RESUMO
Objective To investigate the diagnostic significance of synchronous observation on bone marrow biopsy,bone marrow smear and peripheral blood smear in stubborn hematonosis.Methods Thirty-seven patients with difficult and complicated hematologic diseases were detected by peripheral blood smear,bone marrow smear and bone marrow biopsy.Those slides and smears were observed.Results The 37 cases with blood disease was diagnosed of aplastic anemia in 3 cases,5 cases of myelodysplastic syndrome,6 cases of primary myelofibrosis,13 cases of secondary myelofibrosis,7 cases of lymphoma with bone marrow infiltration and 3 cases of metastatic carcinoma of bone marrow.In the diagnosis of aplastic anemia,myelodysplastic syndrome,primary and secondary myelofibrosis,lymphoma and metastatic carcinoma of bone marrow diagnosis,bone marrow biopsy is superior to smear.Conclusion Bone marrow biopsy,bone marrow smear and peripheral blood smear synchronous observation can effectively increase the diagnostic rate,decrease misdiagnosis rate,and correctly identify the stage of the disease.
