In the 2008 WHO classification Acute Erythroid leukemia (AEL) was classified into two subtypes, one subtype was Erythroleukemia and second subtype was pure erythroid leukemia (PEL). However, in the 2016 WHO update, erythroleukemia was merged into myelodysplastic syndrome, and PEL was described as the only subtype of AEL [1-12]. PEL is a rare form of acute leukemia with an aggressive clinical course and is characterized by an uncontrolled proliferation of immature erythroid precursors (proerythroblastic or undifferentiated) [1-12].
