What do you call erythrocytes containing iron granules when stained with Prussian blue?

Erythrocytes that contain iron granules when stained with Prussian blue are referred to as siderocytes. This term is specifically used in hematology to describe red blood cells that have visible iron deposits, which can indicate conditions such as sideroblastic anemia or iron overload states. The presence of iron granules within the erythrocytes can be visualized using the Prussian blue stain, which reacts with the iron to produce a blue coloration, making it easier to identify these cells under a microscope. This characteristic helps in diagnosing various hematological disorders related to iron metabolism and storage.
