Carcinoma of the head of the pancreas after excision of a choledochal cyst

We here report a 53-year-old woman who had undergone resection of a choledo chal cyst and hepaticojejunostomy three years before. She was readmitted be cause of intermittent fever, and abdominal computed tomography revealed a 4 -cm tumor in the head of the pancreas. We performed pancreatoduodenectomy, and examination of the resected specimen showed well-differentiated papilla ry adenocarcinoma. Only 5 cases of carcinoma occurring after the resection of a choledochal cyst have been reported, and to our knowledge, this is the second case of carcinoma of the head of the pancreas.
