Multiple myeloma is a malignant disease characterised by malignant proliferation of plasma cells of bone marrow,associated with excessive production of paraprotein .
Plasma cells produce monoclonal paraprotein,which may be associated with the excretion of light chain in urine,called Bence-Jonses protein,either kappa or lambda.In some cases,there is no paraprotein,only light chain in urine.👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️👩⚕️
