Postgastrectomy protein-losing cytomegalovirus jejunitis in an immunocompromised patient

A 59-year-old man was admitted because of nausea and fatigue. He had been diagnosed with gastric adenocarcinoma 7 months earlier, and because of gastric outlet obstruction had undergone total gastrectomy with esophagojejunostomy and omentectomy (pT3N3bM0R1). Postoperatively, platinum-based chemotherapy was initiated, followed by radiochemotherapy (5-fluorouracil + 45 Gy) approximately 2 weeks before admission.
