A case of non-producer multiple myeloma (MM) is described and compared with the previous reports. Some recurrent clinical traits seem to characterize this disease. It is interesting that reported cases seem to show a low aggressivity. Some biological problems connected with this form of disease are discussed.

The non-producer plasma cell myeloma. Report of a case and review of the literature.

Less than one per cent of all patients with multiple myeloma fail to show a serum and/or urinary paraprotein. We report here the clinical and laboratory features of a patient with this disorder.
