Cervical Polyps: Physical Exam
1. Single or multiple pear-shaped growths may protrude from the cervix into the vaginal canal
2. Usually smooth, soft, reddish purple to cherry red
3. May readily bleed when touched
4. May be small or very large
Cervical Polyps: Differential Diagnoses
1. Endometrial polyps

1. Nabothian Cysts are what?
2. Most often caused when what?
3. Tissue growth can cause what complications?
1. Mucous filled cyst on the surface of the cervix
2. Most often caused when stratified squamous epithelium of the ectocervix grows over the simple columnar epithelium of the endocervix
3. Tissue growth can block the cervical crypts and trap mucous inside the crypts
1. Appear how?
3. Appearance may be related to what?
4. Not considered problematic unless what?
5. May be removed how? 2
1. Appear as firm bumps on the surface
2. Considered harmless and usually resolve on their own
3. Appearance may be related to menses
4. Not considered problematic unless they grow very large and present secondary symptoms
5. May be removed by electrocautery or cryotherapy
1. Pathology in order of prevalence? 3
2. Symptoms? 4
-Adenosquamous, rare types (sarcomas)—6%
-Abnormal vaginal bleeding
-Vaginal discharge—can be watery, mucoid or purulent and malodorous
What does an adenocarcinoma of the cervix look like?
An elevated white and dense lesion overlying columnar epithelium with coarse punctation
Risk Factors for Cervical Cancer
1. Early onset of intercourse (3 term pregnancies)
6. Cigarette smoking (for squamous cell CA)
8. Oral contraceptive use—especially long term (?)
9. Low socioeconomic status (?)
10. Daughter of a mother who took diethylstibestrol (DES) (1970s)
Protective Factors for cervical cancer?
2. Long-term celibacy
3. Life-long mutual monogamy
4. Long-term use of condoms
5. Obtaining regular Pap smears
Most HPV infections are transient—but:
1. Over 50% are cleared in ____ months
2. 80-90% will have resolved within ___ years
3. ____ can be detected in 99.7% of cervical CAs!
4. Generally HPV alone cannot cause cervical CA—it usually takes about ____ from time of infection to presentation of cervical CA
4. 15 yrs
How does HPV cause cancer?
HPV integrates into the human genome & can result in abnormal high grade lesions and cancer
Major factors associated w/ development of HGL and cervical Cancer are?
1. HPV subtype: 18 & 16 (involved in the bulk of cervical CAs)

Diagnosis of Genital HPV
1. Papanicolaou (Pap) smears prepared from cervical or anal scrapings often show cytologic evidence of HPV infection
2. Persistent or atypical lesions should be biopsied and examined by routine histologic methods
3. The most sensitive and specific methods of virology diagnosis, use techniques such as the
-polymerase chain reaction or
-the hybrid capture assay to detect HPV nucleic acids and to identify specific virus types
