The author observed and compared the radiographic features of 49 cases of the fibrous dysplasia and 14 cases of the ossifying fibroma in the osteoblastic or mature stage radiologically and histopathologically. The obtained results were as follows: 1. Fibrous dysplasia occurred most frequently in the 2nd decade, but ossifying fibroma in the 3rd and 4th decades, and both lesions occurred with slight predilection in females. 2. In most cases, chief complaints were painless facial swelling. And 61.1％ of fibrous dysplasia occurred in the maxilla, 92.9％ of ossifying fibroma in the mandible, and most of these lesions occurred in the premolar-molar region. 3. In the mandibular lesions, ossifying fibroma was shown more oval and round shape. but fibrous dysplasia was shown fusiform shape. 4. Fibrous dysplasia was shown homogeneously distributed. complete radiopaque shadow at 63％, and ossifying fibroma was shown concentric. mixed appearance of radiolucent and radiopaque shadow at 92.9％. 5. Fibrous dysplasia was entirely shown poorly outlined and blended to normal surrounding bone, but ossifying fibroma was shown well-defined border. 6. Cortical thinning and expansion were observed in these lesions. but degree of cortical expansion was more severe in ossifying fibroma than fibrous dysplasia. 7. Loss of lamina dura. tooth displacement. and displacement of mandibular canal were observed in both lesions. but root resorption was observed in ossifying fibroma only.

Central odontogenic fibroma is a rare odontogenic neoplasm that originates from odontogenic ectomesenchyme. Here, a case of central odontogenic fibroma in a 17-year-old male is reported. Since the present case showed a multilocular radiolucency with partially ill-defined border between the right mandibular condyle and the distal root of the right mandibular third molar, differential diagnosis involved a wide range of pathosis from benign lesions like ameoloblastic fibroma and odontogenic myxoma to more aggressive lesions such as desmoplastic fibroma, juvenile aggressive fibromatosis, or fibrosarcoma.

Ossifying fibroma is a rare benign tumor of the maxilla and the mandible. And its nosology and diagnosis have had many problems. It occurs more common in young adult, especially in female, and there is a predilection for the mandible. The lesion is generally asymptomatic and recurrence is rare after conservative excision. Among ossifying fibroma, juvenile active ossifying fibroma grows rapidly, produces many symptoms, and frequently recurs after conservative excision. Authers experienced a case of juvenile active ossifying fibroma which recurred after two times of conservative surgery, and report is with review of the literatures.

Sclerotic fibroma is a rare fibrous tumor of the skin associated with Cowden's disease. In 1989, Rapini described sclerotic fibroma without Cowden's disease as solitary sclerotic fibroma of the skin. It is a solid, well-circumscribed, slow-growing nodular tumor and it looks similar to a keloid scar. Consequently, it is extremely difficult to make a differential diagnosis of solitary sclerotic fibroma with keloid scar based on clinical findings only. The authors report a case of solitary sclerotic fibroma arising at the left lateral thigh of a 25-year-old man.

The peripheral odontogenic fibroma (WHO type) is a relatively rare and characteristically benign and unencapsulated, exophytic gingival mass of fibrous connective. Odontogenic epithelium is found within the gingival mass, but usually appears to playa minor role when compared to the fibrous component. The connective tissue is ranged from markedly cellular to relatively acellular and well collagenized. but the connective tissue in this case report appears less cellular. Peripheral odontogenic fibroma must be differentiated histologically from peripheral ossifying fibroma, Peripheral cemental epithelial odontogenic tumor and Peripheral ameloblastoma. The author reports the following conclusions after clinical and radiological examination, excisional biopsy and reviewing literatures. 1. Peripheral odontogenic fibroma is rare lesion and frequently occurs in interdental papila as a form of fibroblastic connective tissue including odontogenic epithelium within the lesion. 2. Peripheral odontogenic fibroma must be differentially diagnosed with Peripheral ossifying fibroma by including less cellular connective tissue, odontogenic epithelium and dysplastic dentin 3. Treatment consists of surgical excision including removal of alveolar bone which is eroded under the lesion

Cementifying fibroma is an odontogenic tumor of periodontal ligament origin, consisting of a proliferation of fibrous tissue that forms cementum. Cemento-ossifying fibroma, cementifying fibroma and ossifying fibroma are difficult to distinguish on clinical and radiographic exmination, and on histopathology. However, when the calcified product is represented by ovoid or curvilinear deposits, the lesion is often referred to as cementifying fibroma. Cementifying fibromas of the jaws are well-circumscribed, generally slow-growing lesions. Although most lesions appear to be limited to the tooth-bearing areas, a few have extended into the angle-ramus area or encroached on the maxillary sinus. Radiographically, the cementifying fibroma could present as a radiolucent, radiopaque or mixed density lesion, depending on the degree of maturity. We have observed two cases of cementifying fibroma occurred in the left maxillary premolar-molar area of 38-year-old woman and 35-year old man. We obtained that two cases were shown the followed results; 1. Clinically, main clinical symptom was facial swelling and pain at palpation 2. Radiographically, well-circumscribed radiolucent lesion and radiolucent lesion with radiopaqu e foci were seen on the left maxillary premolar-molar areas. Loss of lamina dura and root resorption or divergency were also seen. 3. Histopathologically, many cementum-like calcifications were observed in the hypercellular connective tissue.

