Which anomaly is defined by bilobed neutrophils?

Bilobed neutrophils reflect a hyposegmentation pattern where the nucleus appears in two lobes instead of the normal multi-lobed segmentation. This morphology is classically associated with Pelger-Huët-type changes. The acquired form that mimics the congenital Pelger-Huët feature—often seen in myelodysplastic syndromes or after certain drugs—is the pseudo-Pelger-Huët anomaly. So, when the prompt points to an anomaly defined by bilobed neutrophils, the best match among the options is the pseudo-Pelger-Huët anomaly, since it specifically denotes this bilobed neutrophil appearance in an acquired context. The other conditions have distinct hallmark features: May-Hegglin shows giant platelets with Dohle-like inclusions in neutrophils, Alder-Reilly presents with coarse granules in leukocytes, and Chediak-Higashi involves giant lysosomal granules in multiple cells and oculocutaneous albinism.
