Juvenile ossifying fibroma is an expansive intraosseous lesion of the bones. In most patients, the tumors are located in the facial bones. The main characteristics of juvenile ossifying fibroma are the early age of onset, localization of the tumor, radiological pattern and a tendency for recurrence. This article describes a case of expanded juvenile ossifying fibroma in the right maxilla in a 12-year old boy. The lesion was removed totally by surgery under general anesthesia. The patient showed no radiological signals of recurrence approximately two years after surgery.

Cementifyng fibroma is one of the fibro-osseous lesions. All fibro-osseous lesions containing cementum are considered to be of periodontal membrance origin and is most common in the maxilla and mandible. Rarely, cementifying fibromas are seen in other craniofacial bone except jaw lesion. A diligent search in the available world literature show only two documentation of cementifying fibroma in the fronto-orbital bone. This case is third case but first in the frontal bone beyond orbit. The authors report a case of cementifying fibroma of the frontal bone in 12-year-old female patient.

This study was undertaken to document and better defined this condition to help clarify this clinical and radiographical appearances by the analysis of clinical and radiographical features of fibro-osseous lesions in the jaws. A study was made of a series of 128 cases with fibro-osseous lesions. The obtained results were as follows. 1. Fibrous dysplasia of the jaws occurred with equal predilection for males and females. But the females occurred in 68% of cemento-ossifying fibroma and 75% of periapical cemental dysplasia. 2. 43% of fibrous dysplasia and 32% of cemento-ossifying fibroma occurred in the 2nd decades and 33% of periapical cemental dysplasia in 5th decades. 3. 62% of fibrous dysplasia occurred in the maxilla, 73% of cemento-ossifying fibroma in mandible, 90% of periapical cemental dysplasia in mandible. 4. 98% of fibrous dysplasia occurred in premolar-molar region, 77% of cemento-ossifying fibroma in molar region, 68% of periapical cemental dysplasia in incisor region. 5. In serial radiographic features, mature stage were 55% of fibrous dysplasia, 45% of cemento-ossifying fibroma, 59% of periapical cemental dysplasia. 6. 87% of fibrous dysplasia had monostotic lesion, 67% of periapical cemental dysplasia had multiple lesions. 7. In fibrous dysplasia and cemento-ossifying fibroma, migration of tooth occurred in 61.7% and 36.4%, retention of tooth occurred in 4.3% and 9.1%, loss of lamina dura occurred in 6.4% and 9.1%, and root resorption had not occurred in fibrous dysplasia, but occurred in 18% of cemento-ossifying fibroma, displacement of mandibular canal occurred in 14.9% and 31.8%.

In our preliminary study to find antiviral or antitumor agents from Korean natural products, we found that the Shope fibroma virus (SFV) induced fibromas reaching maximum size at $5{\sim}6$ days with spontaneous disappearance at $15{\sim}20$ days after SFV intracutaneous inoculation into Korean domestic rabbits. However, the sizes of fibromas of rabbits at day 5 after virus inoculation were significantly different individually. Assuming that the variation of tumor size was due to either susceptibility or the preexisting antibodies against SFV in the Korean domestic rabbits, the rabbits were checked for the antibodies against SFV by IFAT using SFV infected RK13 cells. The antibody positive rate of normal Korean domestic rabbits was 32.8% and the sizes of the fibromas of the positive rabbits were significantly smaller than those of negative rabbits (p<0.0001). The fibroma sizes were dependent on the antibody titers of rabbits to SFV. The sizes of fibromas after inoculation of SFV into immunized rabbits were about one tenth of those by the first inoculation into normal rabbits. This is the first report on the antibody prevalence against SFV among normal Korean domestic rabbits and it suggest the existence of a wild fibroma virus or related virus in Korea.

Desmoplastic fibroma of bone is rare, involves usually long bones, and histologically resemblance to the desmoid tumor of soft tissue. It is benign, but aggressive locally. Recurrence rate is high when treated with simple curettage and bone graft. Moreover, malignant transformation of desmoplastic fibroma with recurrence has been reported very rarely, and then it make us review again whether previous tumor probably was low grade malignant tumor. We report a surgically proven case of osteosarcoma arising from desmoplastic fibroma. A 17 years old male had been treated for a desmoplastic fibroma of the proximal tibia with curettage and bone graft. But after 11 years, the patient showed recurrence accompanying malignant transformation with osteosarcoma. This is very rare case of an osteosarcoma arising in a desmoplatic fibroma of the proximal tibia.

