How would you qualify and treat a patient with neutropenia, anemia, and abnormal NK cell population with normal trilineage marrow maturation?

I would run a molecular test to confirm that the clonality does not show a CD8-positive clone, as that is more common in LGL. The findings of a clonal NK population by flow cytometry would be enough, in the setting of neutropenia and anemia, to consider a diagnosis of NK cell LGL.
