Cytomegalovirus-associated gastric ulcer.

A patients with a cytomegalovirus (CMV) post-transfusion syndrome developed upper gastrointestinal tract bleeding; subsequently, a gastric ulcer was found. CMV was searched for in the gastroscopic biopsy material because the gastric ulcer had occurred in a setting of CMV mononucleosis. CMV cells were found in gastroscopic biopsy sections and CMV was also cultured from biopsy material. This study illustrates the feasibility of antemortem diagnosis of CMV-associated disease of the upper gastrointestinal tract.
