewed 50 cases with this condition, for which the mean age was 8.
