BENIGN - Watchful waiting - Cystectomy MALIGNANT - Hysterectomy + bilateral salpingo-oophorectomy + lymph nodes - Chemo/radiotherapy
What is polycystic ovarian syndrome (PCOS)
- PCOS is characterised by excessive androgen production and presence of multiple cysts on the ovaries
Describe the pathophysiology of PCOS
- Excess LH production causes excess ovarian production of androgens (testosterone)
- Insulin resistance also occurs
- Despite the increased levels of LH the raised androgens stop an LH surge occurring so ovulation is not triggered meaning follicles remain as cysts in the ovaries
How might PCOS present
- Excess weight gain
- Male pattern hair (alopecia + facial/chest/back hair)
- Amenorrhoea/oligomenorrhoea
- Chronic pelvic pain
- Acne/oily skin
- Infertility
What investigations might you do in PCOS
- USS of ovaries
- Bloods (testosterone and LH raised), TFTs to rule out thyroid
- ?cortisol
What is the diagnostic criteria for PCOS
- Rotterdam criteria (2 of 3)
1) Polycystic ovaries on USS
2) Clinical or biochemical signs of hyperandrogenism
3) Oligo/anovulation
How would you manage PCOS
Tailored to individual symptoms
Oligo/amenorrhoea (trigger ovulation to dec. cancer risk)
- Combined oral contraceptive or progesterone analogue
Obesity
- Lifestyle advice
- Orlistat / off licence metformin
Infertility (for people wanting to conceive)
- Clomifene +/- metformin

What is a Bartholin’s cyst
- A fluid filled sac within one of the Bartholin’s glands in the vagina
- They secrete mucus to help lubricate vagina, can get blocked leading to a cyst or abscess
