Bone marrow smears (×400, panoptical staining) showing several erythroblasts in different maturation phases with clear dyserythropoietic features (maturative asynchronism, cytoplasmic blebs). (A) A bone marrow smear revealed megaloblastoid proerythroblasts with polychromatophilic cytoplasm, multiple cytoplasmic blebs, and polylobated hyperdiploid nucleus with finely dense chromatin. (B) A bone marrow smear revealed giant proerythroblast with scarce basophilic cytoplasm and round nucleus with immature chromatin.
