Neoplastic Arthritis in Small Animals

Synovial cell sarcoma is the most common malignant tumor involving the joints. The tumor arises from primitive mesenchymal cells outside the synovial membrane. Clinical signs include lameness and joint swelling. Radiography reveals soft-tissue swelling and a periosteal reaction. Pulmonary metastasis is detected in ~25% of animals at initial examination.
