[Late cervical pregnancy (author's transl)].

A cervical pregnancy which develops into the last trimester of gestation with a viable infant is a very dangerous and rare condition. A personal observation of such a case at 31 weeks gestation is added to the 8 cases known in the literature. Extreme dilatation of the cervical wall with extensive vascularization is typical for this condition associated with placenta increta or accreta. The uterine body tops the cervical pregnancy like a cap. Cesarean section followed by hysterectomy is the management of choice.
