The patient presented with two episodes of massive melena. Endoscopic examination showed a rare, ulcerative tumor of the duodenum proximal to the duodenal papilla with biopsy finding of leiomyoma. He was referred to the University hospital in May, 1997. Diagnostic modalities (Upper GI series, CT, angiography and MRI) confirmed the tumor. At laparotomy the tumor was tightly adhered to the pancreatic head, which makes it impossible to be removed locally. Subsequently, pancreatoduodenectomy was done with reconstruction using Child's procedure. The tumor was ulcerative, relatively well-defined, and 5.5×5cm in size, protruding over the mucosal surface and into the subserosa. The tumor was diagnosed to be a low-grade leiomyosarcoma by histological and immunohistochemical study. He was uneventfull postoperatively and has been enjoying his normal life., 論文}, pages = {45--48}, title = {[症例報告]膵頭十二指腸切除術(PD)を要した十二指腸 stromal tumorの1例}, volume = {18}, year = {1998} }
