Canine paraganglioma associate with bankruptcy cardiac: case report
Keywords:
canine, heart tumors, paragangliomaAbstract
Primary neoplasms of the heart are rare in all domestic species, however, paragangliomas
occur in dogs. In this case report, a Golden Retriever breed was sent to the Pathology
Department of Veterinary Veterinary Hospital - UNESP, Botucatu with sudden death. At
necropsy, the heart showed neoformation adjacent to the caudal vena cava and in the right
atrium and, in both lungs were observed many nodes. The collected material was processed
and stained with hematoxylin-eosin. It was also performed immunohistochemical panel for
anti-cytokeratin, anti-vimentin, anti-desmin, smooth muscle anti-alpha actin, anti-factor VIII
and anti-enolase specific neuron (NSE). Based on the clinical and morphological findings,
anatomical, histological, additionally, to positive immunoreactivity for NSE, the tumor was
characterized as a paraganglioma grade 2 of malignancy. This report aims to contribute by
adding data to the literature of this neoplasm.
