Pseudotumoral appearance of cytomegalovirus esophagitis and gastritis in AIDS patients.

Cytomegalovirus (CMV) is frequently isolated from patients with acquired immunodeficiency syndrome (AIDS), and often causes disseminated disease. Gastrointestinal CMV involvement is recognized with increased frequency in AIDS patients. It can involve the entire alimentary tract and usually produces mucosal ulceration. Pseudotumoral lesions develop very infrequently. We report two unusual detailed cases of biopsy-proven CMV esophagitis and gastritis resembling carcinoma, in patients with human immunodeficiency virus infection. In AIDS patients, the gastrointestinal CMV involvement could show pseudotumoral appearance.
