title: Serum ferritin and sequestered stores of body iron.
abstract: A 47-year-old man with sickle cell anemia, chronic cor pulmonale, and congestive heart failure died following a short illness. A diagnosis of iron deficiency was established during life by usually accepted criteria including a low serum ferritin concentration. Autopsy showed no stainable iron in the bone marrow, liver, and the heart. Marked deposits of iron were seen in the kidneys and the atrophic spleen. These findings suggest that the serum ferritin concentration may not reflect the metabolically sequestered stores of iron in the spleen and the kidneys.
