Cemento-ossifying fibromas are benign tumors, and, although cases of an aggressive type have been reported, no cases of cemento-ossifying fibroma transforming into osteosarcoma have been documented previously. Low-grade osteosarcoma is a rare type of primary bone tumor, representing 1%-2% of all osteosarcomas. A 45-year-old female patient was diagnosed with cemento-ossifying fibroma, treated wi...

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...

Maxillofacial fibro-osseous lesions are a generic designation of a group of jaw disorders characterized by the replacement of bone by a connective tissue matrix, which displays varying degrees of mineralization in the form of woven bone or of cementum-like structures indistinguishable from “cementicles”.1 These lesions are of particular interest to the maxillofacial radiologist because they emp...

Cemento-ossifying fibroma is a mesodermal, slow-growing, benign fibro-osseous lesion of the jaws. A case of mandibular molar enlargement that was treated previously by other surgeons and diagnosed as cemento-ossifying fibroma, is presented. Two recurrences occurred 4 and 8 years after surgery due to incomplete surgical removal.

Ossifying fibroma of the vertebra is a very rare condition. We report a 16-year-old boy with ossifying fibroma of the third lumbar vertebra. Neurological and laboratory examinations demonstrated normal findings. Low-back pain, in the absence of radicular pain, was the presenting symptom. Plain radiography and computerized tomography scanning revealed an osteolytic lesion. The tumor in the third...

Ossifying fibromyxoid tumor (OFMT) is a rare soft tissue tumor of unknown histogenesis. OFMT is a recently described, mesenchymal neoplasm originally defined as a borderline or low-grade malignant lesion. It consists of chains and trabeculae of ovoid cells swimming in a fibromyxoid stroma [1,2]. OFMT combines the clinical course of both peripheral and central ossifying fibromas. Like POF, it is...

INTRODUCTION Juvenile ossifying fibroma is a rare, benign fibro-osseous tumour. In the light of a clinical case, the authors review the diagnosis, treatment and histological classification of these tumours. CASE REPORT A seven-year-old child presented with a naso-orbito-ethmoidal trabecular juvenile ossifying fibroma. Complete surgical resection via a transfacial approach was performed after ...

The peripheral cement-ossifying fibroma is a reactive gingival overgrowth occurring mostly in the maxillary anterior region in young adults predominantly affecting women, with greater prevalence at 28 years. It originates from the cells of the periodontal ligament. The final diagnosis is established by histological examination, which reveals the presence of cellular connective tissue with focal...

Large, atypical peripheral ossifying fibromas are known as giant peripheral ossifying fibromas.  These lesions have often been associated with heterogeneous clinical and radiographic characteristics subsequently leading to their misdiagnosis.  Biopsies have been the gold standard for the diagnosis of such lesions.  This study reports on an acute presentation of giant peripheral ossifying fibrom...

INTRODUCTION Lipomas are derived from the mesodermal germ layer and are frequently encountered in adults, and account for almost 50% of all soft tissue tumors. Lipomas are classified based on their component tissues and location. A rare subtype, ossifying parosteal lipoma, accounts for 0.3% of all lipomas and occurs with intimate association with the underlying periosteum of the adjacent bone. ...
