Pelger-Huet Anomaly in a Norwegian Forest Cat

Abstract

A 9-year-old, castrated male Norwegian Forest cat was presented for a health examination. The initial complete blood cell count (CBC) revealed a degenerative left shift. The blood smear examination indicated significant nuclear hyposegmentation of the neutrophils, eosinophils, basophils, and monocytes; this observation persisted over a year. Pelger-Huet was suspected based on the results of the chemistry profile, imaging examination, microorganism test, and bone marrow examination; the diagnosis of Pelger-Huet anomaly was established in this cat.
