B-cell prolymphocytic leukemia pathophysiology
Pathophysiology
It is postulated that the originating cell line for this disease is a mature B-cell. Due to the systemic nature of this disease, leukemic cells can be found in peripheral blood, lymph nodes, bone marrow, spleen, liver, skin.
Genetics
It can involve deletions from chromosome 11 and chromosome 13.[1]
Markers
- A case has been described as CD20+, CD22+, and CD5-.[2]
- It can also be CD5+.[3]
- Another case was described as CD45+, CD19+, CD20+, CD5+, HLA-DR+, CD10-, CD23+/-, CD38+ and FMC7-.[4]
