Synovial histopathology of behçet's syndrome.

Abstract
In a blind study, synovial tissue obtained from 7 patients with Behcet''s syndrome and 7 patients with early rheumatoid arthritis could not be distinguished under ordinary light microscopy. A wide spectrum of features was seen in both diseases. These may reflect severity and duration as much as the nature of the arthritis. EM also failed to illustrate any distinct features of Behcet''s syndrome, but immunofluorescent studies indicated consistent deposition of IgG.
