サイトメガロウイルス感染症による十二指腸潰瘍の1例

Abstract

A 56-year-old man who had received bone marrow transplantation under the diagnosis of Hodgkin's lymphoma (Stage ⅣB) complained of tarry stool during of immunosuppresslve agent theropy. Upper gastrointestinal endoscopy revealed longitudinal ulcers in the second portion of the duodenum. Histological examination of the ulcer margin showed intranuclear inclusion bodies. Although we treated the patient with anti- CMV agent and proton pump inhibitor, he complained of tarry stool again. Upper gastrointestinal endoscopy revealed Dieulafoy's lesion in the superior duodenal angulus. However, it was difficult to observe this lesion by the rigid endoscope; we were able to observe and treat the condition by using endoscopic clipping with a transparent hood.
