title: [Study of cellular elements in synovial fluid in scanning electron microscopy].
abstract: Scanning electron microscopy allows a tridimensional morphological study of the cellular elements of the pathological human synovial fluid. The cells are grouped into two populations: macrophage cells and round cells, whose differentiation is more difficult: polynuclears, lymphocytes and synovial cells. The combination of scanning electron microscopy and X-ray diffraction makes it possible to describe and indentify crystals of sodium urate and of triclinical, dehydrated calcium pyrophosphate.
