Cervical retention cysts are not serious. Also known as cervical glandular cysts, cervical glandular cysts are in the vast majority of cases physiological changes of the uterine cervix. In the process of replacing the columnar epithelium with squamous epithelium in the transformation zone of the cervix, the new squamous epithelium covers the mouth of the cervical glandular ducts or penetrates deep into the glandular ducts, blocking the mouth of the glandular ducts, resulting in obstruction of the drainage of glandular secretions and retention of the cysts. Local injury to the cervix or chronic inflammation of the cervix, which narrows the mouth of the glandular ducts, can also lead to the formation of cysts of the cervical glands. Myometrial glandular cysts usually do not require treatment. Superficial cervical glandular cysts are easily diagnosed on examination and are seen as single or multiple small greenish-white vesicles protruding from the surface of the uterine cervix. Deep cervical glandular cysts with no abnormality on the surface of the cervix, showing cervical hypertrophy, should be differentiated from cervical cancer. Therefore, for retention cysts of the cervix, cervical cancer screening is recommended, and if the cervical cancer screening is normal, there is no need to deal with cervical retention cysts.
