CLPD-Nk is an extremely rare hematologic disorder. It is characterized by a persistent increase (≥2 ×109 /L, over > 6 months) of large granular lymphocytes of the NK cell type in the peripheral blood. Only a few case series have been published to date. The disease is characterized by an indolent clinical course (Kurt H et al. 2018) .
