INTRODUCTION AND OBJECTIVES The central odontogenic fibroma (COF) is a benign odontogenic tumour derived from the dental mesenchymal tissues. It is a rare tumour and only 70 cases of it have been published. Bearing in mind the rareness of the tumour, 8 new cases of central odontogenic fibroma have been found by analyzing the clinical, radiological and histopathological characteristics of COF. ...

in 1991, handlers and colleagues described the central odontogenic fibroma (cof) as a distinct entity which is a rare benign odontogenic tumour and up to the present, only 78 cases of it have been published. cof usually occurs in an adult patient and has a predilection for the anterior region of the jaws. a 2.8:1 female to mail ratio is typically noted. this article presents a case of cof in a ...

Intra-osseous fibromas of the jaw are classified by origin. Intra-osseous odontogenic fibromas have odontogenic epithelia, while desmoplastic fibromas do not. However, it is often difficult to determine the odontogenic origin for central fibromas. Three subjects with a diagnosis of intra-osseous fibroma were examined. Case 1 was a 35-year-old man found to have a panoramic radiograph from the ri...

UNLABELLED Central odontogenic fibroma (COF) is a rare benign odontogenic tumor derived from the dental ectomesenchymal tissues. A 16-year-old Caucasian female patient was referred by her dentist for a radiolucent asymptomatic area associated with the crown of the impacted lower right third molar. A preliminary diagnosis of a follicular cyst was supposed. The lesion was surgically removed under...

Odontogenic tumors mainly occur as intraosseous growths but sometimes may present in a peripheral location on the gingiva where they are referred to as peripheral odontogenic tumors (POTs) which are a rare entity, the most common of them being the peripheral odontogenic fibroma that is an otherwise uncommon, slowly growing, benign odontogenic neoplasm of the periodontal soft tissues. In fact, p...

OBJECTIVE To perform a comparative study of the cellular proliferation in the peripheral and central fibromas. MATERIAL AND METHODS Immunohistochemistry for PCNA and the AgNOR technique were performed in 9 cases of peripheral odontogenic fibroma (POF), in 4 cases of odontogenic fibroma (OdF), in 8 cases of peripheral ossifying fibroma (PEOF) and 7 cases of ossifying fibroma (OsF). The Kruskal...

A 16-years-old female patient with painless swelling of the right side of mandible is described. She noticed the swelling from two years ago, without painful symptoms. Axial CT imaging showed buccal expansion with intact buccal and lingual cortical bone. The report of incisional biopsy was central odontogenic fibroma. Under general anesthesia the lesion was removed after ostectomy of buccal cor...

Central odontogenic fibroma (COF) is a rare tumor that accounts for 0.1% of all odontogenic tumors. It has been defined as a benign neoplasm, which appears in the jaw. Clinically, the lesion grows slowly and leads to cortical expansion. Radiologically, the most common finding is multilocular radiolucency. In some cases, it may be associated with root resorption or displacement. Histologically, ...

Although rare, hard tissue deposits, namely dystrophic calcifications and cartilage, have been reported to occur in the connective tissue wall of the odontogenic keratocyst. However, dentinoid formation has not been previously documented. A case involving the left mandibular premolar-molar region in a 37-year-old Malay male is described here along with a brief review on the reported prevalence ...
