Does the endoscopic finding of esophageal metastatic hepatocellular carcinoma progress from submucosal mass to polypoid shape?

Background Esophageal metastasis of hepatocellular carcinoma (HCC) is extremely rare; it was not serially followed-up by endoscopy. Objective Our purpose was to report the endoscopic findings according to the progression of esophageal metastatic HCC. Design Case report. Results In the review of the cases, submucosal tumor or polypoid mass were the most common endoscopic findings, and the locations of esophageal metastatic tumors are variable. The tumors had progressed from a submucosal mass to a polypoid mass in the current case. Limitation Small number of cases. Conclusions The endoscopic findings of esophageal metastasis of HCC may be changed from submucosal mass to polypoid mass.
