Our patient met the criteria for a definite diagnosis of myeloma: her bone marrow plasma cell count was increased (9% of the myelogram) which approaches the lower limits for myeloma (10%); the serum protein quantification and immunofixation showed an increased level of IgG kappa monoclonal protein (M-protein); the presence of an extramedullary myeloma tumour; and she had a normocytic normochromic anemia associated with decrease in bone marrow erythropoiesis. The gene discussed is MYOM2; the disease is anemia.
