JOF, also known as psammomatoid or juvenile active (aggressive) ossifying fibroma, is a benign fibro-osseous tumor made of highly cellular fibrous connective tissue Juvenile trabecular ossifying fibroma Cellular fibrous stroma composed of spindled to stellate fibroblastic cells with bands of osteoid without osteoblastic rimming together with immature bony trabeculae surrounded by plump osteoblasts Trabeculae can show an anastomosing or lattice pattern Mitoses can be present but without cytologic atypi
Ossifying fibromas are well-demarcated benign fibro-osseous tumors of craniofacial skeleton most often in the jaws. It has two types, conventional and juvenile ossifying fibroma (JOF). JOF is considered a separate entity from ossifying fibroma due to its locally aggressive behavior and tendency to o Ossifying fibromas are normally slow growing benign lesions. Radiographically they can present as radiolucent, mixed or radiopaque lesions depending on the degree of maturity. A period of at least 6 years is required for the lesion to pass from the radiolucent to radiopaque stage Radiology of Juvenile ossifying fibroma, Adnan Rashid, MD 1.

In the 2005 WHO histological classification of odontogenic tumors, this tumor is referred to as ossifying fibroma but in this article, the term cemento-ossifying tumor is used to differentiate from peripherally occurring ossifying fibromas..

Although the cell of origin for OFs is unknown, the OFs may derivefrom elements present in the periodontal ligament space (26, 28). Sawyer JR et al found a balanced translocation with recurring breakpoints at Xq26 and 2q33 in patients affected with OF (29)

Ossifying fibroma is a benign, locally aggressive bone-forming tumor of young children, most commonly seen under age 10 years (juvenile ossifying fibroma). These tumors belong to the spectrum of fibroosseous lesions, which range from nonossifying fibromas (fibrous cortical defect) to fibrous dysplasia Juvenile ossifying fibroma (JOF) is an uncommon fibro-osseous lesion occurring in the facial bones. It is highly aggressive and has a strong tendency to recur. It has been recognized as a separate histopathological entity among the fibro-osseous group of lesions.

Both entities are rare in comparison to conventional ossifying fi-broma and are indistinguishable on imaging. Therefore, clin-ical, radiologic, and pathologic correlations are required to reach the correct diagnosis A clinical, radiographic, histologic and follow up study of 18 cases of ossifying fibroma involving the mandible and maxilla was performed.

Juvenile ossifying fibroma (JOF) is a group of heterogeneous, benign fibro-osseous tumors of the craniofacial skeleton in young people. According to the WHO, it may present as one of two histologic variants: juvenile psammomatoid ossifying fibroma (JPOF) and juvenile trabecular ossifying fibroma (JTOF) Introduction. Juvenile ossifying fibroma (JOF) is defined as a fibro-osseous lesion that is characterized by cell rich fibrous tissues, bands of cellular osteoid trabeculae and giant cells (1-3).It presents in children younger than 15 years of age, behaves aggressively, and tends to recur (2,3).It is a variant of ossifying fibroma and also known as aggressive, active or. Juvenile variant of ossifying fibroma may be mistaken for malignancy, particularly osteosarcoma. Radiology is central to their diagnosis because of the very limited nature of the tumour. Microscopically, the lack of cytologic atypia or abnormal mitosis, and the presence of bone maturation or cementum deposits are consistent with an ossifying. Juvenile aggressive ossifying fibroma /prosthodontic course 1. www.indiandentalacademy.com 2. INTRODUCTION (Active juvenile ossifying fibroma, juvenile aggressive cemento-ossifying fibroma ) The juvenile ossifying fibroma is a unique lesion that has been distinguished from the larger group of ossifying fibroma on the basis of age of patient ,most common site of involvement and clinical.
Juvenile aggressive ossifying fibroma (JAOF) is a rare variant of ossifying fibroma. Conventional ossifying fibromas are slow growing neoplasms thought to originate from osseous mesenchyme, commonly arising in the mandible. Conversely, JAOF occurs more frequently in the paranasal bones with rapid growth leading to local destruction, facial asymmetry, nasal obstruction, and proptosis Juvenile ossifying fibroma (JOF) is a benign, bone-forming neoplasm occurring primarily in children and adolescents. JOF is an aggressive variant of ossifying fibroma of the jaw with a variable clinical behavior and a high tendency for recurrence. Early detection and prompt treatment are required to treat JOF successfully. This case report describes JOF in a 13-year-old girl presenting with a.

Cementifying fibroma is considered as a benign, osseous tumour, which arises from the periodontal ligament and is composed of varying amounts of cementum, bone and fibrous tissue. It is very closely related to other fibro-osseous lesions like fibrous dysplasia, cemental periapical dysplasia and other calcifying odontogenic cysts and tumour. We report a case of this entity along with. Cemento-ossifying fibroma (COF) is a benign tumor classified under fibro-osseous lesions characterized by the proliferation of fibrous tissue associated with the presence of osteoid or cementicle-like masses. COF of bony origin is highly neoplastic in nature compared to their soft tissue counterparts which are relatively rare. The authors here present a case report of COF arising from the left.

Juvenile psammomatoid ossifying fibroma (JPOF) is a fibroosseous tumor that arises in the craniofacial bones in young people. This lesion usually originates in the jaw, orbit, and ethmoid complex but can also be associated with the skull base and calvaria. Diagnosis must be made based on observing typical radiological and histopathological. Ossifying fibroma is a benign bone tumor, considered to be a type of fibro-osseous lesion. Its origin is supposed to be from periodontal membrane. 1 Most common site of occurrence for ossifying fibromas is the posterior region of the mandible. 2‒4 It may also occur in the maxilla, usually in the area of the canine fossa and in the region of the zygomatic arch with the most common occurrence. Ossifying fibromas include cementifying fibromas, cemento-ossifying fibromas and juvenile ossifying fibromas. Psammomatoid and trabecular types of juveline ossifying fibromas are recognized. 9 Dysplastic conditions around the teeth, Jaw lesions are fairly common in radiology practice. Familiarizing oneself with different conditions and. We report a rare case of cemento-ossifying fibroma in a 45-year-old man involving the body of the mandible and extending into the para-pharyngeal and infratemporal region.

She had a 5-year history of a slowly growing tumor, which at presentation was 15 cm in diameter and had resulted in left craniofacial deformity as well as left visual impairment. Due to the large tumor, the surgical resection plan necessitated a cranio-facial neurosurgical approach in. . It may occur in 35% of all children. It is not cancer. NOF is benign, which means it is just a collection of abnormal cells that stays where it is and does not move to other parts of the body. These fibromas occur more in males than in females, and are usually only found because. A non-ossifying fibroma is a benign (non-cancerous), non-aggressive tumor that consists mainly of fibrous tissue. It usually occurs in the thighbone or shinbone but may also occur in the upper extremities. A non-ossifying fibroma usually produces no symptoms. It usually resolves by itself. It never spreads Cardiac Fibromas. On CT, cardiac fibromas are homogeneous soft-tissue masses that are usually sharply marginated, but also can be infiltrative. Dystrophic calcification is common.; Chondromyxoid Fibroma. On computed tomography (CT), mild cortical expansion may be observed, and the lesions have a density greater than fluid throughout.; CT scans also exhibit characteristic lack of mineralization.
