Graft-versus-host disease of the skin and adjacent mucous membranes.

Graft-versus-host disease is a complex multiorgan disease which mainly occurs in patients after allogeneic hematopoietic stem cell transplantation. The skin is the most frequently affected organ. Care and therapy of patients requires an interdisciplinary approach with dermatology in a key position.
