This paper by Abi-Rached and Neugut provides an overview of the diagnosis and treatment of gallbladder carcinoma, a rare, yet frustratingly difficult disease to manage [1]. Overall, we agree with the risk factors described in this review. We would add that, in addition to chronic cholecystitis, porcelain gallbladder, and retained gallbladder (secondary to cholecystostomy), cholecysto-enteric fistulas have also been associated with a higher incidence of gallbladder carcinoma [2,3] Patients with ulcerative colitis are known to be at higher risk for cholangiocarcinoma, and there is also some evidence that these patients have an increased risk of gallbladder cancer.
