*In young horse, dogs and cats
*Rare
*Developmental?
*Grossly:
**Expansive fibro-osseous lesions
**In metaphyses
**Firm fibrous masses
**Gritty when cut
*Histologically:
**Fibrous stroma with trabeculae of [[Bones - Anatomy & Physiology|woven bone]]
**No recognisable [[Bones - Anatomy & Physiology|osteoblasts]] - differentiates from [[Bones Hyperplastic and Neoplastic - Pathology#Ossifying fibroma|ossifying fibroma]]
*Radiographically:
**Smooth edged areas of radiolucency
*Usually resolves
*Lesions in head may cause problems eating or cause pressure on the brain
