What is it?

Benign neoplasms of the vagina are quite rare and include cysts and lesions that are not cancerous. Some of the benign neoplasms include:
Vaginal inclusion cyst/Epidermal inclusion cyst- the most common benign neoplasm. It is usually small and located on the posterior, lower end of the vagina.
Gartner’s duct cyst and paramesonephric cysts - these ducts are supposed to disappear before birth, but if it is not fully absorbed it could cause a cyst.
Bartholin gland cyst- The Bartholin glands are located on the sides of the vaginal lips, secreting lubricants. If the opening of these glands is blocked, painless swelling may develop.
There are also two kinds of solid benign tumors in the vagina- leiomyoma which appears on the front of the vaginal wall and fibroepithelial polyps which are small may grow in clusters and do not cause any symptoms.
Condyloma acuminatum is the name of the lesions caused by an HPV infection.
