==Overview==
==[[B-cell prolymphocytic leukemia overview|Overview]]==
'''B-cell prolymphocytic leukemia''' is a more aggressive but still treatable form of [[leukemia]]. The malignant [[B cells]] are larger than average.


==Pathophysiology==
==[[B-cell prolymphocytic leukemia historical perspective|Historical Perspective]]==
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===
==[[B-cell prolymphocytic leukemia classification|Classification]]==
It can involve deletions from [[chromosome 11]] and [[chromosome 13]].<ref name="pmid10720137">{{cite journal |author=Lens D, Matutes E, Catovsky D, Coignet LJ |title=Frequent deletions at 11q23 and 13q14 in B cell prolymphocytic leukemia (B-PLL) |journal=Leukemia |volume=14 |issue=3 |pages=427-30 |year=2000 |pmid=10720137 |doi=}}</ref>


===Markers===

==Prognosis==
==[[B-cell prolymphocytic leukemia causes|Causes]]==
It has a relatively poor prognosis.<ref name="pmid16642047">{{cite journal |author=Del Giudice I, Davis Z, Matutes E, ''et al'' |title=IgVH genes mutation and usage, [[ZAP-70]] and [[CD38]] expression provide new insights on B-cell prolymphocytic leukemia (B-PLL) |journal=Leukemia |volume=20 |issue=7 |pages=1231-7 |year=2006 |pmid=16642047 |doi=10.1038/sj.leu.2404238}}</ref>.
