Abstract

Background : Hairy cell leukemia is a rare lymphoproliferative disorder.
Aim : with cytological and immunophenotypic features.
Methods : We report 6 cases of hairy cell leukemia diagnosed in the Biological Department of Hematology at the Aziza Othmana Hospital of Tunis.
Results : Hairy cells was observed in blood smears of 5 cases. Flow cytometry analysis shown monoclonal a monoclonal population B while gatinting on the expression of the CD19 and SSC signal. The positivity of the CD103 is noted in 5 cases and the CD11c signal is intense in all the cases.
Conclusion : Immunophenotype is of great interest in the diagnosis of hairy cell leukemia.

Keywords:

Hairy cell leukemia, Flow cytometry, Monoclonal antibodies, Hairy cell, CD103, CD11c
