The recurrence rate of intraosseous AFO is uncommon: Conservative excision of the tumor is the treatment of choice. Although the mechanism of malignant transformation of AF and other related benign mixed odontogenic tumors remain unsettled, multiple surgical denntinoma of recurrent lesions remain one of the important factors in their malignant transformation.

Then the tooth-like substance spontaneously exfoliated. Ameloblastic fibrodentinoma AFD is a rare tumor and is considered as a histological variant of AF showing inductive changes that lead to the formation of dentin.

Majority of the articles state that the associated tooth bud has to be removed in order to avoid recurrence. World Health Organization classification of tumours; pp. Sporadic recurrences of AFO have been attributed to the inadequate surgical removal at the time of initial treatment.

It is also distinguishable from ameloblastic fibro-dentinoma not only because it shows dental structures resembling dentine, but also because it contains enamel-like tissues.

Therefore, in place of planning a conservative treatment, a radical resection should be performed especially if the lesion is aggressive and presents with erosion and perforation of the cortical plate. The most striking finding was the presence of increased cellularity with mild pleomorphism of the dental papilla-like cells in few areas [ Figure 5 ]. The secretion of amelogenins is associated with the induction of enamel and dentinoid in an ameloblastic fibro-odontoma.

Footnotes Source of Support: Kannan Venugopal were responsible for the manuscript preparation. Adequate clinical and radiological investigations, proper surgical excison, accurate histopathological diagnosis, and long term follow up will ensure the right treatment plan for the patient. This article has been cited by. Tooth bud attached to the follicle around the lesion was removed. Dentinoma has been defined as a very rare odontogenic neoplasm composed of odontogenic epithelium and immature connective tissue and characterized by the formation of dysplastic dentin.

Aggressive atypical ameloblastic fibrodentinoma: Report of a case

Owing to the formation of dentine, whether a primitive osteodentin or the very rare mature tubular type of dentine, the tumor appears as a mixed radioopaque and radiolucent lesion with well-defined borders. Most of these benign lesions on complete excision heal well, but they need long-term follow-up.

Fobro tomography revealed a voluminous, space-occupying, expansile lesion at the posterior part of the right mandible. The malignant counterparts of AF, AFD and AFO are ameloblastic fibrosarcoma, ameloblastic fibrodentinosarcoma and ameloblastic fibroodontosarcoma, respectively.

Minute calcifications were evident within the lesion [ Figure 3 ]. Their clinical manifestations resemble much those of localized reactive gingival lesions [ 4 — 6 ]. The immature variant is histologically composed of strands and cords of odontogenic epithelium without an enamel organ-like structure. J Oral Pathol Med.

Oral panoramic radiograph showed a radiopaque mass with a radiolucent border in the right posterior maxilla covering almost the whole right maxillary tuberosity Fig. The ameloblastic fibro-odontoma AFO ameloblastiv a rare benign odontogenic lesion defined as a tumour with the general features of ameloblastic fibroma but dentinooma also contains enamel and dentine.

Conflict of interest None declared. Hard tissue examination exhibited conglomerate mass of enamel and dentine arranged in a disorganized pattern and in close relationship to the ameloblastic epithelium Fig. Abstract Ameloblastic fibroma and related lesions constitute a group of lesions, which range in biologic behaviour from true neoplasms to hamartomas.

Ameloblastic fibrodentinoma and ameloblastic fibro-odontoma: Some of dentinima stromal cells, leukocytes, and endothelial cells were also positive for CD44 staining. Ameloblastic fibro-odontoma is defined by the World Health Organization as a neoplasm consisting of odontogenic ectomesenchyme resembling the dental papilla, epithelial strands and nest resembling dental lamina and enamel organ conjunction with the presence of dentine and enamel.
