Clinical Significance and Management. Diagnostic Features and Laboratory Findings Diagnosis of the Pelger-Huet anomaly relies heavily on the visual examination of a peripheral blood smear under a microscope.

In these cases, the hyposegmentation is present only in the peripheral blood and usually resolves once the underlying condition is treated, making it a temporary hematologic sign rather than a permanent genetic trait. The hereditary variant is a benign, autosomal dominant trait caused by mutations affecting the lamin B receptor (LBR) gene.
Misdiagnosis as a myelodysplastic syndrome is a potential pitfall, which is why a thorough review of the blood film and family history is essential before rendering a final conclusion. 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. Conversely, the acquired form is a reactive phenomenon often triggered by severe infections, chemotherapy, or bone marrow disorders.
