Answer

Rare causes of anemia due to a hypoplastic bone marrow include familial disorders and the acquired pure red cell aplasias. The latter are characterized by a virtual absence of erythroid precursors in the bone marrow, with normal numbers of granulocytic precursors and megakaryocytes. Rare causes of diminished erythrocyte production with hyperplastic bone marrow include hereditary orotic aminoaciduria and erythremic myelosis.
