ntroduction: Odontogenic fibromas (OFs) were defined in the latest classification of the World Health Organization (WHO) as a uncommon neoplasm characterized by an erratic quantity of inactive odontogenic epithelium in a rather-mature fibrous stroma. [1] OF is considered to be an " Elusive and controversial tumor " due to its rarity and the uncertainty. [2] It is a benign neoplasm, representing...

THE CONCEPT OF FIBROOSSEOUS LESIONS OF BONE HAS EVOLVED OVER THE LAST SEVERAL DECADES AND NOW INCLUDES TWO MAJOR ENTITIES: fibrous dysplasia and ossifying fibroma. Peripheral cemento-ossifying fibroma is a relatively rare tumour classified between fibroosseous lesions. It predominantly affects adolescents and young adults, with peak prevalence between 10 and 19 yrs. The cemento-ossifying fibrom...

BACKGROUND Giant cell fibroma is a type of fibrous tumour of the oral mucosa which rarely affects children under the age of 10. The purpose of this paper was to contribute two clinically and histologically documented cases of giant cell fibroma in the free gingiva of a 7 and 6 year old boys. METHODS Both nodules were presented in the mandibular anterior region. In the differential diagnosis s...

The central odontogenic fibroma (COF) is a benign odontogenic tumor of mesenchymal tissue such as the periodontal ligament, dental papilla or dental follicle. It is an extremely rare tumor, accounting less than five percent of all odontogenic tumors. In this report, we describe the case of an eight year old girl who presented with a painless swelling of the left mandible. Radiographic evaluatio...

Handlers and his colleagus described Central Odontogenic Fibroma (COF) in 1991, as an extremely rare benign odontogenic tumor that is derived from dental mesenchymal tissue. Its accounts for about 0.1% of all odontogenic tumors. COF is an asymptomatic, slow growing lesion, usually occuring in adults and has a female predilection. This article presents a case of COF in a 35-year-old male, on the...

Central odontogenic fibroma (COF) represents a rare group of benign odontogenic tumor, while dentigerous cyst (DC), on the other hand, is the odontogenic cyst that encloses the crown of an unerupted tooth. A combination of COF and DC is rare and not reported in literature till date. The aim of this paper is to report a case of COF occurring concurrently with DC. The simultaneous occurrence of C...

Cemento-Ossifying fibromas are rare fibro-osseous lesions that affect the jaw bones and are included in the group of mesodermal odontogenic tumours. Clinically, it is a large asymptomatic tumor of aggressive appearance. Four separate categories have been identified: Periapical cemental dysplasia, benign cementoblastoma, cementifying fibroma and a rare gigantiform variety. It has been suggested ...

Calcifying odontogenic cyst (COC), Central odontogenic fibroma (COF) and aggressive central giant cell granuloma (CGCG) are rare pathologic diseases affecting the jaws. While the Co-existence of two of them is reported in the literature, existence of all three conditions in one patient is an extremely rare entity. In the present report, initial biopsy revealed fibrosarcoma, therefore mandibular...

Central cementifying fibroma is a rare non odontogenic tumor coming in the group of fibro osseous lesion, arising from periodontal ligament and is usually seen in tooth bearing area. It can affect both the mandible and the maxilla, particularly the mandible. This bone tumour consists of highly cellular, fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum o...
