This is a case report of a reactive lesion which occurs only in the gingiva. This lesion is of a long duration causing erosion of the superficial bone. Histologically it is similar to other epulides of the gingiva but in addition contains ossified tissue. The lesion's confusing terminology is being discussed in view of its understanding to an American-trained or a British-trained surgeon. A rev...

Central ossifying fibroma is a benign, slow-growing tumor of mesenchymal origin with a predilection for the mandibular premolar and molar areas. The immunophenotype of T cells involved in the antitumor response against this benign tumor is unknown. In this case report, we described a case of a 48-year-old woman presenting with a very large recurrent ossifying fibroma in the mandible, which was ...

Cemento-ossifying fibroma (COF) of maxilla is comparatively rare lesion of the maxillofacial region. There is often a misdiagnosis in the category of fibroosseous lesions, owing to an overlap of clinical, histological and radiographic features amongst the separate entities. We present a case of giant maxillary COF causing extensive disfiguration of the face, along with extensive review of the c...

AIMS AND OBJECTIVES To study the clinical, histological features of peripheral and central ossifying fibromas and also to compare between them. MATERIALS AND METHODS The sample comprised a total 50 cases of ossifying fibromas [25 central ossifying fibromas (COF) and 25 peripheral ossifying fibromas (POF)] inclusive of cemento-ossifying fibromas. RESULTS The mean age is 28.2 years in POF and...

Juvenile aggressive ossifying fibroma (JAOF) is an uncommon benign lesion which is distinctly aggressive in behavior with high tendency for recurrence. It appears in early age and in 79% of patients is diagnosed before 15. It has two histological variants: psammomatoid and trabecular, with the latter being less common with a stronger tendency to recur. In this article, we present a case of trab...

Focal gingival enlargements are a diverse group of lesions with almost similar clinical presentation but varied etiology and histopathology. The actual cause of peripheral ossifying fibroma (POF) has been debated over many years. POFs are usually seen in childhood and younger ages. There is a slight female predilection. It is usually localized, rarely generalized. Usually, the treatment option ...

OBJECTIVE To perform a comparative study of the cellular proliferation in the peripheral and central fibromas. MATERIAL AND METHODS Immunohistochemistry for PCNA and the AgNOR technique were performed in 9 cases of peripheral odontogenic fibroma (POF), in 4 cases of odontogenic fibroma (OdF), in 8 cases of peripheral ossifying fibroma (PEOF) and 7 cases of ossifying fibroma (OsF). The Kruskal...

Peripheral ossifying fibroma (POF) is a slow growing asymptomatic benign tumor which may induce facial asymmetry. It is an occasional growth of the anterior region of mandible and accounts for 3.1% of all oral tumors and 9.6% of the gingival lesions. About 60% of these tumors occur in maxilla and more than 50% of all cases of maxillary POFs are found in the incisors and canine areas. They are t...

Ossifying fibroma (osteofibrous dysplasia) is a rare fibro-osseous lesion made up of fibrous tissue with woven bone formation. It is most commonly found in the tibia and fibula of children ten years of age or younger. The most important differential diagnosis is monostotic fibrous dysplasia, which is radiologically similar but without woven bone rimmed by active osteoblasts like ossifying fibro...
