Q

condylomata acuminata

A

sexually transmitted “venereal warts”
d/t HPV 6, 11
verrucous proliferation of stratified squamous epithelium - acanthosis w hyperkeratosis, parakeratosis, koilocytic atypia (raisinoid nuclei w perinuclear vacuoles)
*not pre-malignant, may regress

Q

classic vulvar intraepithelial neoplasia

A

precursor to poorly differentiated basaloid and warty squamous cell carcinomas
90% a/w HPV 16, 18
in middle-aged females, smokes
multifocal erythematous plaque with scaling

Q

classic VIN histo

A

acanthosis, hyperkeratosis, parakeratosis

Q

keratinizing squamous cell carcinoma

A

common in 80s, esp w lichen sclerosus or squamous cell hyperplasia
dev from diff VIN
*good prognosis if caught early (less than 2cm lesion = 90% 5 yr survival), but LN involvement = less than 10%

Q

Paget’s disease of vulva

A

aka extramammary Paget’s
looks like breast Paget’s but not a/w invasive cancer, confined to epidermis
red, scaling lesion
single or small groups of neoplastic cells in epidermis surrounded by halo, granular PAS+ cytoplasmic mucin (diff from melanoma)

17
Q

vaginal epithelial atrophy

A

nonkeratinizing stratified squamous mucosa becomes glycogenated w estrogen
post-menopause lack of estrogen -> atrophy of epithelium -> dyspareunia and infection

18
Q

vaginitis cause

A

usually d/t disruption of normal flora by abx, pregnancy, or DM -> commensals become pathogenic

19
Q

3 main types of vaginitis and clinical features

A

1) yeast - Candida albicans (thick white discharge)
2) bacterial - Gardnerella (thin grey milky), Chlamydia
3) protozoan - Trichomonas (thin green frothy)

20
Q

vaginal malignancies

A

rare: primary squamous cell carcinoma, d/t HPV and VAIN
very rare: clear cell adenocarcinoma, embryonal rhabdomyosarcoma, melanoma
*m/c is invasion by adjacent organs (uterus, rectum, bladder)

21
Q

vaginal clear cell adenocarcinoma

A

15-20 yo whose mothers were treated with DES in pregnancy (prevent miscarriage)
have adenosis (glandular columnar epithelium) as precursor that may rarely transform
upper 1/3rd of anterior vaginal wall
good prognosis

22
Q

embryonal rhabdomyosarcoma

A

aka sarcoma botryoides

infants/ kids

23
Q

Nabothian cyst

A

forms when gland openings in cervix are obstructed, may be d/t squamous metaplasia

24
Q

cervicitis

A

common, presents w discharge

acute: usually post-partum, rare (staph, strep)
chronic: STDs (m/c Chlamydia)

25
Q

cervical verruca

A

benign condylomata d/t HPV 6, 11, 42, 44

26
Q

endocervical polyps

A

present w bleeding
loose fibromyxomatous stroma w dilated glands and inflammatory cells
may undergo squamous metaplasia or ulcerate
*no malignant potential

27
Q

cervical dysplasia

A

arises in transformation zone, m/c cause: HPV 16, 18 - integrates into host DNA (E6 p53 and E7 Rb)
precursor to invasive squamous carcinoma - higher grade = greater cancer risk, less time to develop

28
Q

grading of cervical dysplasia

A

biopsy for CIN
CIN1/LSIL: koilocytic change in basal 1/3; 60% regress
CIN2/HSIL: pleomorphism and mitoses in middle 1/3 - treat
CIN3/CIS: full thickness
Pap smear - LSIL or HSIL

29
Q

cervical cancer

A

m/c: squamous cell, other types (adeno) may also be HPV-related
d/t HPV 16, 18, 31, 33, 58
mutation in LKB1 (Peutz-Jeghers syndrome) in over 20% tumors
usually mid-older women
tx: cone biopsy or hysterectomy

30
Q

stages of cervical cancer

A

0 - CIS/CIN3
1 - confined to cervix
2 - beyond cervix but not to pelvic wall or lower 1/3rd vagina
3 - extends into pelvic wall and/or lower 1/3rd vagina
4 - extends beyond true pelvis, involves bladder or rectal mucosa, mets
*death d/t local invasion
