In this period 15 351 dogs were admitted to the Clinic of Dogs and Cats and 2 145 dogs were examined in the cardiological outpatient clinic for dogs. This tumour is located in a typical place - at the base of the heart. Most frequently the tumour manifested in older boxers. Only in one case such a tumour was diagnosed in another breed of dogs. The tumours ranged in size between 3 and 16 cm in diameter. The principal sign accompanying tumours of cardiac base involved dyspnoea but in 3 cases the tumours yielded no clinical signs. All the diagnoses were additionally verified using immunohistochemical examination. We used antibodies to chromogranin A clone DAK-A3 1 100 synaptophysin clone SY38 1 20 and neuron-specific enolase clone BBS NC VI-H14 1 150 . An immunohistochemical examination is vital for the diagnosis since it allows to differentiate histologically distinct types of neoplasia which may locate in the same site and may manifest a similar histological pattern. Introduction Chemodectomas s. paragangliomas represent tumours derived from chemoreceptor cells originating most frequently from aortic body or carotid glomus 1 . The site of their origin may involve also the tympanic cavity and inferior vagal ganglion. In animals the tumours manifest most frequently in the form of a single tumour located at the base of the heart. Less frequently they form .
