Ampullary carcinoma in familial adenomatous polyposis: report of a case

Gall bladder carcinoma with ampullary carcinoma: a rare case of double malignancy

Simultaneous double cancers in the biliary system are rare. Most are associated with pancreaticobiliary maljunction (PBM). However, it can occur in patients without PBM. Differentiation between these events is important since these two mechanistic origins imply different stages of disease, as well as different subsequent treatments and prognoses. Herein, we report a case of ampullary carcinoma associated with gall bladder carcinoma diagnosed nonoperatively and palliated with biliary metal stenting.
