Marrow iron.
Marrow aspirates stained with the Prussian blue reaction give a variety of patterns. Characteristic pictures are shown for megaloblastic anemia, infection, and subjects after injection of iron dextran. The appearance of iron in histiocytes in marrows stained with Wright's stain is differentiated from noniron deposits. A graph shows the relative distribution of iron in RBCs and storage in different clinical situations.
