Peripheral ossifying fibroma
PERIPHERAL OSSIFYING FIBROMA
PERIPHERAL OSSIFYING FIBROMA DEFINATION
Peripheral ossifying fibroma is an exophytic nodular growth, which commonly occurs on the gingiva and is consist of hyperplastic connective tissue containing focal area of bone.
PERIPHERAL OSSIFYING FIBROMA ORIGIN:
The neoplasm develops as a result of reactive proliferation of either the periodontal or the periosteal tissues.
Local irritation always plays a significant role in the development of this lesion.
PERIPHERAL OSSIFYING FIBROMA CLINICAL FEATURES:
Age: Third and forth decades of life. It is found in children or among elderly.
Sex: More common among females
- Peripheral ossifying fibromas occurs exclusively on the gingiva (mainly superficially, from the interdental papilla).
- Occasionally it can develop from the buccal or lingual attached gingiva.
- Rarely the lesion may be seen on the edentulous ridge.
PERIPHERAL OSSIFYING FIBROMA PRESENTATION:
- The neoplasm clinically presents a small, Painless, lobulated swelling on the gingiva.
- It can be either pedunculated or sessile and the overlying mucosa often appears normal.
- The surface of lesion is usually smooth
- The lesions are either hard or firm on palpation and often they are fixed to the underlying tissue.
PERIPHERAL OSSIFYING FIBROMA RADIOGRAPHIC FEATURE:
Radiograph often reveals the presence of some radiopaque foci within tumor mass, having varying radio densities.
PERIPHERAL OSSIFYING FIBROMA HISTOPATHOLOGY:
- Histopathology peripheral-ossifying fibroma exhibits diffuse sheets of proliferating fibroblasts with pump monomorphic nuclei.
- Hyalinization of the collagen fiber is sometimes noticed however, the overall picture represents a hyper cellular reactive tissue.
- Osteoid of varying shape and size are often randomly deposited within the fibrous tissue mass.
- There is no capsule in this tumor
PERIPHERAL OSSIFYING FIBROMA DIFFERENTIAL DIAGNOSIS:
- Peripheral giant cell granuloma
- Fibro epithelial polyp
- Peripheral Ameloblastoma
- Pyogenic granuloma
PERIPHERAL OSSIFYING FIBROMA TREATMENT:
Surgical excision along with through curettage.
