    【Abstract】 Objective To summarize the clinical characteristics of pure megakaryocytic aplasia to improve diagnosis and treatment.Methods Blood conventional analysis was performed and cells were classified after bone marrow smears were stained by Wright’s staining in 7 patients with pure megakaryocytic aplasia.Results The bone marrow smears didn’t show any megakaryocyte or marked decrease of megakaryocyte ; The blood platelet counts were below 48×10⁹/L with an average of 22×10⁹/L; Severe hemorrhagic symptoms appeared with various degrees of anemia in all patients and hepatomegaly and splenomegaly were observed in a few patients.After treatment,3 patients recovered,2 patient died,and no improvement was seen in 2.Conclusion The clinical and hematological manifestations of pure megakaryocytic aplasia are similar to primary thrombocytopenic purpura,and differential diagnosis of the two will contribute to better clinical treatment and turnover of symptoms. ......
