Core Tip

Core Tip: Physiological leukocytosis often occurs and is mainly associated with increased neutrophil levels. We present the case of a Chinese woman in her 27th wk of gestation who had the complication of leukocytosis with a white blood cell count above 20 × 109/L for 13 wk. One day after a cesarean section, the patient’s neutrophil levels returned to normal. After 2 years of follow-up, the patient and baby were found to be healthy. During pregnancy, asymptomatic leukocytosis appears to be related to immunoregulation and termination of pregnancy may be an effective treatment approach in pregnancies with malignant leukocytosis.
