Gastrointestinal cytomegalovirus (CMV) disease most frequently occurs in adults with immune deficiency due to acquired immune deficiency syndrome (AIDS), organ trans- plantation, cancer chemotherapy, and steroid therapy. Because the number of patients with immune deficiency has increased in recent years in Korea and CMV is one of the most common infecting complications in these settings, the number of patients with CMV disease is also increasing. Most cases of CMV disease are due to reactivation of a latent virus. The pathogenesis of this intestinal disease is vascular endothelial involvement with subsequent ischemic mucosal injury. An endoscopy usually reveals large, well defined ulcers greater than 3 cm. Deep longitudinal serpiginous ulcers represent a coalescence of adjoining smaller ulcers. CMV infection produces a characteristic cytomegalic cell containing a intranuclear inclusion, which is sometimes surrounded by a clear halo ("owl's eye"). The presence of cytomegalic cells on mucosal biopsy specimens stained with hematoxylin and eosin has been considered the golden standard for establishing the diagnosis of CMV gastrointestinal disease. Immunohistochemistry with monoclonal antibody to CMV antigens and in situ hybridization for CMV DNA are useful in the diagnosis. We report 2 cases of CMV esophagitis and proctitis which showed characteristic endoscopic and histologic findings of the CMV infection. (Korean J Gastrointest Endosc 18: 763-768, 1998)
