Hypersegmented neutrophil
Hypersegmented neutrophil
A Hypersegmented neutrophil (pronunciation: hi-per-seg-ment-ed noo-troh-fil) is a type of white blood cell that has an abnormally large number of segments in its nucleus. It is often associated with certain types of anemia, particularly megaloblastic anemia and vitamin B12 deficiency.
Etymology
The term "hypersegmented neutrophil" is derived from the Greek words "hyper" (meaning over or above), "segment" (meaning part or section), and "neutrophil" (a type of white blood cell). The term thus refers to a neutrophil with an excessive number of segments in its nucleus.
