title: [The rhagocyte (author's transl)].
abstract: The "rhagocyte" (Delbarre) was defined with the aid of own results and results from the literature as an unity of structure and function of phagocytic cells in synovial fluids. Rhagocytes are an ubiquitous phenomenon in most cases of inflammation in joints detectable with nonspecific methods and are not a specific sign for the diagnosis of rheumatoid arthritis. The inclusion bodies of rhagocytes were demonstrated as immunoglobulin complexes with fixation of complement (IgG/IgM/C) by means of the immunofluorescence technique. In these specific preparations the rhagocyte has an importance as rheumatoid arthritis cell (R.A. cell) as defined by Hollander. --A definition of the rhagocyte and a description of histochemical results is given in a synopsis of characteristical properties of inclusion body cells. Moreover, a representation of the morphogenesis and value of the rhagocytes in a concept of the pathogenesis of rheumatoid arthritis, the in vitro and in vivo reproduction of rhagocytes and its value for the diagnosis in diseases of joints is given.
