Familial adenomatous polyposis (FAP) may be associated with some extracolonic manifestations which in this vein, it is known as Gardner’s syndrome. To our knowledge, so far, there is no report of mucinous cystadenoma in association with FAP.We report a 31-year-old woman with FAP who underwent total proctocolectomy with ileal pouch-anal anastomosis 5 years earlier. During endoscopic surveillance, she was found to have a submucosal lesion in rectal cuff.Endoscopic ultrasound (EUS) revealed a round submucosal anechoic lesion measuring about 3 cm originating from the second layer of the rectal cuff. Surgical resection was performed and a cystic tumor was removed. Histologic examination was consistent with mucinous cystadenoma.FAP can be associated with mucinous cystadenoma.
