Central odontogenic fibroma of simple type: An original observation

Central odontogenic fibroma is an uncommon, benign, slow-growing intraosseous mesenchymal odontogenic tumour. It presents a diagnostic dilemma to the clinician and the pathologist because its clinical and radiological features resemble other odontogenic and/or non-odontogenic tumours, and the differential diagnosis is based on histological examination. In this report, we describe our experience with a case of a 23-year-old female patient with central odontogenic fibroma of the mandible that was diagnosed as 'simple type'. Highlighting a subtype that was dropped from the last World Health Organization classification of head and neck tumours is important to accumulate more information about this lesion and to show its different features. Despite its rarity, central odontogenic fibroma should be included in the differential diagnosis of intrabony tumours of the jaws. These findings can better educate oral and maxillofacial surgeons about the unusual nature of this lesion, help establish a correct diagnosis and give the appropriate therapeutic management.
