A Surgical Case of Canine Malignant Mixed Mammary Tumor Metastasized to the Thoracic Vertebral Body

Abstract

A female toy poodle dog showed severe pain due to metastasis of malignant mixed mammary tumor on the 6 th thoracic vertebral body (T 6) . The T 6 was excised for pain relief and a bone graft obtained from the right iliac wing was placed into the defect under thoracotomy. The T 5 and T 7 were fixed with a miniature plate and screws to stabilize the graft. The quality of the patient's life was markedly improved due to the reduction of pain, although the dog died of systemic metastasis on the 76 th day after the operation.
