Large Nabothian Cyst Obstructing Labour Passage.

Nabothian cysts are common and silent retention cysts of the uterine cervix with no particular intervention required. It is quite rare to reach a size of more than 4 cm and it is a diagnostic dilemma to differ it from adenoma malignum. We report a case of a woman with 38 weeks of gestation presented to the maternity unit with labour pain and protruding cystic mass (60x70 mm) out of the vagina. Simple drainage was performed to allow the vaginal delivery. She delivered 4130 grams, 9-10 Apgar, male baby by spontaneous vaginal delivery. The patient's and the newborn postpartum course was uneventful. Gynaecologic examination revealed a persisting cystic mass in the cervix (40x50 mm) two months after the delivery. We performed a total excision of the cyst to confirm the pathologic diagnosis. This paper is the first report of nabothian cysts obstructing labour passage. In the view of this case, we aimed to discuss cervical cystic masses and a review of the literature.
