title: [A case report of primary double cancer of the stomach and choledochus].
abstract: We encountered a relatively rare case of primary double cancer arising simultaneously from both the stomach and choledochus in a 72-year-old woman with obstructive jaundice. The patient was admitted to Saiseikai Shigaken Hospital, and was diagnosed as having both early gastric cancer at the lesser curvature of the antrum and cancer of the choledochus. She underwent curative pancreato-duodenectomy with extended gastrectomy. One of the resected tumors was histopathologically diagnosed as a well differentiated, tubular adenocarcinoma of the stomach with invasion reaching as deep as the submucosa. The other tumor was a moderately differentiated, tubular adenocarcinoma of the choledochus with lymph node metastases (hepatic, retroligamentic, paracholedochal, and posterior and superior pancreaticoduodenal lymph nodes). Our review of the literature suggests that the incidence of primary double malignancies is on the increase.
