[A case of obstructive jaundice and duodenal stenosis caused by vaginal cancer and retroperitoneal metastasis].

A 76-year-old woman with a history of radiation therapy for vaginal cancer was referred to our hospital because of fever and hepatobiliary dysfunction. Computed tomography showed stenosis of the lower bile duct and edema-like changes in the duodenum from the descending to transverse parts. Endoscopic biliary stenting was performed according to the rendezvous method. Squamous cell carcinoma, similar to vaginal cancer, was found on pathological examination of the duodenum. We accordingly diagnosed obstructive jaundice and duodenal stenosis caused by vaginal cancer and retroperitoneal metastasis. To the best of our knowledge, other such cases have not been reported.
