[Porcelain gallbladder and cancer (author's transl)].

The porcelain gallbladder is a rare entity. It reaches especially the old woman. Most of the porcelain gallbladders have a great clinical latence. A cancer of the gallbladder exists in eleven per cent of the cases: this justifies a systematic cholecystectomy of the calcified gallbladders, even if they are asymptomatic. Another digestive cancer exists in nine per cent of the cases. Three personal observations of porcelain gallbladder which are associated with a cancer are described: they confirm the facts of the literature.
