Bile Duct Carcinoma in Association with a Choledochal Cyst ― Report of a Case ―
A case of bile duct carcinoma associated with a pre-existing type I-A choledochal cyst is reported here. A 38-year-old man who had received a Roux-en-Y hepaticojejunostomy for a cyst of the common bile duct 11 years earlier was revealed to have metastatic carcinoma in the lungs. The primary site of the carcinoma was clinically undetermined, but was found by autopsy to be in the bile duct. Although the relation between these two lesions was unclear, circumstantial evidence suggested that they were related to each other. A persistent chronic inflammatory irritation in this area was considered to be responsible for development of the tumor.
