title: Acute lymphoidic leukemia in a patient with thrombocytopenia/absent radii (Tar) syndrome.
abstract: OBJECTIVE
  Patients with thrombocytopenia, absent radii (TAR) syndrome have a spontaneous amelioration of thrombocytopenia after infancy. No individual with the syndrome has been reported to develop subsequent bone marrow disease.
  
  
  METHODS
  We report a child with TAR syndrome who developed acute lymphoidic leukemia.
  
  
  CONCLUSIONS
  The TAR syndrome may predispose patients to other forms of marrow disease (as do other inherited marrow failure diseases). Additional cases are needed to confirm this hypothesis.
