Howell-Jolly Bodies and Pappenheimer Bodies
This image shows Howell-Jolly bodies, indicated with single arrows, and a cluster of Pappenheimer bodies, indicated with a double arrow. If the smear was stained with Prussian blue iron stain, the Pappenheimer bodies would stain blue, indicating the presence of iron, but the Howell-Jolly bodies would not stain blue, indicating the absence of iron.
