E-mail: glaukommers@yahoo.comClinical and pathological aspects of hypertrophic osteopathy in seven dogs were stu-died. Affected dogs had clinical signs of bone involvement and lesions mainly in the long bones of the limbs. The lesions consisted of periosteal new bone formation detected on ra-diographic examination, inspection of bones during the necropsy, and with great detail, in macerated bone specimens. The bone proliferation observed was partially circumferential and occurred mainly in the diaphysis of long bones. It consisted of bone trabeculae of irre-gular size and thickness that were arranged perpendicularly to the original bone cortex. In all cases the lesions were associated with lung neoplasms (primary or metastatic).
