Rare disease in the dog (Keeshonden race the prearranged one) and less even frequents in the cat, mainly affects to animals gerontes.
The main cause of the primary hiperparatiroidismo is the presence of solitary adenomas (benign tumors), although also are had I decipher primary carcinomas and hiperplasias.
