title: Discrete gastrointestinal mass lesions caused by cytomegalovirus in patients with AIDS: report of three cases and review.
abstract: We report the detailed clinical features of discrete mass lesions of the gastrointestinal tract caused by cytomegalovirus in three patients who had the acquired immunodeficiency virus syndrome. The disease occurred in the fundus of the stomach in one patient and in the cecum in the other two persons. The symptoms as well as radiographic and endoscopic findings in each case are described and are shown to be indistinguishable from those resulting from a neoplasm. The diagnosis was established by the presence of inflammation with cytomegalovirus-like inclusions and confirmed by immunoperoxidase staining. Cytomegalovirus infection should be considered, along with Kaposi's sarcoma and lymphoma, as a cause of focal mass lesions of the alimentary tract in persons infected with HIV.
