Figure legends:
Figure 1: (A)Wright-Giemsa stained of bone marrow aspirate smear showing intact hematopoiesis with plasmacytosis (white arrows) (50x). Plasma cells are highlighted by CD138 IHC 40x magnification (B). The plasma cells are polytypic for Kappa-IHC (C) and Lambda-IHC (D), 40x magnification.
Figure 2 : Slides from the trephine bone marrow core biopsy (case 1). (A) 40x magnification of H&E demonstrating increased lymphoblasts as noted by yellow arrows 100x oil immersion magnification (B). (C) Flow cytometry images showing the blasts are CD45 dim, expressing CD19, CD10 and TDT. Peripheral blood and bone marrow of case 2. (D) peripheral blood smear 40X showing pancytopenia with circulating blasts. (E) touch prep 40x showing increased sheets of blasts highlighted by Pax-5 (F) 40X and TDT (G) 40X.
