Definition
A nabothian cyst is a cystic lesion at the transformation zone between the squamous epithelium of the ectocervix and the columnar epithelium of the endocervical canal.
A nabothian cyst is caused by growth of the squamous epithelium over the columnar epithelium.
The result is trapping of cervical mucus produced in the crypts of the columnar epithelium. The structural change is characterized by a cystic space filled with mucus and covered by squamous epithelium at the cervical transformation zone.
The functional change is usually minimal.
Clinically most women with a nabothian cyst are asymptomatic and present during routine gynecologic examination.
Diagnosis is made based on clinical appearance.
No treatment is required, as nabothian cysts are benign. Many regress without intervention.

The ultrasound is from a 40 year old patient who presents with pelvic discomfort . Nabothian cysts in the cervix are of incidental note. They are cystic in nature demonstaring anechogenicity, through transmission, and backwall enhancement. The examination was otherwise normal. Courtesy Ashley Davidoff MD Copyright 2010 49463 |
