Abstract


Cutaneous growths arising from the endothelial cells of blood vessels were studied in three dogs (Two in male cocker spaniels and one in male Labrador). All the three growths were surgically excised and referred to the Department of Veterinary Pathology, Tirupati for histopathological confirmation during the period from August 2015 to December 2015.Gross examination revealed, firm reddish, soft dark red and soft greyish red coloured masses and are diagnosed based on histopathological features as hemangiosarcoma, cavernous hemangioma and lipohemangioma respectively. In the case of hemangiosarcoma, severe necrosis along with the presence of blastomyces organisms as a secondary infection was also noticed. Occurring of these tumours might be because of exposure of lightly pigmented areas to Ultra Violet radiation.
