Pelger-Huët anomaly


Pelger-Huët anomaly

(pel″gĕr hū′ĕt) [Karel Pelger, Dutch physician, 1885–1931; Gauthier Jean Huët, Dutch physician, 1879–1970] ,

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.
