Pruritis**
Dysuria
Dyspareunia
6

25
Neoplasticism cells confined to squamous epithelium
Vulvar Intraepithelial Neoplasia (VIN)
26
What are the classifications of VIN
VIN 1, 2, or 3 (just like CIN)
But really, you could eliminated VIN 1 and combine 2/3 as the true precursors to vulvar cancer
VIN 2/3 are further differentiated into VIN-U and VIN-D
27
VIN 2/3 are subdivided into _____ and ______ based on _____.
VIN-U (usual type)
VIN-D (differentiated)
Based on morphologic manifestations, HPV content, and clinical characteristics
28

VIN-U
29
Which type of VIN:
Seen in younger women
VIN-U
30

31
How is VIN-U diagnosed?
Vulvar colposcopy
3-5% acetic acid applied, wait 3-5 min, maybe reapply
Avoid using acetic acid in areas of inflammation and breaks in epithelium
32
Colposcopy findings consistent with VIN-U
Lesions are raised or flat
Range in color from gray to white or red to black
Must biopsy all pigmented (or hypopigmented) lesions****
33

Vulvar burning and pruritis in 50%
34
Why are colposcopies mandatory for VIN-U?
Associated with high grade CIN

VIN-D
42
What is the treatment for VIN-D?
Surgical excision
NO CO2 laser - you want clear margins
43
What is the recommended follow up for VIN?
If VIN-U, vaccination with Gardasil
Women w/ a hx of VIN should be considered at risk for recurrence throughout lifetime
Post treatment f/u includes colposcopy at 6 and 12 months then annually thereafter

Radiation therapy indicated with lymph node spread
55
What has to be present for a woman to develop VaIN?

Early onset of sexual history
History of CIN III
58
What is the pathogenesis of VaIN?
HPV EXPOSURE IS A MUST!
Development of VaIN following HPV exposure requires greater period of time

Upper 1/3 of the vagina
60

VaIN 1 = benign viral proliferation
VaIN 2 = intermediate risk
VaIN 3 = true precursor to vaginal cancer
61
How do you diagnose VaIN?

70
Polycystic Ovarian Syndrome results from...
Abnormal androgen and estrogen metabolism —> unregulated androgen production —> high serum testosterone, androstenedione, and DHEA
71
What is the relationship between PCOS and insulin?
PCOS —> insulin resistance and hyper insulin emit
Increased insulin alters gonadotropin (FSH/LH) effects on ovarian function
Increased insulin decreases synthesis of sex hormone binding globulin (SHBG) and insulin-like growth factor
72
What happens to adiponectin in PCOS patients?
Decreased
Adiponectin regulates lipid metabolism and glucose levels, so decreased adiponectin further exacerbates PCOS symptoms
73
What role do gonadotropins play in PCOS?
Increased LH stimulates theca cells to produce androgens
FSH is depressed (b/c negative feedback) —> decreased aromatase in the ovary —> decrecreased conversion of androgens to estrogens
74
In PCOS, increased androgens released from the ovary are converted to estrogen by...
Adipose tissue
This causes negative feedback to anterior pituatary and further decrease in FSH production
75
In PCOS, increased circulating insulin stimulates...
The ovary to produce more androgens —> elevated circulating free testosterone
76
Most common symptom of PCOS

79
What is the Rotterdam Criteria of 2003 for PCOS?
2/3 must be present after exclusion of related disorders:
• Oligomenorrhea
• Clinical or biochemical signs of hyperandrogrenism
• Polycystic ovaries
Did not replace NIH definition, just expanded it to include polycystic ovaries
80
Ultrasound findings in PCOS
Presence of >12 follicles in each ovary 2-9mm
“String of pearls” appearance
Ovarian volume >10ml
No evidence of dominant follicle/corpus luteum
81
What lab do you order first if suspecting PCOS?
