A 9‐year‐old girl presented left facial asymmetry for 2 months and was hospitalized in the Department of Otolaryngology‐Head and Neck Surgery, Beijing Tongren Hospital in June 2013. A paranasal sinus computed tomography (CT) scan showed a lesion in left maxillary sinus (MS). No nasal obstruction, rhinorrhea, decreased vision, proptosis or epistaxis was ever complained. No abnormal finding was n...

Background: Peripheral Cemento-Ossifying Fibroma (PCOF) usually presents as epulis, represents 3.1% of all oral tumors and 9.6% gingival lesions, is difficult to distinguish clinically radiographically, requires anatomic histopathological confirmation, peaking in the 2nd 3rd decades, high recurrence 8-20%. Objective: To report case management posterior maxilla with conventional surgery excision...

This report contains a statistical review of 559 cases of lesions forming hard tissues that were diagnosed by the departments of Clinical Pathophysiology and of Pathology at Tokyo Dental College from 1966 to 2001. Sixteen kinds of lesions which were related to the formation of bone, cartilage or cementum were analysed: osteoma, osteo-chondroma, chondroma, osteoid osteoma, osteoblastoma, ossifyi...

Various terms have been suggested to describe non-ossifying fibroma including fibrous cortical defect, cortical desmoid, metaphyseal fibrous defect and non-osteogenic fibroma. Regardless of the term used, they probable all refer to abnormal osteoclastogenesis at the metaphyseal region. Non-ossifying fibroma is a benign fibrogenic tumor primarily affecting children and adolescents. It is the mos...

Intraoral ossifying fibromas have been described in the literature since the late 1940s. Peripheral ossifying fibroma (POF) is usually a fibroma of the gingival which shows areas of calcification or ossification. It is a nonneoplastic enlargement of gingiva. Due to its clinical and histopathological similarities, some POFs are believed to develop initially as a pyogenic granuloma that undergoes...

INTRODUCTION Peripheral giant cell granuloma and peripheral ossifying fibroma are clinicopathologically distinct gingival lesions. Both are included in clinical differential diagnoses of common benign and reactive gingival epulides in humans. It is often impossible to make a clinical distinction between the two entities, thereby making definitive diagnosis dependent on histopathologic features....

Ossifying fibroma of the jaw is a benign fibroosseous tumour. The growth of it is slowly and it is well circumscribed. Occurrence of multiple ossifying fibromas (synchronous) is rare in the jaw, and only a few cases have been documented. The most of these cases were in only maxilla. The fewer cases were reported in both of maxilla and mandible. We report a case of bilateral synchronous ossifyin...

Large, atypical peripheral ossifying fibromas are known as giant peripheral ossifying fibromas.  These lesions have often been associated with heterogeneous clinical and radiographic characteristics subsequently leading to their misdiagnosis.  Biopsies have been the gold standard for the diagnosis of such lesions.  This study reports on an acute presentation of giant peripheral ossifying fibrom...

BACKGROUND Giant cell fibroma is a type of fibrous tumour of the oral mucosa which rarely affects children under the age of 10. The purpose of this paper was to contribute two clinically and histologically documented cases of giant cell fibroma in the free gingiva of a 7 and 6 year old boys. METHODS Both nodules were presented in the mandibular anterior region. In the differential diagnosis s...
