Intraductal Mucosal Spreading Mucin Secreting Intrahepatic Cholangiocarcinoma / 한국간담췌외과학회지

ABSTRACT

Peripheral cholangiocarcinoma refers to an adenocarcinoma arising from the bile ducts peripheral to the secondary confluence. The growth pattern of the peripheral cholangiocarcinoma may be classified into the mass-forming type, the infiltrating type, the intraductal polypoid type and the combined type. Intraductal mucosal spreading, mucin secreting intrahepatic cholangiocarcinoma is a rare subtype of peripheral cholangiocarcinoma. Its existence has been neglected due to its paucity. A 59-year old male who presented with jaundice was admitted to our hospital because of recurrent cholangitis. A MRI of the abdomen showed the dilated intrahepatic duct without mass lesions. Left hepatectomy was done with negative surgical margins. The pathologic diagnosis was intraductal mucinous type cholangiocarcinoma without stromal invasion. Intrahepatic duct stone was found. The postoperative duodenal ulcerous bleeding was treated by suture ligation of the bleeding vessels of the duodenum. The patient discharged 65 days after the operation.
