Abstract
A case of early carcinoma of the cystic duct protruding into the bile duct was reported.
A 81-year old man presented with common fever. A malignancy of the bile duct was strongly suspected by ultrasonography, endscopic retrograde cholangiography and percutaneous transhepatic cholangiography.
A papillomatous tumor of the cystic duct prolapsed into the bile duct was found in the resected specimen. Microscopically, the tumor was identified as papillary adenocarcinoma and limited in the mucosa of the cystic duct. There were no metastasis in the lymphnode.
Primary carcinoma of the cystic duct is a rare disease. To our knowledge, only 30 cases were reported in the world literature, but cystic duct carcinoma protruding into the common bile duct was not found in them. And this is the first case of the cystic duct carcinoma that limited in the mucosa in Japan.
