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.

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.

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 ].
