Extensive vitiligo after ganciclovir treatment of GvHD in a patient who had received donor T cells expressing herpes simplex virus thymidine kinase Original Research Article

The use of donor T cells expressing a suicide gene for destruction of graft-versus-host effector cells provides a tool for alloreactivity modulation. We describe a case of extensive vitiligo that developed after ganciclovir treatment of cutaneous chronic graft-versus-host disease in a patient who had received donor T lymphocytes expressing herpes simplex virus thymidine kinase at the time of transplantation.
