Résumé
Cytomegalovirus (CMV) is a relatively common viral pathogen, and CMV infection is generally assumed asymptomatic in general hosts. In immunologically compromised patients, CMV infection can cause further serious diseases such as pneumonitis, retinitis, encephalitis, and enterocolitis. A 40-year-old man is being presented with acute fever, myalgia, and sore throat. Laboratory findings have revealed elevated ESR, CRP, and ferritin levels. The patient was being treated for adult-onset Still's disease (AOSD). Three weeks later, although AOSD activity was under control, the patient began to complain about oral soreness, epigastric pain, and diarrhea. Endoscopy revealed multiple round ulcers with white patches in the esophagus and the stomach, sparing the colon. Anti-fungal agent is being administered but failed to bring improvements after 2 weeks of therapy. CMV infection is confirmed with pathology, antiviral agents were initiated after the ulcers subsided. Currently, clinical associations between CMV infection and AOSD are suggested. CMV infection may be considered as a differential diagnosis when multiple upper gastrointestinal ulcerative lesions develop within patients whom have been treated AOSD with immunosuppressive agents.
