Presentation
Hyperleukocytosis (>100 x 10(9)/L) is an uncommon presentation of chronic leukemias. It can present with a variety of symptoms secondary to leukostasis, a syndrome caused by the sludging of circulating leukemic blasts in the microvasculature. [ncbi.nlm.nih.gov]

- Anemia
Other causes of leukocytosis include medications, splenectomy, hemolytic anemia and malignancy. [aafp.org]

While the pathophysiology of leukostasis is not fully understood, recent research has elucidated many novel pathways that may have therapeutic implications in the future. [ncbi.nlm.nih.gov]

Being a medical emergency, early recognition of leukostasis and initiation of therapy prevents mortality. [ncbi.nlm.nih.gov]
