Causes, Incidence and Risk Factors Vaginal cysts may form as a result of trauma sustained by the vaginal walls which subsequently does not heal to normal smoothness. Gartner's duct cysts develop in the space occupied by the Gartner's duct. This duct is active in the fetus but disappears after birth. Benign tumors of the vagina are uncommon and are usually cystic.
Vaginal trauma is the only known risk factor.
There are usually no symptoms, however, there may be a lump felt in the vaginal wall or protruding from the vagina . A biopsy may be necessary to rule out vaginal cancer . Surgical excision may also be elected or possibly required. The outcome is generally good. Frequently cysts remain small and require no treatmen.
