Infections mainly take form of cervicits but may ascend to result in endometritis and salpingitis
Chalmydia trachomatis
Most serious complication of gohorrhea in woman
PID
Infection that begins in the vulva or vagina and spreads upward to involve most structures in the female genial system
PID
Pelvic pain, adnexal tenderness, fever, vaginal discharge
PID
PID with less involvement of the mucosa and tube lumen and more inflammation within the deeper tissue layers is cause by
Staph, streptococci, coliforms and cholstridium prefringens (non-gonococcal)
Multinucleacted cells, intranuclear viral inclusions, “ground-glass” appearance
HSV infection
Smooth white plaques or macules that may coalesce that can cause atrophy or agglutination of the vulva and may cause vaginal orifice constriction
Lichen sclerosus
Marked thinning of vulva epidermis, degeneration of basal cells, hyperkeratosis, sclerotic changes of dermis, bandlike lymphocytic infiltrate underlying the dermis
Lichen sclerosis
Lichen sclerosis sligtly increasea risk of developing
Sq cell carcinoma of the vulva
Result of rubbing or scratching vulva skin w/ leukoplakia, acanthosis, and hyperkeratosis

Basaloid carcinoma
Exophytic papillary architecture and prominent kiolcytic atypia
Warty carcinoma
Sharply circumscribed nodule, MCly on the labia majora or interlabial folds
Papillary hidradenoma
Papillary projections w/ 2 layers: upper layer of columnar secretory cells, deeper layer of flattened myoepithelial cells
Papillary hidradenoma
Puritic, red, crusted, maplike area, usually on the labia majora
Extramammary paget disease
Immunostain for cytokeratin 7
Paget cells
Failure of mullerian duct fusion leads to
Double vagina and double uterus
Red, granular areas made of up columnar, mucinous epi found in the vagina
Vaginal adenosis
Fluid-filled cysts found on the lateral walls of the vagina that are derived from woffian duct rests
Gartner duct cysts
Virtually all primary carcinomas of the vagina are
Sq cell carcinomas, ass’d with high risk HPV
Greatest risk factor for developing sq cell carcinoma of the vagina

embryonal rhabdomyosarcoma
Loose fibromyxomatous stroma covered by mucus-secreting endo cervical glands, often accompanied by inflammation
Endocervical polyps
In the cervix, HPV infects
- immature basal cells of the sq epi in areas of epi breaks
- metaplastic sq cells at the squamocolumnar junction
Viral proteins of HPV responsible for carcinogenic capabilities
E6 and E7
Binds hypophosphorlyated form of RB and promotes its degresdation , and inhibits p21 and p27
Viral protein E7
Binds p53 and promotes it’s degradation, upregulates telomerase
Viral protein E6
High level of viral replication, mild alterations in the growth of host cells, most cases regress spontaneously
LSIL
Progressive dysregulation of the cell cycle, increased cellular proliferation, decreased/arrested epi maturation, lower rate of viral replication, high risk of progression to carcinoma
HSIL
