Cervical chordoma in a domestic ferret (Mustela putorius furo) with pulmonary metastasis.

A 4-year-old, male neutered domestic ferret (Mustela putorius furo) was evaluated for a mass in the left cervical region. The owner elected humane euthanasia, and an autopsy was performed, revealing a neoplasm with infiltration into the left cranial articular fovea of the atlas and cervical vertebrae, with regional compression of the spinal cord. Histologic evaluation was consistent with cervical chordoma. At autopsy, a left cranial lung lobe nodule was observed. Additional sectioning and histologic evaluation revealed multiple foci of metastatic chordoma at this site. A small focus of micrometastasis was also detected in a section from the right lung lobes. Chordoma is the most common musculoskeletal neoplasm of ferrets, arising from remnant fetal notochord. To our knowledge, pulmonary chordoma metastasis has not been previously reported in the ferret. This case demonstrates the potential for visceral metastasis of chordoma in the ferret, as has been reported in other species.
