Hemosiderin  It is hemoglobin derived, golden yellow to brown, granular or crystalline pigment in which form iron is stored in cells.

Under normal conditions small amounts of hemosiderin can be seen in the mononuclear phagocytes of the bone marrow, spleen and liver, all actively engaged in red cell breakdown
