B-cell prolymphocytic leukemia is a more aggressive, but still treatable, form of chronic lymphocytic leukemia. The malignant B cells are larger than average. The name is commonly abbreviated B-PLL.
It can involve deletions from chromosome 11 and chromosome 13.[1]
It has a relatively poor prognosis.[2]
A case has been described as CD20+, CD22+, and CD5-.[3]
