Morphologic and immunophenotypic findings. A) At presentation, there was granulocytic predominance with progressive maturation and no significant increase in blasts or monocytes. The core biopsy shows hypercellular bone marrow with left-shifted granulocytic predominance. Flow cytometry reveals granulocytic predominance (in green) but no significant increase in monocytes (in blue) or myeloblasts (in red). B) At follow-up, the morphologic and immunophenotypic findings are similar to those at presentation.

Bone marrow morphologic and flow cytometric examinations revealed hypercellular bone marrow with granulocytic predominance with left-shifted and unusual maturation, and occasional atypical granulocytes and megakaryocytes, but no significant increase in monocytes or myeloblasts (Figure 1).
