Bone marrow aspiration of the right posterior superior iliac crest resulted in a 'dry tap' and a bone marrow biopsy showed an infiltration of 95% blasts morphologically lymphoid in nature (Figures 1 and 2).
Magnification x 400 showing blasts with an undifferentiated appearance and some with vacuoles.
