cemento-ossifying fibroma is a fibro-osseous lesion that has benign neoplastic behavior. we report two cases of cemento-ossifying fibroma (cof) and review the literature in order to study the imaging findings of cof. it is almost unavoidable that diagnosis of fibrous dysplasia from cof will be complicated by the fact that some pathologic features are shared by both lesions. so the final definit...

Figure Legend: Figure 1 Bone Fibro-osseous lesion in the femur of a female B6C3F1/N mouse from a chronic study. Figure 2 Bone Fibro-osseous lesion in a female B6C3F1/N mouse from a chronic study. This fibro-osseous lesion shows replacement of bone by fibrovascular tissue. Figure 3 Bone Fibro-osseous lesion in a female B6C3F1/N mouse from a chronic study. Figure 4 Bone Fibroosseous lesion in a f...

We present a case of ethmoid mucocele occurring in a two-month-old child, and associated (presumably causally) with a benign fibroosseous lesion of the ethmoid bone. These two conditions may be more frequently associated than previously recognized; MR greatly facilitates their evaluation.

Cemento-ossifying fibroma (COF) of maxilla is comparatively rare lesion of the maxillofacial region. There is often a misdiagnosis in the category of fibroosseous lesions, owing to an overlap of clinical, histological and radiographic features amongst the separate entities. We present a case of giant maxillary COF causing extensive disfiguration of the face, along with extensive review of the c...

Focal cemento-osseous dysplasia (FCOD) is a benign fibroosseous condition that can be seen in dentulous and edentulous patients. It is an asymptomatic lesion and needs no treatment; however, follow-up is essential due to the possibility that it can progress to a condition called florid cemento-osseous dysplasia. Clinically, the lesion resembles periapical pathosis of odontogenic origin. FCOD is...

Ossifying fibroma of the jaw is a benign fibroosseous tumour. The growth of it is slowly and it is well circumscribed. Occurrence of multiple ossifying fibromas (synchronous) is rare in the jaw, and only a few cases have been documented. The most of these cases were in only maxilla. The fewer cases were reported in both of maxilla and mandible. We report a case of bilateral synchronous ossifyin...

Fibrous dysplasia is a benign fibroosseous lesion characterised by the replacement of normal bone by excessive proliferation of cellular fibrous connective tissue which is slowly replaced by bone, osteoid, or cementum-like material. It causes bone pain, deformities, and pathological fractures. Fibrous dysplasia (FD) is a sporadic benign skeletal disorder that can affect one bone (monostotic for...

Fibro-osseous lesions compose woven or immature bone formed by benign proliferation of spindle cells. Based on radiographic and histologic features, these lesions are grouped into many specifi c entities.[1] The overlapping histological and confusing nomenclature can be simplifi ed by their radiographic presentation. They are clearly defi ned by their pattern in plain radiograph or in computed ...

Oral manifestations of severe secondary hyperparathyroidism include maxillary and mandibular deformities, brown tumors, dental abnormalities, and metastatic calcification of soft tissues. We report on a chronic hemodialysis (HD) woman with severe, uncontrolled secondary hyperparathyroidism and a painful, nontender mass in the floor of her mouth. The most likely clinical diagnosis was a bone tum...
