A promyelocyte (or progranulocyte) is a granulocyte precursor, developing from the myeloblast and developing into the myelocyte. Promyelocytes measure 12-20 microns in diameter. The nucleus of a promyelocyte is approximately the same size as a myeloblast but their cytoplasm is much more abundant.[1] They also have less prominent nucleoli than myeloblasts and their chromatin is more coarse and clumped.[1] The cytoplasm is basophilic and contains primary red/purple granules.[1]
