Juvenile ossifying fibroma (JOF) is an expansive intraosseous lesion of the bones, comprising fibrous cell tissue that contains spheroid calcifications and randomly oriented mineralized structures. It is presented by patients under 15 years old. They are non-odontogenic lesions that imitate odontogenic lesions. The differential diagnosis is fibro-osseous lesions of the jaw, such as cemento-ossi...

Ossifying fibromyxoid tumor is a rare tumor of mesenchymal origin with varied presentation at different sites including head and neck. Clinically these are slow growing lesions and patients have a variable age at presentation. A 14 years old girl presented with a slowly enlarging gingival swelling, which on radiological examination showed increased rarefaction in the mandible with a provisional...

This is a case report of a reactive lesion which occurs only in the gingiva. This lesion is of a long duration causing erosion of the superficial bone. Histologically it is similar to other epulides of the gingiva but in addition contains ossified tissue. The lesion's confusing terminology is being discussed in view of its understanding to an American-trained or a British-trained surgeon. A rev...

Juvenile aggressive ossifying fibroma is a rare benign but locally aggressive tumor with high recurrent potentials. Juvenile aggressive ossifying fibroma poses diagnostic challenges because of its rapidly growing nature. A 7-years-old female child presented to the pediatric unit of our institution with a 9-month history of right maxillary tumor. An initial diagnosis of Burkitt's lymphoma was ma...

An ossifying soft-tissue lesion is potentially malignant. The possibility of malignancy increases in the absence of significant trauma. Pseudomalignant myositis ossificans can be easily confused with malignant lesions. A 22-year-old man presented with an ossifying mass in the adductor compartment of the thigh. The mass was excised and histopathologically reported as a soft-tissue osteosarcoma, ...

A 19-year-old man with refractory generalized epilepsy related to tuberous sclerosis complex (TSC) (figure 1) complained of chronic left facial swelling. Physical examination disclosed typical mucocutaneous findings of TSC (hypomelanotic macules, shagreen patch, ungual fibromas, facial angiofibromas) and a hardened well-limited mass in his left maxilla, evidenced as an odontogenic extensive lef...

BACKGROUND Ossifying fibroma is a rare benign bone tumor that occurs mostly in the jaw, but also affects paranasal sinuses and fronto-ethmoidal complex. Occipital bone is an extremely rare location for these tumors; only two cases have been reported. METHODS We present the first case reported as psammomatoid subtype of ossifying fibroma, according to the 2005 WHO classification. An 18 years o...

INTRODUCTION Juvenile ossifying fibromas are uncommon benign tumors. Their aggressiveness added to their high tendency to recur, provoke real diagnostic and therapeutic challenges for the dental practitioner and make a postoperative follow-up over the years indispensable. CASE REPORT In this report, we present a case of a seven-year-old girl presented with a swelling in the face at the upper ...

cone beam computed tomography is a useful technique for imaging the craniofacial lesions. it produces more realistic images that facilitate interpretation. juvenile ossifying fibroma (jof) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. mandibular lesions can be seen in 10% of the cases.in both jaws, it has a predilection for the...
