Overview

  • MGUS and smouldering myeloma by definition do not manifest clinically. Multiple myeloma presents classically with hypercalcaemia, renal dysfunction, anaemia and lytic bony lesions (denoted by the acronym CRAB); myeloma should be suspected in patients with any of these manifestations without any other clear cause.
