Which of the following is a cystic remnant of Wolffian duct?

Ganer's cyst: These uncommon vaginal cysts develop from remnants of the mesonephric (Wolffian) ducts. They are typically asymptomatic and are usually found within the lateral vaginal wall during routine examination. Symptoms however may include dyspareunia, vaginal pain, and difficulty inseing tampons or other vaginal devices. Examination reveals a tense cyst that is palpable or seen to bulge beneath the lateral vaginal wall. Observation is reasonable in most cases, although marsupialization or excision may be appropriate for symptomatic Ganer duct cysts.Also know:A Baholin's cyst is formed when a Baholin's gland is blocked, causing a fluid-filled cyst to develop. A Baholin's cyst is not an infection, although it can be caused by an infection, inflammation, or physical blockage (mucus or other impediment) to the Baholin's ducts (tubes which lead from the glands to the vulva).Ref: Hoffman B.L., Schorge J.O., Schaffer J.I., Halvorson L.M., Bradshaw K.D., Cunningham F.G., Calver L.E.
