Ameloblastic fibroodontoma is a benign mixed odontogenic neoplasm considered in patients with asymptomatic swelling and unerupted teeth that exhibit histologic features between ameloblastic fibroma and complex odontoma. Radiographically, this lesion appears as radiolucency admixed with focal radio opaque masses of irregular shapes and sizes. This lesion is confirmed by the presence of proliferating odontogenic epithelium, ectomesenchyme, and dental hard tissue formation on pathological analysis supplementing clinical and radiographic findings...

A 24-year-old womanpresented with ameloblastic fibrosarcoma arising from ameloblastic fibroma. The delayed presentation accounted for the extensive destruction of the mandible and complete occlusion of her oral cavity. This resulted in an inability to eat and maintain oral hygiene. A multidisciplinary team management approach involved nutritional optimisation, segmental mandibulectomy, reconstruction with a reconstructive plate and a free anterolateral thigh flap to line the the floor of mouth. Functional and aesthetic outcome was acceptable, and the patient is planned for secondary free fibular flap bony reconstruction...

Ameloblastic fibrodentinoma is a benign odontogenic tumor belonging to the category of "odontogenic epithelium with odontogenic ectomesenchyme" along with recognition of induction in the form of dentin in atypical or dysplastic forms. The biological behaviour of ameloblastic fibrodentinoma is not very different from ameloblastic fibroma; hence, it is treated similarly by conservative procedures. It is important to understand the histopathogenesis of these rare tumors. Though rare, they are an independent entity awaiting recognition...

The latest (4th) edition of the World Health Organization Classification of Head and Neck tumours has recently been published with a number of significant changes across all tumour sites. In particular, there has been a major attempt to simplify classifications and to use defining criteria which can be used globally in all situations, avoiding wherever possible the use of complex molecular techniques which may not be affordable or widely available. This review summarises the changes in Chapter 8: Odontogenic and maxillofacial bone lesions...

Primordial odontogenic tumor (POT) is a rare lesion in the jaw which has been included as a new entity of benign mixed epithelial and mesenchymal odontogenic tumour in the latest World Health Organization (WHO) classification (2017). Only seven cases have been reported. It typically occurs in the posterior mandible. We report an additional case of POT in the maxilla of an 8-year-old girl presenting with an asymptomatic buccal enlargement. A well-defined, unilocular, radiolucent lesion was observed radiographically...

Ameloblastic fibroma (AF) is an uncommon true mixed odontogenic tumor, with a relative frequency between 1.5% and 4.5% of all odontogenic tumors. It may behave either as a true neoplasm or as a hamartomatous proliferation of odontogenic epithelium of the enamel organ and odontogenic mesenchyme of the primitive dental pulp. Frequently diagnosed between the first and second decades of life with 75% of cases was diagnosed before the age of 20 and present with a well-defined unilocular or multilocular radiolucencies...

BACKGROUND: Expression of various cellular/molecular factors change during the course of tumor formation from odontogenic tissues of the tooth germ. Evaluation of these factors can help provide a better perception of the tumorigenesis and biologic behavior of odontogenic tumors (OTs). Syndecan-1 is a heparan sulfate proteoglycan which has not been extensively investigated in these lesions. The objective of the present study was to assess the immunohistochemical expression of CD138 in adenomatoid odontogenic tumor (AOT), ameloblastic fibroma (AF) and odontogenic myxoma (OM) and to compare it with ameloblastoma and keratocystic odontogenic tumor (KCOT)...

Ameloblastic fibroma is a rare mixed odontogenic tumor mostly occurring in the posterior region of the mandible. The peripheral variant is very rare and to the best of our knowledge, only three cases have been reported in the English literature. In this report, we describe a case of peripheral ameloblastic fibroma in a 54-year-old woman with two years of follow-up.

BACKGROUND: Ameloblastic fibrosarcoma (AFS) is a rare odontogenic neoplasm of the jaw that usually arises de novo or through a malignant change in the mesenchymal component of a preexisting or recurrent benign fibroma. The majority of AFS cases reported in the literature arise in the mandible. CASE REPORT: A 35-year-old male presented with an asymptomatic left maxillary mass that on imaging was found to be effacing most of his maxillary sinus. He underwent a left maxillectomy with free-flap reconstruction and adjuvant radiotherapy to the tumor bed...

Transformation of an ameloblastic fibroma to an ameloblastic fibrosarcoma has been reported rarely in the literature. The present case report describes such evolution in a patient under long-term follow-up. The patient was first treated in 2008, and he developed the malignant counterpart of the disease 2 years later. The patient is currently under careful long-term follow-up and is free of disease. This article describes the clinical and radiographic features, histological characteristics, immunohistochemical findings, and surgical treatment of the tumor...

Fourier transform infrared (FTIR) microspectroscopy is considered a useful tool in the biomedical field, for analysing in situ and at cellular level, very small areas of tissues and cells, with minimal sample preparation and without the use of stains or probes. This spectroscopic technique has been successfully applied to analyse biological samples from patients affected by tumoral pathologies, with particular attention to oral cavity lesions. In this study, we describe the application of FTIR microspectroscopy to characterize and discriminate the most recurrent benign and malignant diseases of oral cavity compartment...

Ameloblastic fibroma (AF) is rare benign odontogenic tumour which usually occurs in the first two decades of life. It can occur either the mandible or maxilla but it is most frequently found in the posterior region of the mandible. Treatment of AF in usual is a conservative approach, such as enucleation and curettage but the aggressive lesions require a radical approach. A more radical approach should be considered in older patients who have likely high recurrence tendency. This report describes a case of AF in a 38-year-old female patient identified during a routine radiographic exam...

Ameloblastic fibrodentinoma (AFD) is a debatable neoplasm with respect to its clinical, biological and histopathological diagnosis. The clinical and radiological presentation may mimic ameloblastic fibro odontoma, odontoma, ameloblastic fibroma and cemento-ossifying fibroma. We report an interesting case of AFD occurring in canine region of mandible in a one-year-old infant. From a review of English language literature, to the best of our knowledge this is the first case occurring in an infant. The purpose of this case report is to create awareness among the clinicians to make the best possible management of this controversial pathologic entity...

Calcifying cystic odontogenic tumour (CCOT) is a relatively rare lesion of oral and maxillofacial region and forms only 2% of all odontogenic tumours. It was previously known as Calcifying odontogenic cyst and only recently has been classified as a tumour by WHO. The controversy regarding its origin can be owed to its diverse clinical and histopathological presentation and variation in reported malignant potential. It was first reported by Gorlin in 1962 and since then conundrum regarding its true nature has persisted...
