Abstract

Extrahepatic cholangiocarcinoma or extrahepatic bile duct carcinoma is an exceptionally discerned, malignant neoplasm. Majorities (~95%) of neoplasms appear as adenocarcinoma and tumefaction is infrequently encountered, in contrast to adenocarcinoma gallbladder. Extrahepatic cholangiocarcinoma exhibits localized tumour extension into ampulla of Vater, colon, duodenum, gallbladder, hepatic parenchyma, omentum, pancreas or gastric region. Tumours emerging from right hepatic duct or left hepatic duct may extend proximally into hepatic parenchyma or distally into common hepatic duct. Tumours arising from cystic duct extend into gallbladder or common bile duct. Tumours engendered from distal common bile duct extend to pancreas, duodenum, colon, omentum or gastric region. Tumour metastases into regional lymph nodes or sites as hepatic parenchyma, pulmonary parenchyma or peritoneum may ensue
