9262/0 Ossifying fibroma
|ICD-O-3 topography code:||C40-C41|
A well circumscribed lesion of the bone, most frequently arising from the posterior mandible. It is characterized by the presence of fibrous tissue and a mineralized component which may be woven bone, lamellar bone, or cementum-like material. Complete removal is recommended, since it continues to enlarge if left untreated.
