Graft-versus-host disease. Case report and discussion.

The graft-versus-host disease reaction is an immunologic consequence resulting from the grafting of immunocompetent cells from one individual to an immunocompromised host. The oral manifestations of this disease process include severe oral pain, xerostemia, ulcerative lesions, and mucositis. With appropriate history and diagnostic testing, these lesions can be differentiated from other oral diseases having similar clinical appearance.
