Aggressive atypical ameloblastic fibrodentinoma: Report of a case

Tooth bud attached to the follicle around the lesion was removed. Open in a separate window. Abundant small blood vessels surrounded the odontogenic epithelium Figure 2.

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 fibor with the presence of dentine and enamel. Relative frequency of central odontogenic tumors: Some pathologists consider them as separate entities.

The case presented here also showed an aggressive growth pattern and the histological study revealed few areas showing increased cellularity and cellular pleomorphism, raising a doubt toward the malignant transformation of the lesion. First, a gingival lesion is subject more than its intraosseous counterpart to constant irritation from plaque, calculus, food impaction, and low-grade trauma.

Computed tomography revealed a voluminous, space-occupying, expansile lesion at the posterior part of the right mandible.

Int J Surg Case Rep. Thus, the formation of AFO might be based on enamel matrix production, which is one of the most important features of the lesion.

She could not remember that her daughter had undergone any trauma. CD31 staining confirmed that there were abundant small blood vessels in the tumor stroma, especially in the area adjacent to the enamel epithelium Figure 4.

The age of our patients provides further evidence that contradicts this conclusion as our patient is an extremely young child.
