What are Pseudo Pelger-Huet cells?

Psuedo Pelger-Huet cells have the morphological characterization of Neutrophils with hypolobation [hypo-segmented].

It can be a benign inherited defect (1/6000) of terminal Neutrophil differentiation due lamin B receptor gene mutations.

Or it can be seen in different pathological states like Myelodysplastic syndrome or CML, as well as with certain infections and drugs
