Abstract:
Objective To investigate the characteristics of dysplasia in myeledysplastic syndrome (MDS). Methods 716 samples of adult patients with abnormal blood routine and unelear cause were collected between July 04, 2003 and March 14, 2007. Based on the gold diagnostic standard of WHO MDS classification, all eases were detected on cytomorphology, cytochemical stain, bone marrow pathological assay,cytogenetics, flow eytometry et al. The cytological study of bone marrow on some abnormal hematopaietie cells has a diagnostic value to determine clonal or non-clonal diseases and assess sensitivity and specificity. Results in the complicated various dysplasia of hematopeiefic ceils, the following characteristics can be the main basis of cytomorphological diagnosis: one of granular Auer bodies, micronuclens (MN), or nuclear budding, erythroid nuclear budding, megakaryocytes presented in peripheral blood, myeloblast or prorubricyte exhibited in peripheral blood, ringed sideroblasts>1%. The subordinate basis of cytomorphological diagnosis development of nuclei, ring-shaped nuclei, and aggregation of nuclear chromafin, erythroid multi-nuclei, odd nucleus, mother-daughter nucleus, nuclear fragmentation, vacuole, anisoeytosis and mieromegakaryocytes.Conclusion Cytomorphologic assay is the base for the diagnosis of MDS, however, it presents certain limit,especially when eytomnrphoiogical change does not possess specificity for early MDS. Hereby, it requires to combine other deteetion methods.
