Peripheral smear shows four different leukocytes: a band form, a lymphocyte, a monocyte, and a metamyelocyte. The lymphocyte is a small cell with a heavily stained condensed nucleus and a small rim of blue cytoplasm. The monocyte has an irregular nucleus with grayish, blue cytoplasm that has few granules. The metamyelocyte has a kidney bean-shaped nucleus with a granulated cytoplasm.
