n.
the developmental stage of a granulocyte (a type of white blood cell) between the myeloblast and the myelocyte. It has abundant cytoplasm that, with Romanowsky stains, appears blue with reddish granules. Promyelocytes are normally found in the blood-forming tissue of the bone marrow but may appear in the blood in a variety of diseases. See also granulopoiesis.

pro·my·elo·cyte (pro-miґə-lo-sīt) a precursor in the granulocytic series, being a cell intermediate in development between a myeloblast and myelocyte and containing a few, as yet undifferentiated, cytoplasmic granules. Called also premyelocyte and progranulocyte.
