B-cell prolymphocytic leukemia is a more aggressive, but still treatable, form of 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 been suggested that some cases may represent a variant of mantle cell lymphoma.[2]
It has a relatively poor prognosis.[3]
Markers
A case has been described as CD20+, CD22+, and CD5-.[4]
It can also be CD5+.[5]
Another case was described as CD45+, CD19+, CD20+, CD5+, HLA-DR+, CD10-, CD23+/-, CD38+ and FMC7-.[6]
Treatment
Splenic irradiation has been used in the treatment.[7]
