PELGER HU T ANOMALYP elger Hu t anomaly is a rare benign autosomal dominant disorder characterized by defective nuclear segmentation (hypo-segmentation of the nucleus in neutrophils (Figure 5). Nuclei are bi-lobed, dumbbell-shaped or do not have lobes at all. It is important to differentiate from the acquired hypo-segmentation of the neutrophil nucleus, also called pseudo-Pelger Hu t anomaly, which has been observed in sepsis, myelodysplastic syndromes, hematological malignancies and in patients on certain transplant medications or other drugs.)

Neutrophil nuclear hypersegmentation is the presence of more than five nuclear lobes in the neutrophils (Figure 6). The presence of hypersegmented neutrophils is a sensitive and specific sign of megaloblastic anemia, associated with vitamin B 12 or …
