PHA

A benign autosomal dominant disorder of neutrophil maturation, in which granulocytes form with rodlike, dumbbell, peanut-shaped, and spectacle-like nuclei. The chromatin of the nuclei is unusually coarse. Despite their unusual shape, the oddly formed cells function normally. An anomaly in white blood cell formation called Pseudo-PHA or acquired PHA appears structurally similar to PHA and occurs in myelodysplasia and some leukemias.

Pelger-Huët anomaly

an anomaly, probably inherited, of neutrophils and eosinophils in which there is hyposegmentation of the nuclei. Seen rarely in dogs and cats with no clinical significance.

pseudo-Pelger-Huët anomaly-H. a
a transient hyposegmentation in neutrophils and eosinophils, usually from unknown causes. May be mistaken as the congenital anomaly.
