Symptoms of cervical ectropions
Normally asyx
PCB, vaginal discharge
Treatment of ectropion
Cryotherapy w/out anaesthesia once smear/colposcopy -ve for malignancy
Causes of cervicitis (acute and chronic)
Acute: STD, ulceration and infection often prolapsed
Chronic: inflammation/infection ie of ectropion
Treatment of cervicitis
Inflammatory smear + discharge
Tx with avulsion but still investigate bleeding
Cervical polyps: epi, syx and tx
Common after 40, usually
What is a nabothian follicle?
Squamous epithelium over columnar = blocks glands –> white glands and opaque swelling on ectocervix
Tx if syx
Definition and Classification of CIN
Definition: atypical cells in Sq epi - larger nuclei + dyskaryosis (atypia)
I - mild - lower 1/3 of epithelium
II - moderate - lower 2/3
III - severe - full thickness (malignant like cells without invasion)
Malignancy = invasion of Basement membrane
Epi of CIN
1/3 of III will get cervical cancer within 10 years
Peak 25-29
HPV 16, 18, 31, 33 - (16+18 vaccinated now before first sex)
OCP and smoking
Immunodef ie steroids or HIV
Pathology of CIN
Columnar to Sq in TZ
HPV turns off tumour suppressor genes and hides cells from immune system
NB CIN is premalignant and predicts risk of developing cervical cancer
Screening schedule for CIN
Smear every 3 years from 25-49, 5 years 50-64, >65 if no smear since 50 or previously abnormal
80% acception rate
Smear test procedure
Cusco speculum and brush –> liquid based cytology (only 2.5% failure) + HPV test
Smear test results (mild/CGIN)
Detects atypical cells not histo abnormalities
Mild = HPV test –> high risk HPV = colposcopy, low/no HPV = back to normal schedule of 3/5y
CGIN = cone biopsy
Smear test results (II/III)
Colposcopy w/ tx - TZ excised w/diathermy/LLETZ = dx and tx
Risk of haemorrhage and preterm delivery
Cervical cancer: Epidemiology
Peak 30s/80s esp 25-29
90% SCC, 10% adenocarcinoma (worse prognosis)
All have HPV - same risks as CIN as it’s premalignant
Inadequate screening and FHx are common
What is a cervical ectropion and what is the cause?
Columnar epithelium visible around the os caused by eversion in pregnancy or puberty
Epidemiology of cervical cancer
Peak 30s and 80s (25-49, esp 25-29)
90% SCC 10% adeno from columnar: worse prognosis
Aetiology of cervical cancer
HPV in ALL cervical cancer
HIV/immunodef
smoking
inadequate screening
Clinical features of cervical cancer: Hx and Ex
Occult: asyx but dx on biopsy/LLETZ
Hx: PCB, IMB, PMB, offensive discharge. PAIN is UNCOMMON
Late: uraemia and haematuria, rectal bleeding and pain (ureters, bladder, rectum and nerves)
Ex: ulcer or mass on cervix or may look normal
Staging of cervical cancer
1ai: dx on microscopy: invasion 4cm diameter
2ai: upper 2/3 vagina w/o parametrial involvement 4cm
2b: parametrium
3: lower vagina or pelvic wall or ureteric obstruction
4: bladder or rectum or pelvis
Anatomy of uterus
Myometrium (smooth muscle) and Endometrium (glandular)
Supported by uterosacral and cardinal (like cervix)
Broad = continuous with pelvic side wall and F tubes
Round = little support but holds blood supply
EM responds to oestrogen and progesterone, basal + spiral arterioles
Fibroids Pathology and Epidemiology
25% of women, esp near menopause, decreased in nulliparous + OCP - oestrogen driven, regress postmenopausally
Benign tumour of the myometrium
Variable size, intramural, subserosal, submucosal (polyp)
Fibroid syx
50% asyx - syx due to size
30% get HMB, IMB if submucosal/polypoid
Pain is rare unless torsion, sarcoma or red degeneration
Urinary if pressure on tract
Reduced fertility esp implantation and tube blocking
Progression of fibroids
Slow growing, calcify post menopausally, HRT increases growth
Degenerate if poor blood supply - red = haemorrhage and necrosis, hyaline = fluid filled
Fibroids in pregnancy
Red degeneration, premature, malpresentation, abnormal lie, obstruction, PPH
Don’t remove at section due to bleeding
