This mature neutrophil has a single nuclear lobe. The nuclear chromatin is dense. Cells such as this and the previously shown bilobed "pince-nez" form may be seen with inherited Pelger-Huet or acquired pseudo Pelger-Huet.
*Note: When examining a slide made from an EDTA tube of normal blood, an occasional cell containing a round pyknotic nucleus and neutrophilic-appearing cytoplasm may be seen. Rare cells such as these do not indicate the presence of Pelger-Huet anomaly.
