NABOTHIAN CYSTS


Nabothian cysts are mucus-filled cysts on the surface of the uterine cervix. The
cervical canal is lined by glandular cells that normally secrete mucus. These
endocervical glands can become covered by squamous epithelium through
metaplasia.


This is a benign condition. Rarely, cysts may become so numerous or enlarged
that the cervix becomes clinically enlarged.


Pelvic examination reveals a small, smooth, rounded lump (or collection of
lumps) on the surface of the cervix. Rarely, a colposcopic exam is necessary to
distinguish nabothian cysts from other types of cervical lesions.


Management. No treatment necessary; however, nabothian cysts do not clear
spontaneously. They can be easily cured through electrocautery or cryotherapy,
either of which can be done in the doctor’s office.


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. The cysts 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 women who have
already had children. There are no observable symptoms.
