Opportunistic gastritis in graft-versus-host disease.

Two patients underwent bone marrow transplantation and subsequently developed graft-versus-host disease. Barium examination showed a gross nodular pattern in the stomach in one patient, an appearance not previously described. Both patients developed characteristic changes in the small bowel and in one the colon was also affected. The dramatic rise in the patient's cytomegaloviral titers (CMV) and the presence of viral inclusion bodies in gastric cells suggest that the changes in the stomach may be due to a CMV gastritis.
