Abstract
The hemangioma and hemangiosarcoma are mesenchymal neoplasms from the vascular endothelium, and the dog is the domestic animal more commonly affected. At the veterinary hospital of the Federal University of Uberlândia, we reviewed the files from the Animal Pathology Laboratory from 2002 to 2014. The epidemiological data and the frequency of dogs diagnosed with hemangioma and hemangiosarcoma were verified, correlated, and statistically tested. 64 cases of hemangioma and 128 cases of hemangiosarcoma were identified. For hemangiomas, there was no difference in frequency regarding sex and breed. The cutaneous hemangiomas were more frequent than visceral hemangiomas. Female dogs and adult animals were often affected by hemangiosarcoma, as well as the Pitbull breed. The hemangiosarcomas had been predominantly cutaneous and medium size tumour was the most frequent for this neoplasm.
