Mucinous intrahepatic cholangiocarcinoma: a distinct variant

Mucinous variant of intrahepatic cholangiocarcinoma (iCC) is rare, and its clinicopathological features and prognosis are far less clear. Six patients who had iCCs with more than 50% of mucinous component and 79 conventional iCCs were included in the study. The mean size of mucinous and conventional iCCs was 6.2cm and 6.0cm, respectively. The majority of patients (83%) with mucinous iCC presented at T3 stage or above, compared to 28% of the conventional group (p<0.01). Three patients with mucinous iCC (50%) died within 1year.
