Characteristic CD103 and CD123 Expression Pattern Defines Hairy Cell Leukemia

Induction of features characteristic of hairy cell leukemia in chronic lymphocytic leukemia and prolymphocytic leukemia cells.

In vitro maturation was induced with 12-O-tetradecanoylphorbol-13-acetate in leukemic cell samples from patients with chronic lymphocytic leukemia (n = 10) and prolymphocytic leukemia (n = 4). The cells were studied for morphology, for immunological markers using the fluorescence activated cell sorter, and for acid phosphatase isoenzymes using both cytochemistry and isoelectrofocusing. Morpholo...

Immunophenotypic analysis of CD103+ B-lymphoproliferative disorders: hairy cell leukemia and its mimics.

CD103 is characteristically expressed in hairy cell leukemia (HCL), a B-lymphoproliferative disorder highly responsive to treatment with purine analogs. Other CD103+ diseases are rare and do not respond well to the same therapy, including HCL variant (HCLv) and splenic marginal zone B-cell lymphoma (SMZL) variants. We analyzed 215 cases of CD103+ B-lymphoproliferative disorders to further delin...

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...

Hairy Cell Leukemia in a Young Male: An Unusual Presentation

Dear Editor-in-Chief A 28 yr male was presented in October 2015 at Medicine Outpatient Department, Safdarjung Hospital, New Delhi- India with generalized weakness, fever and cough for preceding 15 days. Clinicoradiologic examination revealed pallor, firm, non-tender splenomegaly measuring 13.7 cm and hepatomegaly (liver span - 16.9 cm). However, no lymphadenopathy was found.
