Hemoglobinde Azalma ile Karakterize Bir Vaka}, journal={Ankara Üniversitesi Tıp Fakültesi Mecmuası}, volume={26}, pages={1267–1276}, year={1974}, author={Arcasoy, Ayten}, keywords={eritropoez, hemoglobin, fetal}, abstract={This paper presents a rare case of erythroleukemia marked by significantly increased fetal hemoglobin (56%) and reduced A. hemoglobin (0.25–0.26%), ultimately transitioning into acute myeloblastic leukemia. A six-year-old boy exhibited hepatosplenomegaly, severe anemia, thrombocytopenia, and 20% nucleated erythrocytes in peripheral blood. Bone marrow revealed erythroid hyperplasia; despite thalassemia-like HbF levels, the presence of leukemic blasts distinguished the diagnosis. The patient did not respond to quadruple chemotherapy and succumbed to hemorrhagic complications on the 19th day. Findings suggest that persistent fetal erythropoiesis may occur in acquired hematologic malignancies, highlighting its potential role in leukemogenesis.}, number={5-6}, publisher={Ankara University}
