Aortic Body Tumor in a Dog


Abstract: Aortic body tumors were investigated macroscopically and microscopically in a 2-year-old, clinically normal, male cross-breed dog. Two tumor masses measuring 4 x 4 x 3 cm in size were determined. One of them was located on the A. subclavia dextra and the other one was located on the A. carotis communis dextra and they adhered to the adventitia of these vessels. The tumor masses were encapsulated within a thin capsule and lobulated with yellowish-brown areas and were elastic in structure. Yellowish-white and red-brown focal areas were seen on the cut surface. In addition, a yellowish-white tumor mass measuring 2 x 3 x 3 cm in size was present in the facies auricularis of the heart base at the atrioventricular border, at the level of origos of the sulcus interventricularis paraconalis and at the caudalis of the truncus pulmonalis.
