title: Detection of plasmacytoma of the nasal cavity by immunoelectrophoresis of nasal washing fluid.
abstract: A patient with a solitary IgG-lambda plasmacytoma of the nasal cavity is described. Immunoelectrophoresis of the nasal washing fluid showed the presence of the same paraprotein. After radiotherapy the tumour and the paraprotein disappeared. Recurrence of the tumour after 6 months was again associated with the presence of the paraprotein in the nasal washing fluid. Immunoelectrophoresis of nasal washings may offer an easy method in detection and follow-up of localized plasmacytomas of the upper respiratory tract.
