The pure erythroleukemia: a case report and literature review.

Pure acute erythroleukemia is a rare form of acute myeloid leukemia (AML) with predominant erythroid lineage proliferation. It is a heterogeneous entity amongst AML that can occur at any age, including childhood, and comprises less than 5% of AML. Di Guglielmo reported the original case of acute erythroleukemia in 1917; he described it as a syndrome composed of immature erythroid and myeloid elements characterized by a pure normoblastic proliferation.1,2
