Abstract
A case of the double cancer developing in the common bile duct and in the gallbladder is presented. The patient was a female,67 years old. Her jaundice was pointed out by the family physician, and she was admitted to our hospital. The cancer of the common bile duct and the gallbladder was diagnosed by ERCP, US and CT, respectively. Both of these lesions were resected by pancreatico-duodenectomy. The reasons for diagnosis of the double cancer in this case were as follows: 1) There was no continuity between these lesions; 2) These cancers were developed from the mucosa to the deep layer; 3) There were dysplasia around these lesions. In the analysis of the DNA pattern, the aneuploid pattern was demonstrated from the cancer of the gallbladder by the flow cytometry, while the diploid pattern was demonstrated from the No 12 b2lymphnode, which was metastasis of the cancer of the common bile duct.
