A cyst is a closed sac having a distinct membrane and division on the nearby tissue. It may contain air, fluid, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, the cyst will remain in the tissue but can be removed by surgery or resolve by taking medications. A cyst may also be a sack that encloses an organism during a dormant period, such as in the case of certain parasites. This type of cyst may, for instance, protect a parasite from the churning acid of the stomach so it may pass through to the intestines unharmed where it can then break out. Cystic fibrosis is an example of a genetic disorder whereby cysts and fibrosis develop in the lungs.
Locations
- Arachnoid cyst (between the surface of the brain and the cranial base or on the arachnoid membrane)
- Chalazion cyst (eyelid)
- Cysticercal cyst (the larval stage of Taenia sp.)
- Dentigerous Cyst (associated with the crowns of non-erupted teeth)
- Epididymal Cyst (found in the vessels attached to the testes)
- Ganglion cyst (hand/foot joints and tendons)
- Glial Cyst (in the brain)
- Gartner's duct cyst (vaginal or vulvar cyst of embryological origin)
- Keratocyst (in the jaws, these can appear solitary or associated with the Gorlin-Goltz or Nevoid basal cell carcinoma syndrome. The latest World Health Organization classification considers Keratocysts as tumors rather than cysts)
- Meibomian cyst (eyelid)
- Nabothian cyst (cervix)
- Ovarian cyst (ovaries, functional and pathological)
- Paratubal cyst (fallopian tube)
- Pilonidal cyst (skin infection near tailbone)
- Renal cyst (kidneys)
- Radicular cyst (associated with the roots of non-vital teeth)
- Sebaceous cyst (sac below skin)
- Tarlov cyst (spine)
- Vocal fold cyst
- Dermoid cyst (Skull and ovaries)
- Breast cyst
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.
