Which of the following would be an expected finding in the bone marrow in a patient with the following results: serum iron = 124 ug/dL (reference range: 35-170 ug/dL); TIBC = 284 ug/dL (reference range: 225-425 ug/dL)?

The serum iron and TIBC levels suggest that there is adequate iron available for transport and utilization by the body. Therefore, an expected finding in the bone marrow would be adequate iron stores with a positive Prussian blue stain, indicating the presence of iron-containing hemosiderin. Sea blue histiocytes are seen in conditions such as Gaucher disease and Niemann-Pick disease, and increased iron stores would not be expected in a patient with normal serum iron and TIBC levels. Decreased or absent Prussian blue specks would indicate a lack of iron-containing hemosiderin, which would not be expected in a patient with adequate iron availability.
