Papillary carcinoma of the gallbladder and anomalous pancreatico-biliary junction. Report of three cases and review of the literature

Papillary carcinoma of the gallbladder is less invasive, less frequently metastasizes and results in a longer survival than other gallbladder tumors. It is frequently associated with Anomalous Pancreatico-biliary junction (APBJ), a malformation that occurs most frequently in Japan. Consequently, most cases of papillary cancer have been reported in the Japanese literature, while the incidence of this neoplasm, and its association with APBJ, is still unknown in Western Countries.
