Acute gastric mucosal lesions associated with cytomegalovirus infection in a non-immunocompromised host.

A 75-year-old woman with epigastric pain and tarry stool was admitted to our hospital, where upper gastrointestinal endoscopic study revealed multiple gastric ulcers. The endoscopic biopsy specimens obtained on the seventh hospital day disclosed a few typical intranuclear cytomegalovirus inclusions. Cytomegalovirus-DNA was detected using polymerase chain reaction in a biopsy specimen. No immunologic abnormalities were demonstrated by any laboratory tests. While only a few cases of cytomegalovirus-associated gastric ulcer in non-immunocompromised hosts have been reported, this entity may be more frequently detected when careful histological examination is performed in the active stage rather than postponed until after healing of the ulcer.
