A Stimulating Case of Leukocytosis
Published on: November 01, 2016
A 68-year-old woman with a history of chronic leukocytosis was referred for a second opinion. She has no significant past medical history. She has smoked a pack of cigarettes weekly for the past 30 years. She initially presented with a mild neutrophilic leukocytosis, which has been slowly progressive throughout the past 17 years (WBC 13.3-32.7 × 109/L; absolute neutrophil count 26.5 × 109/L at the time of referral). The hemoglobin and platelet count are normal. She has remained asymptomatic during this period and does not have palpable lymphadenopathy or hepatosplenomegaly on examination. A peripheral blood smear is shown below.
