Background: The solid and papillary epithelial neoplasm of the pancreas (SPENP) is a low grade malignancy and has a predilection for young woman patients. Local recurrence or distant metastasis has been very rarely reported. Death caused by the tumor metastases has rarely occurred. Here, we report a patient with recurrent SPENP, who developed cytomegalovirus (CMV)-related gastric ulcer mimicking carcinoma after chemotherapy and radiotherapy.Case Report: A 45-year-old woman with a 2 years' history of SPENP developed multiple liver metastases one year after surgery and underwent palliative chemotherapy and radiotherapy. She was admitted because of intermittent fever and melena episodes for several days. An upper GI endoscopy revealed multiple ulcerative lesions in the antrum of the stomach which were thought to be metastatic carcinoma. The pathological report, however, revealed CMV inclusion bodies in the gastric mucosa and there was no evidence of malignancy. Blood CMV PCR assay also showed CMV-positive results. The symptoms of fever and melena improved after two weeks of ganciclovir treatment.Conclusions: CMV disease should be considered in cancer patients with unusual GI symptoms. Early intervention with antiviral therapy can improve outcome and reduces severe complications.
