Beautiful blood cell cookies by Kristine Krafts
Here we have a neutrophilic leukocytosis with a left shift (there’s a myelocyte, top left, a metamyelocyte, bottom left, and a promyelocyte, center) and a basophilia (right). Check out how mature the chromatin is in the myelocyte, metamyelocyte, and segmented neutrophil – but how fine it is (you can even see nucleoli!) in the promyelocyte). Also, the granules in the promyelocyte are in the cytoplasm and over the nucleus as well. The basophil granules are kinda obscuring the nucleus, but that’s what happens in real life, so we’ll call it artistic rendering.
