Nabothian cyst Health Article

Definition

A nabothian cyst is a mucus-filled lump on the surface of the cervix.

Causes, incidence, and risk factors

The cervix is lined with cells that release mucus. These cells can become covered by a type of skin cells called squamous epithelium. When this happens, the secretions build up in the plugged cells. They form a smooth, rounded bump on the cervix. The bump is called a nabothian cyst.

Each nabothian cyst appears as a small, white pimple. There can be more than one.

Symptoms

There are no symptoms.

Signs and tests

During a pelvic exam, the doctor will see a small, smooth, rounded lump (or collection of lumps) on the surface of the cervix. Rarely, a colposcopy is necessary to distinguish nabothian cysts from other bumps and sores that can occur on the cervix.

Treatment

No treatment is necessary. Nabothian cysts do not cause any problems.

They do not go away by themselves, but the cysts can be esaily removed at the doctor's office using electrocautery or cryotherapy. This is rarely necessary.

Expectations (prognosis)

Nabothian cysts do not cause any harm. They are a benign condition.

Complications

Rarely, cysts become so numerous or enlarged that the cervix becomes enlarged or blocked, making it difficult to take a Pap smear.

Calling your health care provider

This condition is usually discovered during a routine pelvic examination.

Prevention

There is no known prevention.
