Hyperleukocytosis and Abnormal Complete Blood Count
Published on: May 01, 2017
A 76-year-old man with a history of bladder cancer treated with two local resections and no chemotherapy or radiation was transferred from an outside hospital with hyperleukocytosis and an abnormal complete blood count (white blood cell count, 162 cells/μ; hemoglobin 8.2 g/dL; and platelet 43 K/uL) in 2017. His medical history was significant for mild leukocytosis and skin infections in 2006. Evaluation of peripheral blood revealed leukocytosis due to neutrophilia with two distinct subsets of neutrophils (Figure). Examination of marrow also showed abnormal findings.
