This bone marrow smear was obtained from yet another patient with MM. The plasma cells have little resemblance to normal plasma cells. The chromatin is smooth and homogeneous. The nuclei are large for the total cell area. The nuclei take up so much of the total cell area that there is only a slight tendency for them to be eccentric. Cells like these may be mistaken for blasts other than plasmablasts.
