Report of a Resected Case of Cholangiocellular Carcinoma Originating in the Caudate Lobe

A case of cholangiocellular carcinoma originating in the caudate lobe is presented. The patient, a 69-year-old woman, was operated on initially for cholelithiasis and a T-tube was inserted into the choledochus. After the operation cholangiography through the T-tube revealed shadow defects in the right hepatic duct. After cholangioscopy, biopsies and computed tomography, we made a diagnosis of papillary carcinoma of the right caudete lobe. At the second operation the right caudete lobe was found to be occupied by the tumor but the liver capsule was still intact. Curative surgery, which included right hepatic lobectomy with total caudate lobectomy and resection of the extra hepatic bile duct, was performed. The histopathological finding was papillary adenocarcinoma which had colloidal proliferation into the distal parenchyma of the right caudete lobe. The patient has now been enjoying a normal social life for 3.5 years with no signs of recurrence.
