title: [Unusual location of extramedullary plasmacytomas (author's transl)].
abstract: Two cases of solitary extramedullary plasmacytoma, one of the nasopharynx and one of the tongue are reported. Although there was no paraprotein secretion present, we were able to demonstrate an intracytoplasmic monoclonal immunoglobulin (type IgG-kappa) by immunohistochemical methods. Twelve months following surgical treatment both patients locally and by serum controls are free of residual disease. We confirm former studies in the literature that the prognosis of solitary extramedullary plasmacytomas seems to be good after surgical or radiation therapy. Continuous individual follow-up including serum and X-ray controls are obligatory.
