title: Accessory cervix: an unusual congenital malformation.
abstract: A woman with a septate vagina and two cervices was observed. One of the cervices ended blindly. The other cervix communicated with a normal corpus and two normally positioned patent fallopian tubes. Two explanations for the origin of this accessory cervix are offered: (1) that it originated from a fusion failure of the lower portions of the müllerian ducts, and (2) that it arose from the urogenital sinus.
