Chordoma in a cat.

A chordoma within the deep musculature adjacent to C3 and C4 was excised from a 14-year-old castrated domestic cat. Metastatic chordoma developed in a prescapular lymph node 10 months later. At necropsy 11 months after complete excision of the primary tumor, metastases were found in both retropharyngeal lymph nodes.
