Living with Ossifying fibroma

A rare, non-cancerous tumor of the skull and face bones that causes painless swelling of the bone.

Understanding Ossifying fibroma

Juvenile ossifying fibroma is a rare, benign tumor of the bones of the skull and face.

It is a fibro-osseous tumor, meaning there is an overgrowth of bone. People usually notice gradual or rapid painless swelling of the affected bone. Depending on the location, it can rarely cause a bulging eye or nasal blockage. In some cases it can be aggressive, with rapid growth and significant changes in facial appearance.

GARD doesn't list specific symptoms for this condition yet. Based on its summary, features may include:

  • Painless swelling of a skull or face bone

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
