A benign condition has the following characteristics: WBC count of 45 × 10⁹/L with a left shift and normal RBC count. What is this condition? A) Leukoerythroblastosis B) Pelger-Huët anomaly C) Leukemoid reaction D) Pyknosis

Question

Quizplus · Accepted Answer

The high WBC count with left shift and no evidence of anemia or other cytopenias is consistent with a leukemoid reaction, which is a reactive process caused by infection, inflammation, or other non-neoplastic conditions. Leukoerythroblastosis would present with immature cells such as nucleated RBCs and myelocytes, and Pelger-Huët anomaly is a genetic disorder that results in hyposegmentation of neutrophils, which would not cause a left shift. Pyknosis is a process of nuclear condensation that occurs during apoptosis and is not related to this scenario.
