Abstract
Pure erythroid leukemia (PEL) is rare hematopoietic neoplasm characterized by uncontrolled proliferation of immature erythroid precursors—mainly abnormal proerythroblasts—comprising at least 80% of bone marrow cells. In this paper, I present a case of 48 years old patient, who presented with pancytopenia and circulating erythroblast in peripheral blood after long history of alcohol abuse. Bone marrow examination revealed hypercellular marrow which is markedly infiltrated with immature erythroid precursors. An expanded panel of immunophenotyping markers has confirmed the diagnosis of PEL. Cytogenetics analysis detected a complex karyotype with multiple chromosomal abnormalities and a novel translocation, t(8;9) (p11.2;q12), which has not been reported in acute myeloid leukemia (AML) in the past. The patient was treated with standard AML chemotherapy but he did not show an optimal response and passed away. An updated and short review about various aspects of PEL has been made with special focus on immunophenotyping and genetic studies.This publication has 26 references indexed in Scilit:
