Cyst of Bartholin gland

**Definition:** A condition of the vagina, caused by growth of a flap of skin, occlusion of the Bartholin duct due to mucus, or infection. This condition is characterised by the accumulation of mucus or clear fluid in a closed sac-like structure that forms on (or from) one of the Bartholin glands or its ducts. This condition is commonly asymptomatic, but may become painful if the cyst becomes enlarged or infected.
