Typical blood findings inαthalassemia myelodysplasia syndrome (ATMDS).
A. A peripheral blood smear (May-Grünwald-Giemsa, ×400) from an untransfused patient. Many red cells are hypochromic and/or microcytic, while others appear relatively normal and well-preserved, presumably the descendants of non-thalassemic clones.
B. Classic hemoglobin H inclusions (HbH) in an ATMDS patient seen after supravital staining (Brilliant cresyl blue, ×400).
