A 69-year-old woman underwent a pancreaticoduodenectomy at the age of 41 years for a submucosal tumor of duodenum, which was diagnosed as leiomyoma at that time. Twenty eight years later, a liver tumor, which is 10 cm in a diameter, was identified on an abdominal ultrasonography. The left hepatectomy was undertaken. Immunohistochemical examination indicated that the tumor was positive for c-kit and diagnosed as a gastrointestinal stromal tumor(GIST). The pathological reexamination revealed the primary tumor was also positive for c-kit and diagnosed as GIST. Therefore, the liver tumor was considered as a metastasis of the duodenal GIST, which was resected 28 years earlier.
