Chronic Lymphocytic Leukemia

"Copycat": MCL with CD5+/partial CD23+

October 2008
This slide points out the caution with which one needs to interpret flow findings. In this case of a mantle cell lymphoma, one clearly sees the bright CD20 expression with dual expression of CD5. It might also be easy for one to assume that this case is CD23 positive but note that the expression of CD23 is what I would call partial and is not characteristic of what one sees in a typical case of CLL but indeed is actually a common finding in mantel cell lymphoma.
