title: Development of biclonal gammopathy in a patient with von Recklinghausen's neurofibromatosis.
abstract: A well established case of von Recklinghausen's neurofibromatosis, in which a biclonal gammopathy developed, has been studied. One of the paraproteins was characterized as IgG kappa, the other as IgG lambda. This combination of anomalies has not been described previously in the literature.
