===Ossifying fibroma===
*Rare
*Of heads of horses and cattle
*Grossly:
**Sharply demarcated expansive mass
**Distort normal bone contour
*Histologically:
**Dense fibrous tissue
**Bone spikules of [[Bones - Anatomy & Physiology|woven bone]] covered by [[Bones - Anatomy & Physiology|osteoblasts]]
**In later stages resembles [[Bones Hyperplastic and Neoplastic - Pathology#Osteoma|osteoma]]
*Malignant transformation has not been reported
