This article aims to analyze the ultrastructure of synovial tissue tumors and determine a set of characteristics of synovial differentiation in order to perform electron microscopy diagnosis of these tumors. The authors studied 3 cases of benign giant cell synovioma and 10 cases of synovial sarcoma with different structures. Normal synoviocytes are divided into two functional states, A and B cells. A cells with hyaluronate and sulphuric acid