Ossifying fibroma is a rare, benign, fibro-osseous tumor of mesenchymal origin. It develops mainly in the mandible, where it is usually slow growing and asymptomatic, whereas in the maxilla and paranasal sinus, it is more aggressive. The vast majority are located in the posterior region of the mandible; however, ossifying fibroma involving the maxillary sinus is uncommon. It may reach a very large size and cause facial asymmetry. It shows a female predilection, and most cases are seen in the third and fourth decades of life. Radiographically, ossifying fibroma is radiolucent or radiopaque depending on the amount of calcification. Histologically, the tumor consists of a cementum-like or bony mass. Ossifying fibroma shares many histopathologic features with fibrous dysplasia. Their radiographic features may help to separate these entities when pathological differentiation is uncertain. It is important to differentiate ossifying fibroma from fibrous dysplasia. The treatment of ossifying fibroma involves its complete removal using curettage, enucleation, excision, or en bloc resection. This case report presents an unusual case of ossifying fibroma of the maxillary sinus. We describe a Caldwell-Luc operation with a lateral window approach for excision of an ossifying fibroma of the maxillary sinus.

Ossifying fibroma is a slow-growing benign neoplasm that occurs most often in the jaws, especially the mandible. The tumor is composed of bone that develops within fibrous connective tissue. Some ossifying fibromas consist of cementum-like calcifications, while others contain only bony material; however, a mixture of these calcification types is commonly seen in a single lesion. Of the craniofacial bones, the mandible is the most commonly involved site, with the lesion typically inferior to the premolars and molars. Ossifying fibroma of the jaw shows a female predominance. Some reports of ossifying fibroma have been published in the literature; however, this report continues the research on this topic by detailing 3 types of ossifying fibroma findings on panoramic radiographs and cone-beam computed tomographic images of 4 patients. The radiographs of the presented cases could help clinicians understand the variations in the radiographic appearance of this lesion.

Cardiac fibroma is a rare benign tumor of the heart that occurs primarily in infants and children. Prognosis depends on size, extent and site of tumor. Cardiac fibroma may invade the conduction system, papillary muscle and outflw of inflow tract of ventricle. In these situations, its clinical course is very poor Although operative mortality is high, surgical resection is treatment of choice because lethal arrhythmia and sudden death can be developed by the fibroma. A cardiac fibroma was successfully resected from the left ventricular myocardium of a 8 years old male patient in the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital.

Purpose: Fewer than 100 cases of calcifying aponeurotic fibroma have been reported in the literature since this entity was initially described by Keasbey in 1953 who called it calcifying juvenile aponeurotic fibroma. The tumor is a slowly growing, painless mass. In most cases the mass is poorly circumscribed and causes neither discomfort nor limitation of movement. Most lesions occur in children, with a peak incidence ages of 8-14 years. There is no evidence of any increased familial prevalence. Predilection sites are palm, finger, toe, but it also occurs in the wrist, forearm, elbow, upper arm, neck, abdominal wall, lumbar paravertebral area, leg and ankle. We herein describe a rare case of calcifying aponeurotic fibroma occurring on the chin with review of the literature. Methods: A 14-year-old male had painless, slowly growing mass(${\phi}2.5cm$) on a chin for a year. The tumor was excised elliptically under local anesthesia and the excisional site was repaired directly. Due pathological examination was processed. Results: Histological examination revealed an illdefined fibrous growth that extends with multiple processes into the surrounding tissue with centrally located foci of calcification. The tumor is composed of short spindled plump fibroblasts with round or ovoid nuclei separated by collagenous stroma, showing vaguely palisading pattern. Diagnosis of calcifying aponeurotic fibroma was conferred. Postoperatively, the patient did well, and the lesion had not recurred. Conclusion: Fewer than 100 cases of calcifying aponeurotic fibroma have been reported in the literature. The most common occurring sites are palm, finger & toe, but it has been reported in the wrist, forearm, elbow, upper arm, neck, abdominal wall, lumbar paravertebral area, leg and ankle. Two cases of calcifying aponeurotic fibroma occurring on the neck have been reported in the literature. To the authors knowledge, our case of calcifying aponeurotic fibroma occurring on the chin is the first to be reported.
