Carcinoma of a remnant cystic duct found on gastrointestinal fiberscopy

Abstract

The patient was a 69-year-old woman, who, in 2001, had a laparoscopic cholecystectomy due to the presence of choleliths. In 2008, a submucosal tumor was found on gastrointestinal fiberscopy ; the patient was asymptomatic. After further examinations, this tumor was thought to be either a primary or a matastatic duodenal cancer. The patient underwent surgery. On pathology, carcinoma of the remnant cystic duct was diagnosed. Carcinoma of a remnant cystic duct is extremely rare. In this paper, we review of cystic duct carcinoma cases and discuss the relevant literature.
