Gartner’s duct cyst (GDC) is a remnant of the mesonephric (Wolffian) duct in females. The GDC is formed from the persistence of some portions of the mesonephric duct in adult females resulting in small-sized cysts usually in the anterolateral vaginal wall but could be found elsewhere along the tract of the duct. The case of a 33-year-old para 5+1 (three alive) woman who had GDC is reported. The patient presented with incidental findings of a vaginal mass during gynecological evaluation and subsequently had dyspareunia. A provisional diagnosis of GDC was made and this was confirmed by transvaginal ultrasound. The patient had transvaginal excision of the cyst and histological confirmation of a benign cystic lesion with the diagnosis of GDC. GDC is a rare entity and clinical examination revealing a cystic vaginal wall mass with or without symptoms should raise a high suspicion of this condition.
