Synovial sarcoma in a cat.
A 9-year-old male castrated cat was examined because of right forelimb lameness of 2 months' duration. The right cubital area was large, and the range of motion of the cubital joint was limited. Radiography revealed a mild periosteal reaction of the humerus, radius, and ulna. There was cortical remodeling of the distal portion of the humerus and punctate osteolysis within the proximal portion of the ulna. Arthrocentesis was performed and neoplastic cells were found, which led to a tentative diagnosis of osteogenic sarcoma or synovial cell sarcoma. Histologic diagnosis of synovial cell sarcoma was made after amputation of the limb.
