Pseudo-Chediak-Higashi Anomaly in Promyelocytic Leukaemia Associated with Intravascular Coagulation

Abstract
Giant granules were present in the cytoplasm of marrow granulocytes and in abnormal immature leukocytes circulating in the blood of a patient with promyelocytic leukemia associated with intravascular coagulation. These granules resembled those seen in Chediak-Higashi syndrome.
