This paper describes the ultrastruotural surface configurations of 5 cases with bone and joint tumors and tumorous conditions, observed by scanning electron microscopy (SEM). The study of pleomorphism of malignant bone tumor cells and their surface ultrastructures shows that there is increased cell surface activity to meet heightened malignancy metabolism. Osteoid osteoma and pigmented villonodular synovitis have no malignant tendencies, according to their surface ultrastructure. SEM iS valuable in investigating tumor cell surface ultrastructure and the intercellular substances and in differentiating malignant bone and joint tumors from benign ones and tumorous conditions.
