Multiple myeloma without detectable Ig synthesis.
A case of nonproductor myeloma is reported. The diagnosis was supported by the radiological findings, the heavy marrow infiltration of malignant plasma cells, the absence of a monoclonal component in the serum or urine and the failure to demonstrate intracytoplasmic immunoglobulins with immunoifluorescent techniques. The clinical findings of our patient are similar to those reported for the 5 cases of nonproductor myeloma described so far, indicating that there are no characteristic features differentiating nonproductor myeloma from productor myelomas.
