Abstract:
Precursor Natural Killer (NK) cell lymphoblastic leukemia/lymphoma is a rare entity defined clearly by WHO (2008 WHO classification). However, the pathobiology of this subset of neoplasms is not clearly defined. There is wide disparity in the literature regarding the nomenclature and diagnostic criteria used to diagnose and characterize acute leukemias of presumed NK cell origin. In the present article we report a case of Precursor NK cell lymphoblastic leukemia/lymphoma and review the cases reported after 2008 WHO classification came into vogue, as acute leukemias of NK cell origin.
