BACKGROUND The purpose of this work was to perform a systematic review regarding ossifying fibroma and its multiple variants of the paranasal sinuses, and to identify any clinical differences between the multiple variants. METHODS A search of the U.S. National Library of Medicine (PubMed) database was performed for the non–Medical Subject Heading (MeSH) search term “ossifying fibroma.” The bi...

Intra-osseous fibromas of the jaw are classified by origin. Intra-osseous odontogenic fibromas have odontogenic epithelia, while desmoplastic fibromas do not. However, it is often difficult to determine the odontogenic origin for central fibromas. Three subjects with a diagnosis of intra-osseous fibroma were examined. Case 1 was a 35-year-old man found to have a panoramic radiograph from the ri...

UNLABELLED INTRODUCTION Nonossifying fibroma is a common fibrous bone lesion in children that occurs in the metaphysis of the long bones of the lower extremities. The lesion rarely leads to aneurysmal bone cyst, which is characterized as a blood-filled space. CASE PRESENTATION We present the case of a 13-year-old Japanese boy with a complaint of discomfort in the thigh and a small, well-de...

Shope fibroma virus establishes a persistent cytoplasmic infection in primary (RK) and serially cultivated (DRK(3)) rabbit kidney cells which is accompanied by a morphological alteration of the cells. The response of such cells to superinfection by other viruses was compared with that of control cells by determining plaque production and virus yield of superinfecting viruses. It was found that ...

Chondromyxoid fibroma; a rarely found tumor, contributing <1% of all primary bone neoplasm. We reported 4-year female child with 1-year history nasal obstruction and facial swelling. Large enhanced lesion amorphous densities spreading into the right cribriform plate floor sphenoid sinus, laterallyinto lamina papyracea, inferolaterally medial wall maxillary posteriorly nasopharynx superior as...

CASE REPORTS Case 1-A boy aged six months was seen in 1969 because of a swelling on the back of the distal part of the right middle finger. He was the fourth child of healthy parents. The tumour had appeared in the third month of life ; it was about 5 millimetres in diameter, firm, not tender, and fixed to the skin but not to the underlying tissues. Biopsy showed a dermatofibroma with no sign o...

The present case is of peripheral ossifying fibroma in the mandibular anterior gingiva of a 30 year old female. The lesion was asymptomatic, reddish, firm and penduclated. The lesion was surgically excised and at follow up of 1 year showed no recurrence. Histological assesment showed connective tissue stroma with osseous like calcification. Suggestive of peripheral ossifying fibroma.

Central odontogenic fibroma (COF) is an extremely rare benign tumor that accounts for 0.1% of all odontogenic tumors. It is a lesion associated with the crown of an unerupted tooth resembling dentigerous cyst. In this report, a 10-year-old male patient is presented, who was diagnosed with central odontogenic fibroma of simple type from clinical, radiological, and histopathological findings.

Desmoplastic fibroma (DF) is a rare, benign but locally aggressive, intraosseous lesion with a high tendency of local recurrence. In this report the actual literature is reviewed regarding epidemiological data, pathology, clinical diagnostic criterias, therapy and prognosis. Moreover, a report of an interesting case is included localized in the mandibular corpus.
