Atypical chronic myelogenous leukemia (aCML) is a leukemic disorder that exhibits both myelodysplastic and myeloproliferative features at the time of diagnosis. It is thought that these features dennote a poor prognosis. Atypical CML cases are usually BCR-ABL negative. The optimal treatment of aCML is uncertain because of the rare incidence of this chronic leukemic disorder. Treatment with hydroxyurea may lead to short-lived partial remissions of 2- to 4-months’ duration. Atypical CML, appears to respond poorly to treatment with interferon-alpha.
