Female Genital Tract Flashcards
Name the 5 most important infectious agents in vulvitis.
- HPV (condyloma acuminata, VIN)
- HSV
- Gonococcus (gonococcal vulvovaginitis)
- Syphilis (chancre)
- Candida
Smooth white plaques or papules that extend and coalesced. Biopsy reveals: thinning of the epidermis, disappearance of the rete pegs, hydropic degeneration of the basal cells and dermal fibrosis with scant mononuclear inflammation.
Lichen sclerosus
What causes lichen sclerosus?
Unknown.
Quite possibly autoimmune.
NOT a premalignant lesion but afflicted women have a 15% lifetime risk of developing SCCA.
Biopsy of leukoplakia reveals thickened epithelium and significant surface hyperkeratosis. There is significant leukocytic infiltration of the dermis.
Lichen simplex chronicus
In lichen simplex chronicus, this layer of the epidermis is expanded.
Stratum granulosum
Hallmarks of HPV infection
Perinuclear cytoplasmic vacuolization with nuclear angular pleomorphism and koilocytosis
T/F. HPV(+) vulvar intraepithelial neoplasialeads to poorly differentiated squamous cell CA.
True!
Well-differentiated keratinizing squamous cell CA is seen in HPV(-) individuals, with lichen sclerosus.
Red, scaly plaque in the vulva microscopically characterized by the spread of malignant cells within the epithelium, occasionally with invasion of the underlying dermis
Paget Disease of the Vulva
Red granular foci lined by mucus-secreting or ciliated columnar cells in patients whose mothers took diethylstilbestrol
Vaginal adenosis!
More frequent than vaginal clear cell adenoCA
Overgrowth of regenerating squamous epithelium blocks the orifices of the endocervical glands in the transformation zone to produce ___ lined by columnar mucus secreting epithelium
Nabothian cyst
MOST COMMON cause of cervicitis encountered in STDs
Chlamydia trachomatis
Acute nonspecific cervicitis is seen in ___ and is usually caused by ____.
Postpartum women;
Staphylococci, streptococci
The most successful cancer screening test ever developed
Pap smear
High risk HPV subtypes
16, 18, 45, 31
Low risk HPV subtypes
6, 11, 42, 44
Peak age incidence of CIN? of cervical CA?
CIN: 30 years
Cervical CA: 45 (15 yrs after CIN)
5 yr survival rates of Cervical Ca by stage
Stage 0: 100% Stage 1: 90% Stage 2: 82% Stage 3: 35% Stage 4: 10%
Generally, the diagnosis of chronic endometritis requires the presence of ___.
Plasma cells
Histologic diagnosis of endometriosis depends on finding 2 of the following three features within the lesion.
- Endometrial glands
- Endometrial stroma
- Hemosiderin pigment

Quick staging for endometrial CA:
Stage I: Confined to uterus
Stage II: Cervix
Stage III: Organs within true pelvis
Stage IV: Distant mets
Endometrioid tumor arising in the uterus and ovary. Stage?
If synchronous, signifies two separate primary neoplasms. Not necessarily Stage III endometrial disease. Has a favorable prognosis
Principal biochemical abnormality in PCOS
High androgens
High LH
Low FSH
(Androgens converted to estrone in fat; estrone exerts negative feedback on FSH secretion by pituitary.)
The surface covering epithelium of the ovary is multipotential / totipotential / pluripotential or differentiated.
Multipotential (Sex cord/stromal cells are also multipotential).
Does OCP increase or decrease the risk of ovarian CA?
Decrease
K-RAS protein is overexpressed in this subtype of ovarian tumors.
Mucinous cystadenocarcinomas
Majority of hereditary ovarian CA are due to mutations in:
BRCA genes
Most frequent of the ovarian tumors
Serous tumors
Epithelial lining of benign serous ovarian cysts
Tall columnar epithelium
How many percent of benign serous tumors are bilateral? mucinous tumors?
About 25% of benign serous tumors are bilateral. A lesser percentage - 5% - of mucinous tumors are bilateral.
What do you found in the papilla of serous tumors that you do not find in mucinous tumors?
Psammoma bodies
Implantation of mucinous tumor cells in the peritoneum with production of copious amounts of mucin. This is mostly caused by?
Pseudomyxoma peritonei.
Metastasis from the GI tract (appendix)
Three types of mucinous tumors. Which is typically associated with an endometriotic cyst?
3 is associated with an endometriotic cyst.
- Endocervical
- Intestinal
- Mullerian mucinous cystadenoma
