[Gastroesophageal infection caused by cytomegalovirus in immunodepressed patients. Presentation of 3 cases]. / Infección gastroesofágica por citomegalovirus en pacientes inmunodeprimidos. Presentación de tres casos.

We report three cases of upper gastrointestinal infection by Cytomegalovirus in immunocompromised patients. Two patients suffered from AIDS and the other one had a recent heart transplantation and was on immunodepressant drugs for an episode of rejection. The stomach in two cases and the esophagus in the other were the affected organs. In all cases there were upper gastrointestinal symptoms and the diagnosis was established by biopsy of endoscopically suspicious lesions. Antiviral therapy was effective in all three cases. This diagnosis has to be considered whenever immunocompromised patients present with unusual clinical and endoscopic findings.
