Neuroblastoma of the Adrenal Gland in a Ferret

Abstract

A 5-year-old castrated male ferret was referred for hind limbs paresis and subcutaneous mass at the lumber area. Based on clinical examination including computed tomography, the extension of the mass to the abdominal cavity was confirmed. The exploratory laparotomy revealed that the mass at the cranial area of the left kidney extended dorsally to the vertebra and to the subcutis. The excised mass was histologically diagnosed as medullary tumor of the adrenal gland, and some neoplastic cells showed beta Ⅲ-tubulin-, doublecortin-, and neurofilament-positive. Based on these findings, the tumor was considered as a neuroblastoma.
