title: [Non-secreting plasmacytomas].
abstract: In non-secernent plasmocytomas there are no characteristic changes of serum protein. Diagnostic difficulties may be overcome by cytomorphological examinations, immunofluorescence and electron microscopy. By referring to 4 own observations the value of the electron microscopic characteristics of plasma cells is demonstrated. Subtile investigations in protein diagnostics are required for avoiding incomplete monoclonal immunoglobulins which may greatly enter the kidneys to be overlooked. Generally the prognosis of non-secernent plasmocytomas is not worse than that of other forms.
