Individuals with this inherited form exhibit the characteristic hyposegmentation in all neutrophils, as well as in eosinophils and monocytes. Understanding the Nuclear Segmentation To appreciate the Pelger-Huet anomaly, one must first understand normal neutrophil development.
Pelger-Huet Anomaly Autosomal Dominant Trait Genetics and Neutrophil Nuclear Segmentation
Feature Pelger-Huet Anomaly Normal Neutrophil Nuclear Shape Bilobed or round (pince-nez) Multi-lobed (2-5 segments) Chromatin Pattern Coarse and clumped Fine and lace-like Eosinophils/Monocytes Often affected (bilobed nuclei) Normal segmentation Clinical Significance Benign inherited trait Standard morphology Laboratory reports for this anomaly will specifically note the presence of these hyposegmented neutrophils, and it is crucial for the interpreting physician to correlate these findings with the patient’s clinical history. The table below summarizes the key cellular features observed in the hereditary form, which helps differentiate it from malignant conditions that might present with similar morphology.
Despite this unusual shape, the cells retain their ability to phagocytose pathogens, demonstrating that the anomaly is primarily a cosmetic change at the nuclear level rather than a functional defect. For this reason, the hereditary form is generally considered a benign variant rather than a disease, standing in stark contrast to the acquired forms that may arise due to underlying medical conditions.

Clinical Significance and Management. This morphological feature is most often an inherited trait, passed down in an autosomal dominant pattern, and typically does not interfere with the cell’s function.
