A case of acute myelomonocytic leukemia morphologically mimicking lymphoblastic leukemia

Abstract

Abstract We present the case of a 70‐year‐old man diagnosed with acute myelomonocytic leukemia, albeit that his leukemic blasts at initial presentation had scant cytoplasm, inconspicuous cytoplasmic granules, and morphologically mimicked lymphoblasts. We would like to raise the recognition that acute myelomonocytic leukemia can actually present with atypical blast morphology.
