Chronic Myeloid Leukaemia (CML) is rare in young patients. Out of 93 cases diagnosed as CML, 11 patients were under the age of twenty years (11.8%). Nine of them showed typical features of ACML while two children less than 6 years old showed features of JMML. This study compares the two groups of patients in terms of clinical features, peripheral blood and bone marrow findings. Patients with ACML had a mean age of 10.5 years against the mean of 4 years for JMML patients. ACML showed a female predominance while both patients of JMML were male children. patients in both groups presented with organomegaly but JMML patients exhibited a more aggressive clinical course and expired two and ten months after diagnosis. The peripheral blood showed an elevated WBC count in both groups. The platelet count was normal in most patients of ACML while it was reduced in one and increased in the second patient of JMML. The diagnosis of JMML was based on the findings of absolute monocytosis, reduced or absent megakaryocytes and absence of micromegakaryocytes.
