title: Synovial deposit of osmic acid after intra-articular injection. Anatomical and radiologic study of a case.
abstract: An anatomical and radiologic study of a synovial autopsy specimen 32 months after an intra-articular injection of osmic acid for the local treatment of a rheumatoid synovitis. Osmium deposits are seen within peripheral cells of a fat lobule and also in a few histiocytes of the scar tissue which replaced the rheumatoid synovitis. These osmium deposits in the fat cells are present in a sufficient quantity to give a radiologic opacity.
