Abstract

Ciliated hepatic foregut cyst (CHFC) is very rare and apparently originated from embryologic foregut. It is generally benign, solitary cyst and microscopically consists of inner ciliated pseudostratified columnar epithelium, subepithelial connective tissue, a smooth muscle layer, and outer fibrous capsule. Although ciliated cysts commonly arise from the tracheal bronchial tree and the esophagus, they could also be found in the liver with rare incidence. There are several reports indicating this lesion can cause clinical problems, such as biliary obstruction and malignant transformation. Herein, we present a case of 56-year-old male patient who recently underwent laparoscopic excision of CHFC, focusing our discussion on review of literatures and rationale of laparoscopic surgery on CHFC.
