[Considerations about the physiopathological and clinical significance of the oligclonal serum pattern (author's transl)].

The fortuitous report of the change of serum electrophoretic pattern from the oligoclonal to the monoclonal type in a patient with Hodgkin's disease has been the starting point for some considerations about the physiopathological and clinical significance of the oligoclonal serum pattern. The AA. carry out a critical review of the ordinary electrophoretic methods, underlining some problems related to a good visualization of the oligoclonal serum pattern.
