Esophageal cast: a manifestation of graft-versus-host disease.

Diffuse involvement of the gastrointestinal tract by graft-versus-host disease (GVHD) is a common complication of bone marrow transplantation. The esophageal involvement in this disease tends to be a vesiculobullous, ulcerative or desquamative process. To our knowledge, esophageal cast has not been described in the context of GVHD. However, it has been described as a result of trauma to the esophagus or in association with bullous disease of the skin. We present a case of esophageal cast in a patient with chronic GVHD following bone marrow transplant.
