Osteosarcoma is a malignant tumor arising from the undifferentiated fibrous tissue of bone and one of the most common primary malignant tumors of bone. The diagnosis of osteosarcoma is based on clinical, radiological and histopathological findings, but the majority of the patients with osteosarcoma can be diagnosed with a reasonable degree of confidence from the combination of the lesion site, age and radiological findings. This is a clinical and radiological observation of 40 cases of osteosarcoma which were experienced at Chonnam National University Hospital, Chosun University Hospital and Kwangju Christian Hospital from 1978 to 1981. The results were as follows : 1. The peak incidence was in the age group from 10 to 19 years in 21 cases (52.5%). 2. In sex distribution, male group showed slightly higher incidence than in female group with the ratio of 1.35 : 1. 3. The most commonly affected site was proximal tibia (35%). The lesion was found around the knee in 65% of the studies cases. 4. Increment of the level of serum alkaline phosphatase was observed in 25 cases (62.5%), and the average value of serum alkaline phosphature in these cases was 5.6 Bessay Lowry units. 5. Radiographically, osteoblastic type was 14 cases (35%), osteolytic type 9 cases (22.5%) and mixed type 17 cases (42.5%). 6. Cortical destruction was obsdrved in 30 cases (75%), and soft tissue mass shadow with calcification was observed in 34 cases (85%). 7. Solid periosteal reaction, sunburst periosteal reaction and Codman's triangle were observed in 35%, 57.5% and 22.5% respectively. 8. At the first visit, lung metastasis was found in 5 cases (12.5%) and inguinal lymphnode metastasis in 2 cases (5%).
