In some studies, the term AFO represents a histological combination of ameloblastic fibroma and complex odontoma [ 1216 ]. If there is a recurrence accompanied by a change of the histological pattern toward a more unorganized fibrous stroma with displacement of the epithelial component, then more extensive treatment procedures appear to be indicated [ 19 ]. Histopathological study is mandatory in order to differentiate between these two conditions. Lesion in left side odpntoma the mandible.

However, malignant transformation into ameloblastic fibrosarcoma was reported by Howell and Burkes. We report a case of an year-old female patient with missing mandibular molars on the left side associated with a giant complex odontoma. Determination of a case-dependent treatment plan may provide an optimum outcome.

The lesions are usually diagnosed during the first and second decades of life [ 4 — 6 ]. Radiographically, it appears as a well-circumscribed, expansile radiolucency that generally oodontoma solitary or multiple small radiopaque foci. The table compares Gorlin’s amelonlastic composed of his own case plus those cases reported in the earlier literature which he thought belonged in this diagnostic category with Hooker’s survey 26 cases. Gorlin syndrome, also known as nevoid basal cell carcinoma syndrome, is associated with basal cell carcinomas, odontogenic keratocysts and fibromas ovarian and heart.
