Hairy cell leukemia – immunotargets and therapies

Hairy cell leukemia (HCL) is an indolent low-grade B-cell lymphoproliferative disorder that is reasonably sensitive to standard first-line purine analog therapy. However, in many cases, repeat relapses occur, requiring multiple courses of purine analog therapy, promoting eventual drug resistance. This, coupled with the concerning side effects of repeated purine analog exposure, has prompted the...

Hairy cell leukemia-variant.

Hairy cell leukaemia variant is a very rare chronic lymphoproliferative disorder and is closely related to hairy cell leukemia. We hereby describe a case of hairy cell leukaemia variant for the first time in Saudi Arabia. An elderly Saudi man presented with pallor, massive splenomegaly, and moderate hepatomegaly. Hemoglobin was 7.7 g/dl, Platelets were 134 x109/l and white blood count was 140x1...

Case 4: Hairy Cell Leukemia

Hairy Cell Leukemia (HCL) and Hairy Cell Leukemia Variant (HCL-V)

Cells from hairy cell leukemia (HCL) and hairy cell leukemia variant (HCL-V) have a distinct immunophenotype which is of a mature but not terminally differentiated activated B-cell. Although some similarities exist between these two conditions like the expression of B-cell activation marker CD103, CD11c and IgG heavy chain expression, differences exists between these two diseases. HCL is positi...
