A Case of Adenomyoma Causing Jejunal Bleeding / 대한소화기내시경학회지

ABSTRACT

Adenomyoma, a benign tumor generally considered to be a form of pancreatic heterotopia, is composed of smooth muscle and undifferentiated columnar epithelium. A 62-year-old female was admitted with melena. Small bowel enteroscopy using a pediatric colonoscope revealed a small sized nodular mass with active bleeding in the proximal jejunum. After a endoscopic resection of the tumor, the bleeding ceased. Histologic examination disclosed an adenomyoma. We report a case of the adenom-yoma causing jejunal bleeding with a review of the literature.
