Which among the following structure give rise to Ganer's cyst?: (A) Remnant of paramesonephric duct, (B) Remnant of mesonephric duct, (C) Cervix, (D) Vagina
Answer is B. Ganer's duct cyst arises from incomplete regression of the vaginal poion of the Wolffian (mesonephric) ducts. Ganer's ducts are determined by the presence of persistent remnants of mesonephric ducts. Since the mesonephric ducts have secretory propeies, cysts can develop. Usually, cysts located along the anterior-lateral vaginal wall, matching the Wolffian duct path, are <=2 cm in size and asymptomatic.
