Juvenile Aggres Os F

OMFP 2 Flash Card 2 - Juvenile aggressive ossifying fibroma

QuestionAnswer
Clinical features of juvenile aggressive ossifying fibroma (1) The fibro-osseous lesion is like other types of ossifying fibroma in many aspects except they tend to have more rapid growth than central ossifying fibroma and a larger growth capacity.
Demographics of juvenile aggressive ossifying fibroma It is found in younger patients within their first two decade of life, with a slight male predilection.
Microscopic features of juvenile aggressive ossifying fibroma The specimen will appear as a central ossifying fibroma with more malignant, highly cellular and active regions (Like fibroblastic osteosarcoma). As in the other types of COF there are 2 microscopic types: trabecular and psammomatoid.
Differential diagnosis of juvenile aggressive ossifying fibroma Ossifying fibroma Osteoblastoma Osteosarcoma Peripheral ossifying fibroma when on gingiva Fibrous dysplasia CGCG (early lesions)
Treatment options for juvenile aggressive ossifying fibroma Treatment is surgical resection and in large lesions a hemi-mandibulectomy may be required to eliminate recurrence.
Clinical features of juvenile aggressive ossifying fibroma (2) They often will expand the cortex (maybe with perforation) These also may become large and greater than 10 cm. in diameter.
Clinical features of juvenile aggressive ossifying fibroma (3) Clinically these will appear as a circumscribed radiolucency or mixed radiolucency and radiopacity.
Clinical features of juvenile aggressive ossifying fibroma (4) A sclerotic border is present in some cases. “Ground-glass” opacification or a multilocular “honeycomb” pattern also may be observed potentially because of the rapid growth rate.
Prognosis for juvenile aggressive ossifying fibroma There is a high recurrence rate without aggressive surgery, so the prognosis is fair due to the recurrence potential.
How do you diagnose juvenile aggressive ossifying fibroma? Clinical correlation of patient history, clinical findings and radiographic interpretation will be utilized with a biopsy of the lesion for definitive diagnosis.
