Acquired Pelger-Huet anomaly associated with Mycoplasma pneumoniae pneumonia.
A case report of a healthy 33-year-old man with Mycoplasma pneumoniae pneumonia who concomitantly had the acquired Pelger-Huet anomaly develop is presented. Up to 31% of his total white blood cell count was comprised of Pelger-Huet cells at the height of his clinical illness. The Pelger-Huet cell count returned to 0% after doxycycline therapy and resolution of the pneumonia. No other explanation for the Pelger-Huet anomaly could be determined. A review of the pertinent hematologic literature is included.
