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...

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.

Desmoplastic fibroma is a rare benign tumour of bone. Diagnosis is not easy and is often made by excluding other tumours. Histopathological diagnosis of this tumour is also sometimes not easy. The treatment modalities for this tumour are non-uniform and often controversial. In the present case surgical options were left aside because the patient did not consent to surgery, so radiotherapy was u...

Odontogenic fibroma (OF) is considered an unusual, benign mesenchymal neoplasm and one of the most little-understood lesions amongst all odontogenic neoplasms. The incidence rate of the tumor is from 0% to 5.5%. WHO classified them into intraosseous or central and extraosseous or peripheral variants. It chiefly consists of fibroblastic tissue with an inconsistent amount of inactive appearing od...

Introduction: Peripheral odontogenic tumors are rare and there is no valid information of the frequency of them in the literature. This study aims to obtain the frequency of these tumors. Materials and Methods: The files of oral and maxillofacial pathology (microscopic reports and slides), faculty of dentistry, Shahid Beheshti University of medical sciences served as the source of the material...
