Canine Renal Nephroblastoma: A Literature Review and Case Studies

Abstract

Primary renal tumors are rare in dogs. Only 0.6–1.7% of all tumors are primary renal neoplasia and only about 6% of these are diagnosed as nephroblastomas. Since the origin of a nephroblastoma is usually a defective nephrogenesis and it develops from remnants of the metanephric blastema, the tumor is commonly diagnosed in dogs under 2 years of age.
