A 55-year-old woman admitted for gallstones was found in ultrasonography and abdominal CT scan to have a cystic lesion 30mm in diameter in the body of the gallbladder, which divided the gallbladder into two parts, neck and fungus. Small gallstones were also seen at the neck of the gallbladder. We undertook laparoscopiccholecystectomy. Macroscopic examination found a large cyst in the body of the gallbladder and some gall-stones at the neck of the gallbladder. An incision showed to be filled with coagulated bile. Histologically, the cyst was an enlarged Rokitansky-Aschoff sinus whose inner surface was lined by a single layer of papillary hyperplasia and well differentiated adenocarcinoma. Gallbladder cysts are rare, with only 4 cases of cancerous gallbladder cyst reported worldwide in so far as we know. We report this extremely rare combination of gall-bladder cyst and cancer, together with a review of the literature.
