Ciliated hepatic foregut cyst (CHFC) is a rare, benign, solitary cyst consisting of ciliated columnar epithelium. They are lined by a layer of ciliated columnar cells and contain mucoid material and debris. It is the ciliated epithelium that distinguishes them from other hepatic cysts. The cyst is generally found incidentally on radiologic imaging or during surgical exploration. There has been an increase in the number of reports of CHFC during the past 15 years in the surgical pathology literature, presumably because of increased availability of various radiologic imaging modalities. Although it is rare, CHFC should be included in the differential diagnosis of cystic lesions of the liver and is important to consider in aspirates obtained for the evaluation of possible neoplastic disease. We report a case diagnosed by fine-needle aspiration for a liver cyst discovered incidentally during the evaluation of acute pancreatitis.
