On page 1917, in the first box on the right side of Figure 4, the phenotype of NK-LGL leukemia should be CD3negCD56pos/CD16pos, not CD3posCD56pos/CD16pos. The corrected Figure 4 is shown below.

Figure 4.

Diagnosis algorithm of LGLL. NK clonality score based on 4 parameters: NK cell count of >11 × 109/L: 2 points; KIR restricted phenotype: 2 points; CD94 or NKG2Ahi: 1 point; STAT3, STAT5B, TET2, or TNFAIP3 mutation: 2 points.38
