Transfusion associated GVHD.

Transfusion-associated graft-versus-host disease (TA-GVHD) is an under-diagnosed condition in clinical practice. It can occur in immunocompromised as well as immunocompetent hosts and may follow allogeneic bone marrow transplant or transfusion from a related donor. The clinical course is stormy with a high mortality rate. Avoiding the use of blood transfusions from related donors and irradiation of blood products can prevent graft versus host disease. A case of graft versus host disease following related donor transfusion is presented here.
