Promonocytes are immature monocytic cells that have moderate amounts of blue-gray cytoplasm and fine cytoplasmic granules.  Cytoplasmic vacuoles may be present.  The nucleus is lobulated or delicately folded.  The chromatin is less condensed than that of a mature monocyte, and nucleoli may be present.  Promonocytes are considered to be blast equivalents, and are counted as blasts in peripheral blood and bone marrow differential counts.
