title: [Cytology and immunophenotype features of hairy cell leukemia: 6 cases].
abstract: BACKGROUND
  Hairy cell leukemia is a rare lymphoproliferative disorder.
  
  
  OBJECTIVE
  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.
  
  
  CONCLUSIONS
  Immunophenotype is of great interest in the diagnosis of hairy cell leukemia.
