Popis: BACKGROUND: Childhood acute lymphoblastic leukemia (ALL) is the most prevalent malignant disease (25%–30%) and the most common type of leukemia (75%–80%) among children. It is not a single disease with significant phenotypic and genotypic variability that has diagnostic and prognostic implications. This study aims to provide the immunophenotypic profile of childhood ALL in Iraqi patients and to explore the frequency of aberrant myeloid antigen expression and their association with hematological parameters. PATIENTS, MATERIALS AND METHODS: The records of 67 pediatric patients diagnosed as ALL were reviewed for their flow cytometric immunophenotyping results at presentation. RESULTS: B-ALL constituted 76.1% of the cases and 23.9% were T-ALL. There was a highly significant statistical relation between higher age interval and T-ALL phenotypes (P = 0.001). Higher hemoglobin (Hb) level and white blood cell count were significantly related with T-ALL subtype (P = 0.039 and < 0.001, respectively). CD34, HLA-DR, CD10, and CD79a were significantly correlated with B-ALL compared to T-ALL (P = 0.007,
