A giant cervical nabothian cyst compressing the rectum, differential diagnosis and literature review.

Nabothian cysts generally being small-sized and multiple are common gynecopathological conditions of women in reproductive age. We report a case of a giant nabothian cyst compressing the rectum apparently without gynecologic symptoms. Initial symptoms of pain and difficulty in defecation due to compression on the rectal wall because of the huge size of the cyst might be the first case in the literature. We made the differential diagnosis from adenoma malignum (minimal-deviation adenocarsinoma) by using immunhistochemical and histopathological techniques.
