Myelocytes contain both primary (azurophilic) and secondary/specific (pink or lilac) cytoplasmic granules.  The proportion of secondary granules increases as the cell matures.  The nucleus is round and lacks a nucleolus.  The chromatin is more condensed than that of a promyelocytes.  Myelocytes are not normally present in peripheral blood, but may be seen in infectious / inflammatory conditions, growth factor effect, marrow infiltration, and myeloid neoplasms.
