1. Pathology of the Female Repro Tract Flashcards
Histology of the Vulva and Vagina
Stratified Squamous epithelium
How does the vagina change during puberty?
Rise in oestrogen from ovary -stimulates maturation of squamous cells
Glycogen is formed within mature squamous epithelial cells
Glycogen in cells shed from the surface is a substrate for vaginal anaerobic organisms (dominated by lactobacilli)
Lactobacilli produce lactic acid - vaginal pH <4.5
Histology of ectocervix
stratified squamous epithelium
Histology of endocervix
Single layer of tall, mucin producing columnar cells
Formation of the transformation zone
During puberty the cervix changes shape
The lips of the cervix grow
The distal end of the endocervix opens
Endocervical mucosa becomes exposed to the vaginal environment
Histology of endometrium in the proliferative phase before ovulation
Tubular glands
Specialised stroma
Blood vessels
Mitoses in glands
Histology of endometrium in the secretory phase after ovulation
Cork screw glands
Specialised stroma
Blood vessels
Secretions in glands
What is a fibroid?
Leiomyoma of the myometrium
- benign neoplasm of smooth muscle
- localised
- slow growing
- closely resembles parent tissue
What is the difference between carcinoma and dysplasia?
invasion through basement membrane
High risk HPV
16, 18
Low risk HPV
6,11
