Fibroma, Ossifying

Ossifying fibromyxoid tumor is an uncommon neoplasm with uncertain histogenesis. This tumor is usually characterized by a small, painless mass in the subcutaneous tissue or limb muscles. In this case, an ossifying fibromyxoid tumor of the mandible was reported, and relevant literature was reviewed.

Ossifying fibroma is a neoplasm representing one of the benign fibro-osseous lesions of the jaw. ossifying fibroma has been designated as a demarcated,occasionally encapsulated lesion consisting of fibrous tissue that contains variable amounts of mineralized material resembling abnormal bone or cementum-like tissue. most of them are solitary and show slow, often expansile growth centrally within the jaws and characteristrically behave in a benign fashion. But, rarely they occur as a multiple and in a gigantic form exhibiting an aggressive nature. We has a case of multiple ossifying fibroma showing rapid-growing behavior and sequential occurrence in all four jaw quadrants resulting in severe facial deformity and orbital compression. therefore such a rare case is reported here.]]>

OBJECTIVES: To present a rare case of a large ossifying fibroma of the frontoethmoid sinus and describe our experience with the clinical presentation, diagnosis, management dilemmas, surgical approach and outcome of our patient.

METHODS:
Design: Case Report
Setting: Tertiary Government General Hospital
Patient: One

RESULTS: A 29-year-old housewife consulted with a large left frontoethmoidal mass of 20 years duration causing significant facial deformity, left eye proptosis, headache and psychosocial distress. Initial CT scans and MRI revealed a well-encapsulated mass occupying the frontoethmoid sinus, left orbit and anterior cranial fossa and subsequent surgical management involved three important aspects: 1) Wide extirpation of the tumor; 2) Preservation of the brain, left orbital contents and function; and 3) Reconstruction of the facial defect using calvarial bone graft, abdominal fat and temporalis muscle flaps.

CONCLUSION: A large ossifying fibroma of the frontoethmoidal sinus threatens the integrity of the vital structures it compresses and poses compelling diagnostic and surgical challenges. Adequate imaging, multidisciplinary planning and surgical expertise are needed to ensure a successful outcome.

ossifying fibroma is a true osteogenic neoplasm. It is also called as ossifying fibroma or cementifying fibroma. Small lesions seldom cause any symptoms and are detected only on radiographic examination. Large lesions result in a painless swelling of the involved bone. In radiographic features the lesion most often is well defined and unilocular. It may appear completely radiolucent, or more often varying degrees of radiopacity. It is composed of fibrous tissue that contains a variable mixture of bony trabeculae, cementum-like spherules, or both. Treatment of most lesions generally is enucleation of tumor. However, some lesions which have grown large and destroyed considerable bone, may necessitate surgical resection and bone grafting. This case was the bony lesion that was found by accident in patient with mandibular left body and subcondylar fracture. In radiographic examination, there was a mixed radiolucent and radiopaque lesion in mandibular left body area with fracture line. We treated on mandibular left body and subcondylar fracture and enucleated the lesion on the left body area simultaneously. At surgical exploration, the lesion was well demarcated from the surrounding bone, thus permitting relatively easy separation of the tumor from its bony bed. In histopathologic examination, the lesion contained bony trabeculae and cementum-like spherules within a background of cellular fibrous connective tissue. It finally diagnosed as cemento-ossifying fibroma from the result of biopsy.]]>

BACKGROUND: Juvenile ossifying fibroma (JOF) is defined as a variant of the ossifying fibroma, and the latter includes juvenile trabecular ossifying fibroma (JTOF) and juvenile psammomatoid ossifying fibroma (JPOF). JOF can be distinguished from other craniofacial fibroosseous lesions by its tendency to recur and its clinical mimicry of malignant bone tumors, but some clinical and histological features of JOF overlap with the other fibro-osseous lesions as well. We aimed to identify the clinicopathologic definition of JOF. METHODS: Forty-two cases of fibro-osseous lesions were reviewed and they were classified into JOF, fibrous dysplasia (FD) and ossifying fibroma (OF). RESULTS: JTOF had long, slender and anastomosing trabeculae of osteoid in a fibrocellular stroma, and JPOF had small ossicles resembling psammoma bodies with a thick collagenous rim in the fibrous stroma, which are features that differ from those of FD and OF. Radiologically, JOF and OF showed a well-defined lesion but FD exhibited an ill-defined lesion. Clinically, the average age of the JOF patients was the youngest, followed by OF and FD. For JOF, three cases had rapid growth and two others showed recurrences. JOF mainly occurred in the paranasal sinuses, OF in the mandible and FD in any craniofacial bone. CONCLUSION: We demonstrated the distinct characteristics of JOF and these features may be helpful for the diagnosis and management of this malady.

Cemento-ossifying fibroma is a rare benign tumor from periodontium, which usually occurs in mandible body and mandible ramus. It consists of collagen fibrils, fibroblast, and cementoblast. This article reported a case of giant cemento-ossifying fibroma and discussed the clinical features and treatment.
