Several types of vaginal cysts exist, and they can range in size from the size of a pea to that of an orange. Vaginal inclusion cysts are the most common type of cyst found in the vagina. They may form as a result of trauma sustained by the vaginal walls or after obstetric or gynecologic vaginal procedures, when the vaginal lining doesn't heal to normal smoothness.
Gartner's duct cysts develop in the space occupied by the Gartner's duct, usually on the lateral walls of the vagina. This duct is active in the fetus but usually disappears after birth, and portions of the duct may collect fluid and present as a vaginal wall cyst later in life.
Benign tumors of the vagina are uncommon and are usually cystic.
