Aggressive natural killer cell leukemia
Alerts and Notices
Synopsis

ANKL is almost always associated with Epstein-Barr virus (EBV) infection. Hemophagocytic lymphohistiocytosis (HLH) is reported in 60% of cases.
The main sites of involvement include the liver and spleen, the bone marrow and peripheral blood, and, less frequently, the nose and skin. Clinically, these patients commonly present with fever and liver dysfunction with a rapidly progressive course.
ANKL has high mortality (median length of survival is approximately 8 weeks).
