The bone marrow studies of 13 children with myelodysplastic syndrome(MDS)

Objective:Discussing the laboratory findings and clinical features of the children with MDS.Methods:Analysing the results of peripheral blood,bone marrow and clinical manifestations in 13 patients with MDS.Results:All 13 patients were male.Main clinical manifestations include fever,anemia and hepatosplenomegaly.The anemia was of moderate to severe degree.Immature RBC were found in the peripheral blood smears.WBC ranged from high,normal or low.Immature peripheral blood cells were seen in 4 patients.The counts of platelets were normal or low.The bone marrow showed hyperplasia actively and abnormal erythropoiesis and/or myelopoiesis.The diagnosis in 10 patients was RA,2 patients,RAEB and 1 patient,RAEB-t.Conclusion:The diagnosis of MDS depends on the bone marrow examination.The bone marrow shows one abnormal hematopoietic system at least and must differentiate with other hematologic disorders.
