Question

Quizplus · Accepted Answer

The subgroup of CLL with the listed characteristics is consistent with hairy cell leukemia, including the presence of circulating hairy cells and expression of markers such as TRAP, CD20, CD22, CD103, CD11c, and CD25. B-cell CLL would not have the characteristic circulating hairy cells, T-cell PLL and Sézary syndrome would not exhibit CD20 and CD22 expression, and CD103 expression is not typically seen in B-cell CLL or Sézary syndrome.