This study was undertaken to document and better define this condition to help clarify this clinical and radiographic appearances by the analysis of clinical and radiographic features of cementoma. A study was made of a series of 104 cases with cementoma. This investigation of cementoma revealed the following features: 1. The female occurred in 73% of periapical cemental dysplasia and benign cementoblastoma, and 80% of cementifying fibroma. 2. 40% of periapical cemental dysplasia occurred in the fifth decades, and 73% of benign cementoblastoma during the second and third decades, while there was no age predilection in the cementifying fibroma. 3. 63% of periapical cemental dysplasia occurred in the mandibular anterior region. 91% of benign cementoblastoma and 80% of cementifying fibroma occurred in the mandibular premolar and/or molar region. 4. There were no cases complaining the associated clinical signs and subjective symptoms in the periapical cemental dysplasia, however the patient complained the pain in 36% of benign cementoblastoma and 40% of cementifying fibroma. 5. There were no cases expanding the cortical plates in the periapical cemental dysplasia, however 73% of benign cementoblastoma and all of 5 cases of cementifying fibroma showed the expansion of cortical plates. 6. Several radiographic features of the periapical cemental dysplasia were shown: a. 29% of the cases had multiple lesions. b. 53% of the cases were in the mature stage. c. During the osteolytic stage, the alveolar lamina dura was lost in 89% of the cases.

Desmoplastic fibroma is a rare primary tumor of bone that histologically and biologically mimics the extra-abdominal desmoid tumor of soft tissue. This report is dealt with two cases of desmoplastic fibroma occurring in a 22-year-old male, scapular lesion and 34-year-old male, pubic lesion. Radiologically, the tumors were lucent and expansile lesions. Histologically, they contained slender spindle cells and various amounts of collagen fibers. Radical excision was done on both cases and no recurrence was reported. Because of its rarity, we report two cases of desmoplastic fibroma.

Chondromyxoid fibroma is a benign tumor in adolescents and young adults. The most common location of the tumor is the proximal one-third of the tibia. Chondromyxoid fibroma accounts for less then 1% of all bony neoplasms and foot is affected in about 20% of all cases. The authors have described a case of chondromyxoid fibroma of the first metatarsal which had been recurred 7 months after curettage and iliac bone graft. En bloc resection and reconstruction of the metatarsal with autogenous iliac bone graft were performed. The results were satisfactory and the patient was free of local recurrence at two years follow-up.

A fibroma arising in the right ventricle outflow tract of a 14 month-old infant was successfully removed. The patient was first seen because of shortness of breath and tachycardia. Pertinent clinical and laboratory findings included a grade II/VI systolic murmur, blood pressure of 120/60 mmHg, slight cardiomegaly on chest X-ray, a mass obstructing the outflow tract of the right ventricle on echocardiography and magnetic resonance imaging. On october 30,1992, under cardiopulmonary bypass, a 4cm x 3cm x 3cm tumor was resected from the right ventricular outflow tract, together with a portion of the ventricular wall. Histologically, it was diagnosis as a fibroma. The patient was sent home on the 6th postoperative day following an uneventful recovery form the operation. Although cardiac fibroma is the second most common cardiac tumor in infancy and childhood, it is usually found in the left ventricle and one arising in the right ventricle is considered rare. Although it is a benign tumor, it could produce a severe cardiac dysfunction and even sudden death, depending on its size and location. With the advance in diagnostic techniques and operative management, there is a renewed interest in the early detection and operative removal of these tumors. The case herein presented is the first such case successfully managed and reported in the Korean literature.

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 with mass excision several times over a period of two years and eight months, and followed up. After biopsy gathered because of signs of recurrence, she was diagnosed with low-grade osteosarcoma. The patient underwent wide excision, segmental mandibulectomy, and reconstruction with fibula free flap. The aim of this report is to raise awareness of the possibility that cemento-ossifying fibroma can transform into osteosarcoma and of the consequent necessity for careful diagnosis and treatment planning.
