Documented Premalignant Lesions
• Vulva: Yes
– VIN
• Vagina: Yes
– VAIN
• Cervix: Yes
– CIN
• Endometrium: Yes
– For Type I cancers, EIN
• Fallopian Tube: Yes
– STIC
• Ovary: Probably not, or No
Treatment Selection
• Risk of progression if untreated?
• Success of treatment?
• Toxicity/complications of therapy?
• Extent or size of lesion?
• Presence or absence of symptoms?
Case #1
45 year old renal transplant patient, smokes 2
ppd. Complains of vulvar pruritis.
Exam demonstrates-
Vulvar Intraepithelial Neoplasia
• VIN I: does not exist
• VIN: Encompasses VIN 2 & 3
– VIN- Usual Type (warty, basaloid, mixed)
• Associated with invasive squamous carcinoma of
warty or basaloid type
– VIN-Differentiated type
• More common in older women, with lichen
sclerosus.
• Associated with keratinizing squamous carcinoma.
• Not HPV related

Treatment Options
• Observation- In the face of repeated recurrences, or
something else will do her in first.
• Excision- Primary closure or skin graft
• Laser vaporization- Multiple lesions, large, or at the
introitus
• Topical therapy ( 5-FU), Imiquimod
Case #1
45 year old renal transplant patient, smokes 2
ppd. Complains of vulvar pruritis.
Exam demonstrates- Hypo and hyper
pigmented vulvar lesions.
Bx = VIN/CIS with probable early invasion.
Treatment Options??
Case # 2
77 year old with vulvar pruritis and multiple
treatments for yeast infection.
Exam = Erythematous, excoriated epithelium
with “cake frosting” coating.
Vulvar Biopsy = Paget’s disease of the vulva
Workup and treatment??
Treatment Options
• Excision- Primary
• Laser vaporization- Poor choice due to
gland involvement
• Topical therapy ( 5-FU)-Rarely
Case # 3
38 year old G3P3, Reports a vaginal hysterectomy
for a precancerous condition three years ago.
Pap = HSIL
Colposcopy = Thickened, acetowhite epithelium at
the vaginal apex.
Treatment Options
• Excision- I wouldn’t unless I suspected invasion.
• Laser vaporization- Yep
• Topical therapy ( 5-FU), Imiquimod- Last
resort
Case # 4
32 year old G2P2 with HSIL Pap.
Colposcopy = Acetowhite epithelium with
punctuation. Large transformation zone.
ECC and Cervical Biopsies performed.
What is a Transformation Zone??
Case # 4
32 year old G2P2 with HSIL Pap.
Colposcopy = Acetowhite epithelium with
punctuation. Large transformation zone.
ECC-neg, CxBx-CIN III
Treatment Options??
Treatment Options ??
• Observation ?
• Excision ?
• Laser vaporization, Cryotherapy ?
• Hysterectomy ?
Treatment of CIN 2,3
• LEEP, or conization may be used whenever
treatment is appropriate.
• Cryotherapy of Laser vaporization should be used
only after rigorously excluding invasive cancer.
• Hysterectomy is unacceptable as primary therapy
for CIN 2+
ACOG Practice Bulletin 140, December, 2013
Case # 4
32 year old G2P2 with HSIL Pap.
Colposcopy = Acetowhite epithelium with
punctuation. Large transformation zone.
What if the biopsy had shown
adenocarcinoma in situ of the cervix?
