Figure 1: (A-B) Morphology of blasts (May-Grünwald Giemsa
stain; 1000x) and myeloperoxidase-staining (Hematoxylin counterstain) of
blasts at diagnosis and; (C-D) at day-8 post-corticosteroid
therapy. (E) Fluorescent in-situ hybridization using
dual colour break apart probe showing deletion of telomeric end (3’end;
orange) of TCF3 gene on chromosome 19p13.3 indicating unbalanced
translocation in blasts and (F) granulocytes. (G)Fluorescent in-situ hybridization using dual colour break apart
probe showing an abnormal signal pattern indicative of ZNF384translocation (DAPI counterstain).
