Aortic body tumors in dogs from Northern Paraná, Brazil

ABSTRACT

This article describes the occurrence of aortic body tumors in four dogs from Southern Brazil. All dogs were males, more than 9 year of age; most of these were from the Boxer breed of dogs. The animals had large neoplastic growths at the base of the heart, which demonstrated histologic characteristics consistent with that of aortic body tumor. By immunohistochemistry, tissue sections from all dogs reacted positively to neuron specific enolase. These cases might represent the first description of this tumor in dogs from Brazil, as confirmed by immunohistochemistry.
