WebAs previously discussed, MDS is a clonal disorder that results in defective cell maturation and results in dysplastic changes. The dysplasia can be seen in both the peripheral blood and in the bone marrow. Dysplasia may be seen in one or more cell lines, and the types of dysplasia seen vary. WebMegaloblasts are large nucleated red blood cell precursors with noncondensed chromatin. The most common causes of megaloblastic, macrocytic anemia are deficiency or defective utilization of vitamin B12 or folate. Do complete blood count, red blood cell indices, reticulocyte count, and peripheral smear.
