label_lc: non-secretory multiple myeloma
description: "A rare type of multiple myeloma in which the plasma cells synthesize but do not secrete immunoglobulins.  As a result, none of the immunoglobulins appear out of the normal range.  The symptoms are generally the same with those of immunoglobulin-secreting myeloma; however, the incidence of renal insufficiency is lower in non-secretory myeloma.  The diagnosis can be missed because of the absence of monoclonal immunoglobulin in the serum or urine."
