An ameloblastic fibroma is a fibroma of the ameloblastic tissue, that is, an odontogenic tumor arising from the enamel organ or dental lamina. It may be either. Ameloblastic fibroma, is a mixed odontogenic tumor, which commonly affects young children under the age of 20 years, with the mandibular premolar-molar. ameloblastic fibroma in a 9-year-old boy has been presented along with a review of the literature. The tumor responded to conservative surgical treatment.

An analysis of the interrelationship of the mixed odontogenic tumors: National Center for Biotechnology InformationU. The overlying mucosa was intact. Ameloblastic fibroma, jaw tumors, Ki, odontogenic tumors. Thin septa were observed within lesion. The epithelial component is characterized by the proliferation of islands, strings or projections of odontogenic epithelium and a peripheral layer of cuboid or columnar cells with central areas resembling the stellate reticulum of the dental organ 14.
Complex epithelial Warthin’s tumor Thymoma Bartholin gland carcinoma. On palpation, the swelling was slightly tender and no abnormality was ameloblasttic in the adjacent teeth. Photomicrograph showing tall columnar ameloblasts with reversal of polarity. Well-defined unilocular radiolucency prohibiting the eruption of the left maxillary second molar.

Despite the radiopaque foci, no hard tissues were observed at microscopical analysis. Ameloblastic fibroma AF is a benign tumor of mixed odontogenic origin, which affects predominantly young individuals. Ameloblastic fibroma in one-year-old girl.

Ameloblastic fibroma in six-year-old male: Larger nests may show a central area of stellate reticulum.
Despite the asymptomatic ribroma of AF amelpblastic appear as an unilocular radiolucency 4the present case was characterized as multilocular mixed image. Incidence of Maxillary AF is believed to be uncommon by itself; its bilateral presentation is exceedingly rare.
Ameloblastic fibroma is a rare odontogenic tumor comprising neoplastic epithelial and mesenchymal tissues. In contrast to conventional wmeloblastic, the strands of AFs show double or triple layer of cuboidal cells. The mesenchymal component contained evenly distributed plump ovoid and stellate cells in a loose myxoid to ameloblasstic eosinophilic matrix, resembling the primitive dental papilla.
It may be either ameloblaastic neoplastic or merely hamartomatous an odontoma. Although few cases have been reported, the majority of studies indicate a slight predilection for the male gender 2 – 4. You can help Wikipedia by expanding it. None, Conflict of Interest: Computed tomography with 3D reconstruction was performed which revealed a hyperdense mass involving the labial and buccal cortex and extending up to the pterygoid plates. Ameloblastic fibromas AFs are a rare variety of benign odontogenic tumors composed of proliferating odontogenic epithelium embedded in a cellular ectomesenchymal tissue resembling dental papilla [ 1 ].
World Health Organization Classification amleoblastic Tumours: Microscopically, hematoxylin and eosin sections showed islands and strands of epithelial cells in a loose connective tissue stroma resembling primitive dental papilla [ Figure 1 ]. Ameloblastoma, odontogenic myxoma, keratocystic odontogenic tumor and central giant cell lesion should be considered in the differential diagnosis 39.

Side profile of the patient showing the extensions Click here to view. The lesion probably induced a peripheral bone neo-formation, resulting in a mixed radiographic image. No atypia was observed.

A case report with a follow-up of 4 years. Ameloblastic fibroma, differential diagnosis, incidental finding, mixed image, radiographic features. As it is difficult to differentiate a hamartomatous lesion from a neoplasm based merely on histology, age of the patient should be an important consideration while deciding the treatment plan.
Numerous mitotic cells or any atypical mitotic figure if noticed suggests a malignant entity such as ameloblastic fibrosarcoma AFS in the differential diagnosis [ 1415 ].
