Ciliated Foregut Cyst of the Gallbladder: Report of a Case and Review of Literature

Cystic lesions of the gallbladder are very rare and they are generally lined by single columnar or mucinous epithelium. A ciliated cyst of foregut origin is extremely rare in gallbladder. To our knowledge, only five cases have been reported so far. Here, we present the sixth case found incidentally in ultrasonographic examination in a 41-year-old woman suffering from chronic right upper quadrant pain. Laparoscopic cholecystectomy was performed for the gallstones and a benign appearing cyst in ultrasonography. Macroscopically, a submucosal unilocular cyst was located in the neck of the gallbladder. There was no communication with the lumen. Histologically, the cyst was lined by pseudostratified ciliated epithelium containing goblet cells and had a muscular wall. The postoperative course was uneventful. Patient was discharged on the second day of the operation and was well after 2 months.
