A Gartner's duct cyst (sometimes incorrectly referred to as vaginal inclusion cyst) is a benign vaginal cyst that originates from the Gartner's duct, which is a vestigial remnant of the mesonephric duct (wolffian duct) in females. They are typically small asymptomatic cysts that occur along the lateral walls of the vagina, following the course of the duct. [Source: Wikipedia
