The category of acute erythroid leukemia was significantly revised in the recently published 2016 revision to the World Health Organization (WHO) classification of myeloid neoplasms. In the previous 2008 WHO classification, acute erythroid leukemia was categorized into two subtypes: erythroleukemia and pure erythroid leukemia (PEL), whereas in the 2016 WHO update, erythroleukemia was merged into myelodysplastic syndrome, and PEL becomes the only type of acute erythroid leukemia. PEL is a rare and aggressive form of acute leukemia whose biology remains poorly characterized. In this review, we discuss the clinicopathologic features, diagnosis, putative pathogenesis, and molecular biology of PEL, with an overview of novel concepts and future directions in this area.
