Abstract
Blastic crisis (BC) remains the main challenge in chronic myeloid leukemia (CML). Treatment typically involves a tyrosine kinase inhibitor (TKI) alone or in combination with polychemotherapy, followed by hematopoietic stem cell transplantation (HSCT) for eligible patients. The leukemic phenotype includes both myeloid and lymphoid lineages. Myeloid BC with megakaryocytic differentiation is rare, while differentiation to plasmacytoid dendritic cells is extremely uncommon in the literature. We present a patient with CML in megakaryoblastic blastic crisis (BC-MGK) and a case of blastic crisis with plasmacytoid dendritic cells (BC-PDC), both of whom received combined treatments with TKI and polychemotherapy with excellent outcomes despite the poor prognosis.
