Vulvovaginal and Cervical Pathology Flashcards
What are the layers of the normal ectocervix?
Exfoliating cells Superficial cells Intermediate cells Parabasal cells Basal cells Basement membrane
Describe the normal endocervix?
Single layer glandular epithelium
What is the transformation zone of the cervix?
Squamo-columnar junction between the ectocervical (squamous) and endocervical (columnar epithelium)
When does the transformation zone of the cervix alter in position?
As a physiological response e.g. to menarche, pregnancy, menopause
Define cervical erosion
Physiological exposure of delicate endocervical epithelium to acid environment of vagina leads to physiological squamous metaplasia
What is a nabothian cyst?
A physiologically distended endocervical gland, usually with overlying squamous metaplasia
What are the causes of cervicitis?
Chlamydia
Herpes Simplex
Follicular cervicitis
What damage can cervicitis cause?

Are cervical polyps premalignant?
No
What is main risk factors for Cervical cancer

Vulnerability of SC junction in early reproductive life (young first intercourse, long term OCP use)
Smoking
Immunosuppression
Which types of HPV cause genital warts?
6+11
How do genital warts present?
Thickened papillomatous squamous epithelium with cytoplasmic vacuolation
How long does HPV infection take to create high grade CIN?
6 months-3years
