title: Relapsing post-transfusion purpura. A preventable disease.
abstract: Post-transfusion purpura is an isoimmune disorder that can recur if unrecognized. A 56-year-old woman is described who had her third episode of post-transfusion purpura 17 years after her last exposure to the inciting antigen. Clinical and immunologic features are reviewed, and specific preventive measures are proposed.
