From 1972 to 1985, 40 cases of congenital dilatation of the bile duct (CDBD) were experienced in the department of the authors. Those consisted of 19 cases of anomalous arrangement of the pancreaticobile duct (P‐B anomaly), five of bile duct carcinoma, and two of gall bladder carcinoma. In addition, four patients who showed no dilatation of the bile duct in spite of the presence of a P‐B anomaly were experienced, and coexistent gall bladder carcinoma was present in three of four cases. The incidence of bile duct carcinoma associated with CDBD is very high. However, coexistent gall bladder carcinoma in CDBD is a new topic, and coexistent intrahepatic bile duct carcinoma in CDBD is extremely rare. This report presents interesting and rare cases of coexistent carcinomas in these anomalies and investigates their carcinogenesis, particularly that of gall bladder carcinoma.
