A 7-year old Holstein bull showing marked thickening of left forelimb was diagnosed as pulmonary hypertrophic osteoarthropathy on the histological basis of the exostotic bone of left metacarphus. Thickening of the bone was due to apposition of excessive cancerous bone beneath the periosteum on the shaft. The lung lesion of the bull, chronic suppurative bronchopneumonia was possibly related to pathogenesis of the bone thickening.
