Laboratory Diagnosis of Bence Jones Proteinuria in a Patient with Plasma Cell Leukemia

[摘要] Kappa Bence Jones proteinuria was found by immunoelectrophoretic techniques in a patient with plasma cell leukemia, who presented with no M-proteins either in serum or urine. However, a significant decrease in normal immunoglobulins was observed. On microscopic examination of kidney sections obtained at autopsy, protein casts were seen in the distal tubules. Bence Jones protein was not detected by the conventional heat test
