Ciliated Foregut Cyst of Gallbladder: A Little Known Entity

Abstract

Ciliated foregut cysts are rare masses that develop from the tissues which remain from embryological foregut development. In the literature, a few cases have been described in various organs so far. The solitary cysts are characterized by ciliated pseudostratified columnar epithelium. They are usually located above the diaphragm but they can also arise in relation to the liver, gallbladder and pancreas. Although rare, there is a risk of development of squamous cell carcinoma from these cysts that typically bear benign features. Prognosis following the development of carcinoma is poor. Congenital gallbladder cysts are detected rather rarely. The diagnosis is suspected on imaging. Treatment using a laparoscopic surgical method is the first preference.
