*Also called '''hypertrophic pulmonary osteopathy'''
*In '''all species'''
*Associated with chronic lesions (intrathoracic neoplasm or space-occupying lesion) usually in the thorax
**[[Respiratory Bacterial Infections - Pathology#Tuberculosis|Tuberculosis]]
**[[Pulmonary Neoplasia|Pulmonary neoplasia]]
**[[Pleuritis|Granulomatous pleuritis]]
**Granulomatous lymphadenitis of mediastinal nodes
*Grossly:
**Periosteal proliferation of bone on '''diaphyses''' of distal limbs
**Progressive and bilateral
*Histologically:
**Hyperaemia of periosteum
**Deposition of new bone
**Width of cortex may double in a few weeks
*Postulated to be due to stimulation of vagus by intrathoracic lesion -> increasing blood floow to extremities -> thickening of periosteum
