The cervical canal is lined by glandular cells that normally secrete mucus. These endocervical glands can become covered by normal squamous epithelium in a normal process called metaplasia.
These nests of glandular cells (nabothian glands) on the cervix may become filled with secretions. As secretions accumulate, a smooth, rounded lump may form just under the surface of the cervix and become large enough to be seen or felt upon examination.
Each cyst appears as a small, white, pimple-like elevation. They can occur singly or in groups, and they are not a threat to health. The cysts are more common in women of reproductive age, especially those who have already had children.
