A cyst is a closed sac, having a distinct membrane and division on the nearby tissue. It may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst could go away on its own or may have to be removed through surgery.

[edit] Cystic fibrosis

Despite being described in 1938 as the microscopic appearance of cysts in the pancreas,[5] cystic fibrosis is an example of a genetic disorder whose name is related to fibrosis of the cystic duct and does not involve actual cysts.[6]

[edit] Cystic neoplasm

Most cysts in the body are benign (dysfunctional) tumors, the result of plugged ducts or other natural body outlets for secretions. However sometimes these masses are considered neoplasm:

[edit] Treatment

Treatment ranges from simple enucleation of the cyst to curettage to resection. There are cysts, e.g. buccal bifurcation cyst with self-resolation nature, in which close observation only can be employed unless the cyst is infected and symptomatic.[2]

[edit] Related structures

A pseudocyst is collection without a distinct membrane.

A syrinx in the spinal cord or brainstem is sometimes inaccurately referred to as a cyst.
