In Pathology, “cyst” is the term used for lesions that consists of an epithelium-lined cavity that is filled by material that is generally fluid, mucinous or semi-solid.
Cysts can arise anywhere in the body and their epithelial lining varies according to the site and tissue they originate from.
Although cysts can have a bulky tumor-like appearance, the majority are completely benign non-neoplastic lesions. It should, however, be borne in mind that benign and malignant epithelial tumors arising at certain sites, like ovaries and pancreas, frequently present as cystic masses.
