A 59-year-old man with anorexia who had a history of cholecystectomy was referred to our hospital. Imaging examinations revealed a contrast-enhanced tumor in the residual cystic duct and a part of the common bile duct. Endoscopic retrograde cholangiopancreatography and peroral-cholangioscopy showed a papillary tumor with movement and a change in the shape. Under a diagnosis of primary cystic duct cancer, subtotal stomach-preserving pancreaticoduodenectomy was performed. The microscopic examination of a resected specimen revealed intracholecystic papillary-tubular neoplasm located in the residual cystic duct, forming a polypoid protrusion to the common bile duct and extensive intraepithelial progress in the common bile duct.
