Final answer:
The characteristic cell type of Pelger Huet anomaly is neutrophils. These are granulocytes with typically lobed nuclei, and in this genetic condition, the lobation is reduced, leading to hyposegmented neutrophils.
Step-by-step explanation:
The cell type characteristic of Pelger Huet anomaly is neutrophils. Pelger Huet anomaly is a genetic condition characterized by the presence of hyposegmented neutrophils. Neutrophils are a type of granulocyte, which are cells with a lobed nucleus and granular inclusions in the cytoplasm. Neutrophils are typically part of the immune system's first response to injury or infection. In Pelger Huet anomaly, the affected neutrophils have fewer lobes than normal, typically presenting with a bilobed nucleus, which distinguishes them from other white blood cells such as lymphocytes, monocytes, and eosinophils.
It is important to correctly identify neutrophils when studying blood cell morphology, as they play a critical role in the body's defense mechanisms. Their distinct lobed nucleus can have two to five lobes; however, in Pelger Huet anomaly, this lobation is reduced.
