Objective: To report clinical outcome associated with treatment of canine spinal cord nephroblastoma (CSN). Study Design: Case series. Animals: Dogs (n=10) with histopathologically confirmed CSN. Methods: Records of dogs with CSN were reviewed and clinicopathologic, diagnostic imaging, treatment, outcome, and survival data were collected. Results: CSN resulted in clinical signs of chronic, progressive T3-L3 myelopathy in young, large breed dogs, with an overrepresentation of German Shepherd Dogs (n=4). All CSN were located between T9 and L2.

An 11-year-old neutered male boxer was presented for treatment of a multilobular osteochondroma of the hard palate. The mass was surgically resected and the hard palate defect was reconstructed using an angularis oris axial pattern buccal mucosal flap. No local recurrence was reported 6 mo after surgery.

Case description: This clinical report describes a 10-year-old female spayed German Shepherd dog cross that was presented with cellulitis of the left proximal forelimb and osteomyelitis of the left proximal humerus, and was ultimately diagnosed with metastatic osteosarcoma. Clinical findings: The diagnosis of cellulitis and osteomyelitis was made using ultrasound, radiography, cytology and histopathology, all of which were consistent with cellulitis and osteomyelitis. Cultures were negative.

A 5-year-old, male neutered, mixed breed dog was presented for left forelimb lameness and swelling over the left distal radius. A primary bone tumor of the distal radius was diagnosed and limb-sparing surgery of the left forelimb was performed using a tantalum metal-DCP endoprosthesis. Post-operative histopathology confirmed osteosarcoma.

Intra- and extra-articular primary synovial chondromatosis (SC) was observed in a five-year-old, entire male German Shepherd. Thousands of small cartilaginous nodules were removed from the stifle joint as well as from several adjacent muscles. Diagnosis of SC was established based on clinical, radiographic and biopsy results. The owner declined to have a new surgery performed for complete nodule removal and partial synovectomy.

A 14-year-old domestic shorthair cat was evaluated for a 3-month history of head pressing and circling. Neurological examination suggested a supratentorial problem, predominantly on the left side. An extradural mass extending from the rostral frontal lobes caudally to the level of the caudal aspect of the corpus callosum was found with magnetic resonance imaging. A bilateral rostrotentorial craniectomy combined with a frontal sinus craniectomy was performed for mass removal. A gamma-irradiated calvarial allograft was used to repair the calvarial defect.

Abstract Canine osteosarcoma (OS) is an aggressive tumour that accounts for approximately 90% of primary bone tumours in the dog. Although the standard treatments (including limb amputation/sparing, chemotherapy and palliative radiotherapy) have significantly increased survival rates, almost 90% of animals will eventually develop predominantly pulmonary metastases. Despite advances in various therapies, prognosis remains poor, with median survival times ranging from 3months to 1year and <20% of dogs survive for >2years following diagnosis.
