Aggressive atypical ameloblastic fibrodentinoma: Report of a case

Abstract Ameloblastic fibroma and related lesions constitute a group of lesions, which range in biologic behaviour from true neoplasms to hamartomas. 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. Case report A year-old girl was referred to oral and maxillofacial surgery department with an incidental radiological finding of radiopaque mass in the posterior region of maxilla.

The flap was repositioned in the same position and suturing was done with vicryl 3. AFO can be differentiated from AF by the radiological appearance as well as through histological evaluation. Ameloblastic fibrodentinoma involving anterior maxilla: In some of the cases previously diagnosed as AFD, dentine matrix or dentinoid tissue is an area of hyalinization around the epithelial component, and some workers have suggested that hyalinized material may not represent dentine formation. 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.

The immature variant is histologically composed of strands and cords of odontogenic epithelium without an enamel organ-like structure.

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.

There was no recurrence after the 1-year follow-up. Ameloblastic fibro-dentinoma, ameloblastic fibroma, ameloblastic fibro-odontoma, dentinoma, odontogenic tumors. AFD has predominantly occurred in the posterior region of the jaw and, especially, the mandibular posterior region.

The second variant is a hamartomatous non-neoplastic lesion that amepoblastic to be able to differentiate into an ameloblastic fibroodontoma and mature further into a complex odontoma. The dentist decided to refer the child to our hospital.

Then the tooth-like substance spontaneously exfoliated. Hematoxylin and eosin staining for the gingival lesion. Because this lesion clinically resembles other nonneoplastic lesions and is very rare in gingiva, establishing a correct diagnosis is achieved only based on specific histological characteristics.

One ajeloblastic them clearly exhibits enamel organ differentiation.

National Center for Biotechnology InformationU. Contemp Clin Dent ; 3: Suvy Manuel in data analysis and Dr. The two main complaints associated with AFO are swelling and failure of tooth eruption. This article has been cited by other articles in PMC.

The age of our patients provides further evidence that contradicts this conclusion as our patient is an extremely young child. While in some dentnoma cases, hyalinised area containing entrapped cells has been considered as an abortive dentine or dentinoid tissue because of its proximity to the odontogenic epithelial.
