Acute erythroid leukemia is characterized by a predominant erythroid population in the bone marrow. There are two subtypes of this disease: erythroid leukemia (erythroid/myeloid) and pure erythroid leukemia. Erythroleukemia also shows the presence of a significant myeloid component.
Erythroleukemia is predominantly a disease of adults. Pure erythroid leukemia is very rare and may occur at any age including children.
