Hirsutism In Women

Hirsutism in women is the excessive growth of coarse, dark (terminal) hair in a male-pattern distribution, most commonly caused by androgen excess or increased skin sensitivity to androgens.

Uncovering the hidden agenda: The simulated patient with hirsutism may actually be most worried about infertility, self-image/relationship impact, or fear of cancer. Always ask 「你最擔心嘅係咩?」 and 「今日特別嚟睇嘅原因係咩?」 — "Why today?" often reveals the real RFC.

Case Report Form Answer Builder

  • CC: "Excessive facial / body hair growth for X months/years"
  • HPI high-yield points: onset (gradual vs rapid), duration, distribution (face/chest/abdomen/back), progression, associated menstrual irregularity (oligomenorrhoea/amenorrhoea), weight gain, acne, any virilisation signs (voice change, temporal balding, clitoromegaly), cosmetic measures tried, drug history, family history of hirsutism/PCOS

Examples (choose based on history):

  • "Patient concerned about increasing facial hair affecting self-confidence"
  • "Patient worried excess hair may indicate a hormonal problem"
  • "Patient wants to know if hirsutism is related to difficulty conceiving"
  • Phrase it as the patient's perspective, not a medical diagnosis.

Likely ExampleHow to Write
Ideas"I think it might be hormonal" / "Maybe it's PCOS — I Googled it"Patient thinks her excess hair is due to a hormonal imbalance
Concerns"I'm worried it could be something serious like a tumour" / "I'm worried I can't have children" / "I feel unfeminine and my boyfriend noticed"Patient is concerned about the possibility of a serious cause / concerned about fertility / concerned about appearance and self-esteem
Expectations"I want a blood test" / "I want treatment to reduce the hair" / "I want a referral to a specialist"Patient expects investigation to identify the cause and treatment to reduce hair growth

Polycystic ovary syndrome (PCOS) — the most common cause of hirsutism in reproductive-age women [1][5]

Minimum supporting evidence: hirsutism (modified Ferriman-Gallwey score ≥ 5 in Chinese [1]) + oligomenorrhoea + acne ± obesity. Confirm with LH:FSH ratio > 2.5, raised testosterone, pelvic USS showing polycystic ovaries.

DDxKey Discriminator
1. Idiopathic hirsutismHirsutism with regular menses, normal androgens, often +ve FHx
2. Late-onset (non-classic) CAHYoung onset, raised 17-OH progesterone, family history, sometimes primary amenorrhoea [4]
3. Cushing's syndromeCentral obesity, purple striae, proximal myopathy, moon face, easy bruising, hypertension, DM [2][3]

DomainProblem
BiologicalAndrogen excess causing hirsutism and oligomenorrhoea; associated metabolic risk (insulin resistance, obesity, dyslipidaemia)
PsychologicalBody image distress, low self-esteem, possible depressive symptoms related to altered appearance
SocialImpact on intimate relationships, social embarrassment, potential subfertility affecting family planning

Diagnosis / DDxBest Supporting Physical SignHow to Elicit ItWhy It Supports This Diagnosis
PCOS (most likely)Hirsutism scored by modified Ferriman-Gallwey scale (≥ 5 in Chinese women) [1] + acanthosis nigricans (insulin resistance marker)Inspect 9 body areas for terminal hair (lip, chin, chest, upper/lower abdomen, upper/lower back, upper arm, thigh); inspect axillae/neck for velvety dark patchesTerminal hair in androgen-dependent areas confirms clinical hyperandrogenism; acanthosis nigricans supports insulin resistance seen in PCOS
Cushing's syndromeProximal myopathy — unable to stand from squatting without using hands [2][3]Ask patient to squat and stand up unaided; also look for purple striae > 1 cm wide, thin skin, easy bruisingProximal myopathy is a more specific sign for Cushing's; purple striae and spontaneous bruising also highly suggestive
Late-onset CAHNo reliable single physical sign in brief FM stationCheck for signs of virilisation (clitoromegaly on pelvic exam — unlikely in OSCE); best exam clue is severe hirsutism + acne disproportionate to other features; confirm by serum 17-OH progesterone [4]Elevated early morning 17-OH progesterone is diagnostic; physical signs overlap with PCOS
Androgen-secreting tumourSigns of virilisation: temporal balding, deepened voice, clitoromegaly, increased muscle mass [1]Inspect hairline (temporal recession), listen to voice pitch, examine for clitoromegalyVirilisation is rare in PCOS; its presence should trigger urgent investigation (testosterone, DHEAS, imaging)
Idiopathic hirsutismNo distinguishing physical signNormal BMI, no acne, no virilisation, no acanthosis nigricans; diagnosis of exclusionAbsence of other signs + normal androgens supports idiopathic aetiology

Top Traps That Lose Marks

  1. Confusing hirsutism with hypertrichosis — Hirsutism = androgen-dependent terminal hair in male-pattern distribution. Hypertrichosis = generalised vellus hair growth (non-androgen dependent, e.g. hypothyroidism, drugs like minoxidil, cyclosporine).
  2. Forgetting to ask about medications — Valproate, cyclosporine, danazol, phenytoin, anabolic steroids, and topical/systemic corticosteroids are common culprits.
  3. Missing virilisation signs — Voice change, temporal balding, clitoromegaly, increased muscle mass → red flag for androgen-secreting tumour; requires urgent referral.
  4. Not asking about fertility — This is often the hidden agenda. PCOS is the #1 cause of anovulatory infertility.
  5. Forgetting to ask ICE — Q3 is directly marked. If you don't ask all three, you lose easy marks.
  6. Writing "hormonal imbalance" as the RFC — The RFC should be the patient's reason, not a medical term. E.g., "Worried about increasing facial hair and inability to conceive."

Must-Not-Miss Red Flags → Urgent Referral:

  • Rapid-onset severe hirsutism + virilisation → suspect androgen-secreting tumour → urgent gynaecology/endocrine referral + imaging
  • Total testosterone > 150 ng/dL or DHEAS > 800 μg/dL → tumour workup [1]
  • Features of Cushing's syndrome → 1mg overnight DST → refer endocrinology [2][3]

Shortest Safe Management / Safety-Net Line:

「我會幫你安排驗血(荷爾蒙、血糖)同超聲波。如果你發覺毛突然多好多、把聲變粗、或者月經完全停咗,要盡快返嚟覆診。」 (I'll arrange blood tests — hormones, glucose — and an ultrasound. If the hair suddenly gets much worse, your voice deepens, or your periods stop completely, please come back urgently.)


High Yield Summary

What to ASK: Onset/progression, distribution (Ferriman-Gallwey areas), menstrual history, virilisation signs, weight change, Cushingoid symptoms, galactorrhoea, drug history, FHx, fertility desire, psychosocial impact, and ICE.

What to WRITE:

  • CC: Excessive hair growth in androgen-dependent areas for [duration]
  • Most likely Dx: PCOS (hirsutism + oligomenorrhoea ± acne ± obesity)
  • DDx: Idiopathic hirsutism, late-onset CAH, Cushing's syndrome
  • Biopsychosocial: metabolic risk / body image distress-depression / relationship-fertility-social impact
  • Physical sign: Modified Ferriman-Gallwey score ≥ 5 in Chinese women [1] + acanthosis nigricans

What NOT to MISS:

  • Rapid onset + virilisation = tumour until proven otherwise
  • Always ask about drugs, fertility, and ICE
  • Modified Ferriman-Gallwey score ≥ 5 defines hirsutism in Chinese women [1]
  • Testosterone > 150 ng/dL or DHEAS > 800 μg/dL → suspect tumour [1]
