Tretinoin for the treatment of cutaneous graft-versus-host disease.

Chronic graft-versus-host disease (GVHD) of the skin is a common complication of allogeneic bone marrow transplantation. It can be resistant to common methods of systemic immunosuppression. We report successful treatment of a patient with progressive cutaneous GVHD that was resistant to cyclosporine and steroids after allogeneic marrow transplantation for acute myelogenous leukemia using topical tretinoin (Retin-A).
