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...

Juvenile ossifying fibroma (JOF) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. Two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (TrJOF) and a psammomatoid juvenile ossifying fibroma (PJOF). Psammomatoid variant is predominantly a craniofac...

Juvenile ossifying fibroma considered as a variant of ossifying fibroma by some authors is rare. Its aggressive behavior necessitates early detection and proper surgical management. It may mimic different pathologic entities of jaw at different stages. A case report of juvenile aggressive ossifying fibroma in a 12-year-old girl which was diagnosed, investigated and treated successfully is prese...

Cemento-ossifying fibroma is a lesion containing both fibrous and osseous components. Such lesions include fibrous dysplasia, ossifying fibroma, cemento-ossifying fibroma and cementifying fibroma. Periodontal membrane is the origin of fibro-osseous lesions other than fibrous dysplasia.Here a clinical case of a young woman referred for evaluation of a mass in the right side of face between eye a...

Fibro-osseous lesions of the face and paranasal sinuses are relatively uncommon. These lesions have overlapping clinical, radiologic and pathologic features causing difficulty in diagnosis. Neoplastic fibro-osseous paranasal sinus lesions can be benign or malignant. The benign fibro-osseous lesions described are: ossifying fibroma (and its histologic variants) and fibrous dysplasia. The variant...

Introduction Gingival growths are one of the most frequently encountered lesions in the oral cavity. Most of these lesions, such as irritational fibroma, pyogenic granuloma, peripheral ossifying fibroma and peripheral giant cell granuloma, are innocuous and rarely present with aggressive features. In majority of cases, these lesions are the result of trauma or chronic irritation. One of the inf...

Ossifying fibromas are benign fibro-osseous tumors of mesenchymal origin. Although ossifying fibromas have principally been found in the jaw, they have also been reported in the frontal, ethmoid, sphenoid, and temporal bones, as well as the orbit and anterior cranial fossa. Ossifying fibromas affecting the jaw exhibit variable behaviors ranging from slow growth to occasionally aggressive local ...

Ossifying fibroma is a benign fibro-osseous lesion of the jaw containing varying amounts of calcified deposits such as bone, cementum or both. This type of lesion is referred to as dysplastic or neoplastic in nature. In 2000, a 52-year-old male patient was referred to our clinic complaining of a giant swelling in the mandibular premolar-molar region. A histopathological diagnosis of ossifying f...

Ossifying fibroma is a benign neoplasm of the bone, usually involving the posterior tooth bearing area of the mandible, predominantly seen in females in 2nd-4th decade of life with 5:1 prediliction. Fibro-osseous lesions other than FD seem to arise from the periodontal membrane. These lesions are usually asymptomatic, well defined clinically and radiologically amenable for enucleation. Fibro-os...
