A retrospective study of 38,398 cases, that were submitted from 1963 to 1988 to the Pathology Department at the School of Veterinary Medicine and Husbandry of the National Autonomous University of Mexico (UNAM), was performed. Among these cases, there were 29 paragangliomas. It was possible to run special stains like PAS, Giemsa and Grimelius in 16 of them. Results were: 5 paragangliomas of aortic body, 3 of carotid body, 1 pheochromocytoma and 1 neuroblastoma. There were also: 3 Schwanomas, 1 mammary gland adenocarcinoma and 1 adenocarcinoma, which had been previously diagnosed as paraganglioma. From the 10 paragangliomas, 8 were found in male and 2 in female. Breeds with the highest frequency were: Cross-breed, 3 cases; Boxer, 2 cases, Fox Terrier, one case; German Shepherd, one case; Doberman, one case; Basset Hound, one case and one in Napolitan Mastiff. Results of the special stains showed 7 cases positive to PAS, 2 to Giemsa and 8 to Grimelius. Just 1 case showed positivity to all stains. It was possible to verify that the incidence of paragangliomas is low and their diagnoses both ante mortem and post mortem is difficult.
