The pathogenesis remains unknown. It generally occurs between the second and fourth decade, with a 1:5 male:female ratio. The most frequent location is the mandible (75%). It usually presents as a by slow-growing, progressive, painless bone enlargement, with no other symptoms. COF can be present in conditions such as hyperparathyroidism jaw tumour syndrome or be associated with kidney lesions.
