Odontoameloblastoma, also known as ameloblastic odontoma, has a more aggressive behavior, similar to an ameloblastoma rather than an odontoma [ 9 ]. Fibrous tissue is of a primitive type containing spindle-shaped fibroblasts, some areas of hyalinization signifying dentin formation, and some clear spaces of enamel formation.
This website is intended for pathologists and laboratory personnel, who understand that medical information is imperfect and must be interpreted using reasonable medical judgment. In the present case, the patient presented to our department with previous examinations, including panoramic, helical and cone-beam computed tomography.
The patient underwent enucleation of the lesion and careful curettage of the surgical cavity under general anesthesia. The diagnosis of complex odontoma was made. The patient was kept under regular follow-up for 6 months and, to add to our delight, there were nosigns of graft failure or loco regional recurrence. We report a case of an year-old female patient with missing mandibular molars on the left side associated with a giant complex odontoma. The clinical features are painless swelling of the jaw, an asymmetrical face, missing permanent teeth, and displaced or impacted tooth.
I ntroduction Ameloblastic fibroodontomas AFOs are slow-growing, benign tumors developing from the odontogenic epithelium and ectomesenchyme. Gorlin syndrome, also known as nevoid basal cell carcinoma syndrome, is associated with basal cell carcinomas, odontogenic keratocysts and fibromas ovarian and heart.
In our case, the permanent left mandibular molars were missing. 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 amelobastic epidermal inclusion cysts and desmoid tumors. The mixed odontogenic tumours. Despite numerous efforts, however, there is still considerable confusion concerning the nature of these lesions [ 17 ]. Light 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.
Orthopantomogram oeontoma large, well-defined radiopaque lesion with focal radiolucent areas occupying the whole left body of the mandible. Cohen DM, Bhattacharyya I. C xmeloblastic R eport 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.

With the help odntoma a chisel and mallet, the outer cortical bone overlying the tumor was then removed.
There was buccal cortical expansion with an obliterated vestibular area.

Orphanet J Rare Dis ;1: Images hosted on other servers: After odontima of the periosteal layer, the expanded buccal cortex was seen. Histopathological study revealed it as an AFO, to our surprise. Radiographically, it appears as a well-circumscribed, expansile odonfoma that generally contains solitary or multiple small radiopaque foci.
Helical computed tomography images showing an expansile, well-circumscribed lesion containing a calcified mass compatible with odontogenic tissue a axial cuts; b coronal cuts. De Pedro Marina, and L.
Ameloblastic fibroodontoma or complex odontoma: Two faces of the same coin
She had radiographic examinations, including panoramic, helical, and cone-beam computed tomography. On histopathological examination, it was diagnosed as an AFO. Table of Contents Alerts. Frequently associated with an unerupted tooth Usually detected on routine radiographs Most commonly located between roots of erupted teeth or impeding the eruption of tooth Well marginated from surrounding bone May have a thin radiolucent region surrounding opaque mass Radiopaque matrix same density as components of adjacent teeth Early stage odontoma may have little calcified matrix, expanding the radiographic differential diagnosis Can occur as a component of combined odontogenic tumor, most commonly Calcifying cystic odontogenic tumor CCOT Multiple odontomas may occur as a component amekoblastic Case report critically analysed.
It occurs oontoma equal frequency in the maxilla and the mandible and with equal frequency in males and females [ odontoms ]. More disorganized or haphazard arrangement of pulpal tissues, enamel or dentin.
Declaration of patient consent The authors certify that they have obtained ameloblasti appropriate patient consent forms. An ameloblastic fibroodontoma AFO is a rare odontogenic tumor of mixed dental tissue origin.

The connective tissue is moderately cellular, with spindle-shaped fibroblasts. Photomicrograph stained with H and E reveals the presence of dense fibrous tissue and a few odontogenic epithelial cell islands.

Subdivided into compound odontoma and complex odontoma The most common odontogenic tumor Can obstruct the path of erupting teeth Most recent WHO Classification of Head and Neck Tumours regards majority of ameloblastic fibro-odontomas as developing odontomas rather than a distinct tumor IARC: Determination of a case-dependent treatment plan may provide an optimum outcome.
Radiography shows a well-defined, radiolucent area containing various amounts of radiopaque material of irregular size and amelohlastic [ 45 ]. Intraoral photograph showing missing ameloblatsic left mandibular molars and a calcified, toothlike structure protruding from the alveolar mucosa over the retromolar region. Treatment included surgical excision of the tumor followed by reconstruction with iliac crest graft.
