Synchronous malignancies of the gall bladder and common bile duct: a case report

[Synchronous primary multiple cancer: distal cholangiocarcinoma of the intrapancreatic common bile duct and intraductal papillary mucinous tumor associated with ductal adenocarcinoma of the pancreatic tail]

We present a combination of distal cholangiocarcinoma of the intrapancreatic common bile duct and intraductal papillary mucinous tumor associated with ductal adenocarcinoma of the pancreatic tail. This clinical case is unique. When analyzing the literature, we found no any case of similar primary multiple malignant tumor. Importantly, final diagnosis of simultaneous malignant pancreatobiliary neoplasia is possible only via intraoperative biopsy after adequate morphological dissection and research of resected organ complex including molecular genetic analysis due to identical histological and immunohistochemical picture of ductal neoplasia.

Synchronous primary duodenal papillary adenocarcinoma and gallbladder carcinoma: A case report and review of literature

BACKGROUND

Synchronous primary cancers (SPCs) have become increasingly frequent over the past decade. However, the coexistence of duodenal papillary and gallbladder cancers is rare, and such cases have not been previously reported in the English literature. Here, we describe an SPC case with duodenal papilla and gallbladder cancers and its diagnosis and successful management.

CASE SUMMARY

A 68-year-old Chinese man was admitted to our hospital with the chief complaint of dyspepsia for the past month. Contrast-enhanced computed tomography of the abdomen performed at the local hospital revealed dilatation of the bile and pancreatic ducts and a space-occupying lesion in the duodenal papilla. Endoscopy revealed a tumor protruding from the duodenal papilla. Pathological findings for the biopsied tissue revealed tubular villous growth with moderate heterogeneous hyperplasia. Surgical treatment was selected. Macroscopic examination of this surgical specimen revealed a 2-cm papillary tumor and another tumor protruding by 0.5 cm in the gallbladder neck duct. Intraoperative rapid pathology identified adenocarcinoma in the gallbladder neck duct and tubular villous adenoma with high-grade intraepithelial neoplasia and local canceration in the duodenal papilla. After an uneventful postoperative recovery, the patient was discharged without complications.

CONCLUSION

It is essential for clinicians and pathologists to maintain a high degree of suspicion while evaluating such synchronous cancers.

Synchronous gallbladder squamous cell carcinoma and adenocarcinoma, both as primary tumors in one patient

INTRODUCTION

Synchronous primary carcinomas of gallbladder are extremely rare. In this paper, we report a case of double primary carcinomas in gallbladder CASE REPORT: A 65 year old male was admitted to the hospital for surgical removal of gallbladder, which was diagnosed as cholecystitis in ultrasonography. Macroscopic examination disclosed a single whitish mass in gallbladder neck and another distinct mass in the fundus as wall thickening. Pathologic findings revealed squamous cell carcinoma of the neck and adenocarcinoma in the fundus.

DISCUSSION

This study represents an example of misdiagnosis. Being cautious is mandatory in order to manage the patient properly.

CONCLUSION

Synchronous primary carcinomas of gallbladder are rare. However this diagnosis should be taken into account in patients with cholecystitis features in order to seeking for the best surgical approach.
