Multiple cartilaginous exostoses of rib in dog: a case report

AbstractOsteochondroma is a proliferative condition that affects cartilage and bone in rare cases. Osteochondroma of the ribs is uncommon in dogs, and its manifestation has the potential to induce compression and harm to the vasculature and internal organs of the thoracic cavity. The discoverable evidence of this condition was encountered during the dissection of the chest of a 5-year-old male dog of mixed breed, who had no previous record of illness. The salient features noted during the dissection process were the identification of four dome-shaped masses which evinced a solid consistency and were found to be located in the right hemithorax, thus leaving an impression on the caudal lobes of the right lung. The masses were distinguished by their smooth surfaces and hard texture. Upon histological analysis, the lesion was characterized by spongy bone enveloped by periosteum and hyaline cartilage. The results obtained from the study ’s macroscopic and microscopic levels indicated multiple cartilaginous exostosis.
