Abstract:
Four cases of atypical chronic myeloid leukemia (aCML), which were compatible with the FAB guideline for the classification of chronic myeloid leukemia (CML), are presented. All 4 patients showed the onset in old age, leukocytosis with an increase in the number of immature granulo-cytes, monocytosis, a low basophil count, and a dysgranulopoiesis in the peripheral blood, a nega-tivity of the bcr-abl gene rearrangement, and a hypercellular marrow with marked granulocytic hyperplasia and dyshemopoietic features. Two patients died within 3 months and the other 2 are currently under observation after a partial response to hydroxyurea. aCML is known to have a poor therapeutic response and outcome without a blastic crisis. A greater deal of concern regarding aCML is required for an accurate diagnosis and classification.
