title: [A plasmacytoma with changing paraproteinemia].
abstract: A disease on myeloma is described which originally showed an IgA paraproteinaemia. 3 years later a paraprotein of IgM-typ could be identified by the immunoelectrophoresis. Clinical progress and examination of the bone marrow revealed the unequivocal diagnosis of multiple myeloma. In spite of IgM paraproteinaemia the formation of Waldenströms' disease did not occur.
