- 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 woven bone
- No recognisable osteoblasts - differentiates from ossifying fibroma
- Radiographically:
- Smooth edged areas of radiolucency
- Usually resolves
- Lesions in head may cause problems eating or cause pressure on the brain
