A man who previously had several episodes of upper gastrointestinal he
morrhage from erosive gastritis developed recurrent hemorrhage. Endosc
opy showed punctate hemorrhages in the fundus and body of the stomach,
plus a discrete area of thickened folds in the anterior wall. Biopsie
s revealed a dense mucosal infiltrate that included cytomegaloviral in
clusions. Bleeding continued despite treatment with blood transfusions
and ranitidine. Because of continued hemorrhage, and to distinguish t
he cause of the thickened folds, surgical biopsy was performed that sh
owed lymphoid germinal formations, characteristic of pseudolymphoma. H
e responded to i.v. ganciclovir and has had no further bleeding during
2 years of follow-up.
