| |
− | *May be [[Bones Hyperplastic and Neoplastic - Pathology|osteoma or osteosarcoma, chondroma or chondrosarcoma]], fibroma or fibrosarcoma, myxoma or myxosarcoma, haemangioma or haemangiosarcoma, adenoma or adenocarcinoma

| |
− | *May recur when excised
| |
− | *Necessary to distinguish from neoplasia
| |
− | *Common in cats, less often in dogs, also horses and sheep
