This video shows a rare case where hepatocellular carcinoma (HCC) mainly progressing to the bile duct was observed by peroral cholangioscopy (POCS).

HCC, in which a primary tumor cannot be detected in the liver, is especially rare and is reported to be difficult to diagnose because of the low incidence, low recognition, and difficulty in diagnosis by conventional imaging alone. We were able to capture a POCS image of HCC with bile duct progression, which is incredibly rare.

We hope that this video will help to differentiate hepatocellular carcinoma from similar tumors observed in POCS, and we believe it will help gastroenterologists diagnose future cases.
