Figure 1 Bone marrow aspirate smear showing cytoplasmic vacuolization characteristic of copper deficiencyWright-Giemsa-stained bone marrow aspirate demonstrating cytoplasmic vacuolization in erythroid and myeloid precursor cells (arrows). These vacuolated precursors reflect impaired maturation associated with copper deficiency and can mimic morphologic features observed in myelodysplastic syndrome. Arrows indicate representative erythroid precursors with prominent cytoplasmic vacuoles. Original magnification ×1000 (oil immersion; scale bar, 20 μm).
