title: Agnogenic myeloid metaplasia preceded by repeated leukemoid reactions and persistent acquired Pelger-Huët anomaly of granulocytes: case report with review of acquired Pelger-Huët anomaly.
abstract: A case report of agnogenic myeloid metaplasia (AMM) is presented in which a patient had a preliminary 18-month period characterized by leukemoid reactions to repeated infections alternating with normal health, throughout which an acquired Pelger-Huët anomaly persisted. This is the only reported case of the anomaly as a premonitory hematologic marker of AMM. The literature concerning the acquired Pelger-Hut anomaly is reviewed.
