title: Hemophagocytic lymphohistiocytosis complicating a T-cell rich B-cell lymphoma.
abstract: BACKGROUND
  Hemophagocytic lymphohistiocytosis in adults is often secundary to an infection or a neoplasm. In this last case, T cell lymphomas are the most frequent causes. Hemophagocytic lymphohistiocytosis secundary to a B cell lymphoma has been rarely reported.
  
  
  METHODS
  We describe a case of a hemophagocytic lymphohistiocytosis complicating a T-cell rich B-cell lymphoma treated with conventionnal chemotherapy leading to a complete remission.
  
  
  CONCLUSIONS
  Prompt etiologic diagnosis and treatment of hemophagocytic lymphohistiocytosis leads to satisfactory outcome.
