Nabothian cyst

Definition

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

The cervix is part of the female body. It is at the lower end of the womb (uterus) at the top of the vagina. It is about 1 inch long.

Causes, incidence, and risk factors

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

Symptoms

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

Signs and tests

During a pelvic exam, the health care provider will see a small, smooth, rounded lump (or collection of lumps) on the surface of the cervix. Rarely, magnifying the area (colposcopy) may be needed to tell these cysts from other bumps that can occur.

Sometimes the cyst is opened to confirm the diagnosis.

Treatment

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

Rarely they may be opened and drained if they are large enough to cause problems with the shape of the cervical canal, which can examinations more difficult.

Support Groups

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.
