Abstract
The phagocytosis of erythrocytes by leukemic blasts is a rare finding in acute myeloid leukemia and has been reported most commonly in monocytic and megakaryocytic morphologies. In the reported cases, erythrophagocytosis by leukemic blasts has been associated with t(8;16). This translocation is associated with a poor outcome independent of erythrophagocytosis. There has only been one reported case of erythrophagocytosis by leukemic blasts occurring in a patient with a normal karyotype. We report a 62-year-old woman with acute myeloid leukemia with monocytic features and a normal karyotype noted to have erythrophagocytosis by leukemic blasts.
