Abstract

A 12-year-old, female Shih Tzu was brought in because of a left forelimb swelling. X-rays and fine needle aspirates showed a mass in the distal antebrachium, and the lesion was tentatively diagnosed as a parosteal osteosarcoma. Ten days later, the left forelimb was amputated. Histopathologically, the disease was confirmed as parosteal osteosarcoma. In thoracic X-ray examinations, two definite pulmonary metastases were found on the 557th day after amputation, in spite of occasional chemotherapy with carboplatin. Because the tumors in the lung gradually grew larger, and coughing became severer, the cranial lobe of the left lung was removed on the 725th day after amuputation, and the postoperative course was good. However, on the 73rd day after the pulmonary metastasectomy, a number of small nodes were seen everywhere throughout the whole lung, indicating recurrence. Even so, the dog's quality of life was satisfactory, being almost free of coughing for six months after resection of the lung lobe. Finally the coughing worsened, and the dog died on the 230th day after metastasectomy, that is, 955 days after amputation.
