To analyze the correlation between dysplastic lineage and type of cytopenia in myelodysplastic syndromes.


We analyzed the correlation between dysplasia and cell count using the data set of our previous morphologic study.


There were no correlations between dysgranulopoiesis of 10% or more and absolute neutrophil count (ANC). Similarly, hyposegmented mature neutrophils (Pelger) of 10% or more were not related to ANC. Interestingly, the platelet count of patients with dysmegakaryopoiesis (dys Mgk) was higher than that of patients without dys Mgk (dys Mgk ≥10% vs <10%, P = .08; dys Mgk ≥40% vs <40%, P = .02; micromegakaryocytes ≥10% vs <10%, P = .004).


Since low cell counts did not correlate with the presence of dysplastic features, we suggest that dysplastic features do not directly relate to apoptosis.
