    Correct

    • You are called to a delivery as the midwife is concerned about CTG changes. She suggests a fetal blood sample (FBS). You inspect the cervix. At what dilatation would you NOT perform FBS?

      Your Answer: Less than 3cm

      Explanation:

      Indications for FBS:
      1. Pathological CTG in labour (cervix dilated >3 cm)
      2. Suspected acidosis in labour (cervix dilated >3 cm)
      Contraindications to FBS:
      – Maternal infection e.g. HIV, HSV and Hepatitis
      – Known fetal coagulopathy
      – Prematurity (< 34 weeks gestation)
      – Acute fetal compromise

    • What is the mechanism of action of Oxytetracycline?

      Your Answer: inhibit peptidoglycan cross-links in bacterial cell wall

      Correct Answer: Binds to 30S subunit of microbial ribosomes blocking attachment of aminoacyl-tRNA to the A site on the ribosome

      Explanation:

      Tetracycline is classified as a broad spectrum antibiotic. It is a bacteriostatic inhibitor of protein synthesis acting at the ribosomal level. Tetracycline binds to the 30s ribosomal subunit preventing the binding of the aminoacidic charged T-RNA to the ribosome-mRNA complex.

    Correct

    • You see a patient in antenatal clinic who is concerned that she has never had chicken pox and may catch it during pregnancy. You check her Varicella status and she is non-immune. She asks you about vaccination. What type of vaccine is the varicella vaccine?

      Your Answer: Attenuated

      Explanation:

      Varicella is a live vaccine. The recent RCOG green top guidelines suggest vaccine can be considered postpartum or pre pregnancy but NOT whilst pregnant. In the non-immune pregnant woman they should be advised to avoid contact with people with chickenpox or shingles and to contact a healthcare professional promptly if exposed. If they have a significant exposure VZIG should be offered as soon as possible.

    Incorrect

    • What is the Gold standard investigation to diagnose abnormal uterine bleeding?

      Your Answer: Transvaginal ultrasound

      Correct Answer: Hysteroscopy along with dilatation and curettage

      Explanation:

      During the last decade hysteroscopy has become the tool of choice for the evaluation of the endometrial cavity, including for assessment of abnormal uterine bleeding (AUB). Many clinicians would consider that, in most patients, the combination of transvaginal sonography and out-patient endometrial biopsy with diagnostic hysteroscopy could replace the need for dilation and curettage. Hysteroscopy was reported to have sensitivity, specificity, negative predictive value and positive predictive value of 94.2, 88.8, 96.3 and 83.1% respectively, in predicting normal or abnormal endometrial histopathology.

      The highest accuracy of hysteroscopy was in diagnosing endometrial polyps, whereas the worst result was in estimating hyperplasia. Therefore, since the incidence of focal lesions in patients with AUB is high, it seems that the most beneficial approach is to proceed with hysteroscopy complemented by endometrial biopsy early in the assessment of AUB.

      Transabdominal and transvaginal ultrasounds can be used but are inferior to hysteroscopy.

      Coagulation profile can only diagnose possible coagulopathies and pregnancy test can only diagnose pregnancy. All other causes can not be identified with these laboratory investigations.

    Correct

    • A 25 year old primigravida with a regular cycle had her last menstrual period on June 30th. Therefore the expected date of delivery (EDD) is approximately when the following year:

      Your Answer: 7-Apr

      Explanation:

      Expected date of delivery (EDD) is a calculated from the first day of the woman’s last menstrual period. If her periods are regular i.e., 28-day menstrual cycle, Naegele’s rule may be used. Naegele’s rule involves a simple calculation: add seven days to the first day of your LMP and then subtract three months. e.g. 30 June + 7 days = 7 July, minus 3 months = 7 April.

    Incorrect

    • Of the following, which one has the greatest effect on the relative risk of developing endometrial carcinoma?

      Your Answer: Infertility

      Correct Answer: Polycystic ovary syndrome

      Explanation:

      The factor associated with the greatest relative risk for endometrial carcinoma is polycystic ovary syndrome, which has a relative risk of 75. The use of long-term high doses of postmenopausal oestrogen carries an estimated risk of 10-20. Living in North America or Europe also has an estimated risk of 10-20.

      A lower relative risk is associated with nulliparity, obesity, infertility, late menopause, older age, and white race- The relative risk associated with these factors falls into the range of 2-5. Early menarche, higher education or income levels, menstrual irregularities, and a history of diabetes, hypertension, gall bladder disease, or thyroid disease have a relative risk of around 1.5-2.0.

    • A 37 year old lady attends clinic following laparotomy and unilateral oophorectomy. The histology shows mucin vacuoles. What type of tumour would this be consistent with?

      Your Answer: Mucinous

      Explanation:

      Mucinous tumours are cystic masses which are indistinguishable from the serous tumours on gross examination except by its contents. On histology it is lined with mucin producing epithelium – mucin vacuoles whereas serous tumours have psammoma bodies. Malignant tumours are characterised by the presence of architectural complexity, cellular stratification, stromal invasion and cytological atypia.

    Correct

    • A 25-year-old woman comes to your clinic for advice as she is 20 weeks pregnant and was found to have thyrotoxicosis with mild enlargement of the thyroid gland.

      What other investigation will you consider to be done in this patient?

      Your Answer: Ultrasound thyroid gland

      Explanation:

      A 20 weeks pregnant patient has developed goitre along with thyrotoxicosis, where the diagnosis of thyrotoxicosis has already been established.
      Ultrasound of the thyroid and a radioisotope scan to differentiate between “hot” and “cold” nodules are the confirming investigations for goitre. A nodule composed of cells that do not make thyroid hormone and the nodule which produces too much thyroid hormone are respectively called as cold and “hot” nodules.

      Due to the risk of fetal uptake of the isotope which leads to the damage of fetal thyroid, radioisotope or radionuclide Technetium uptake scan is contraindicated in pregnancy.

      Fine needle aspiration cytology is required to establish a histopathological diagnosis in case of all cold nodules.

      So ultrasound of the thyroid gland is the mandatory investigation to be done in this case as it will show diffuse enlargement, characteristic of the autoimmune disease, or multinodularity, which is suggestive of autonomous multinodular goitre.

    • A 27-year-old female G1P1 presents with her husband because she has not been breastfeeding her baby 24 hours though she had previously stated she intended exclusive breastfeeding for the first 3 months. She feels sad most of the time and her mood has been very low for the past 2 weeks, she has trouble sleeping at night and feels tired all day. She complains that her husband doesn’t seem to know how to help. For the past 24 hours she feels like she is not fit to be a mother and doesn’t want to feed the baby anymore. She has been frightened by thoughts to harm herself and the baby. Her baby is 7 weeks old.
      In addition to antidepressant medication, which of the following treatment is most appropriate for this patient?

      Your Answer: Peer support

      Correct Answer: Electroconvulsive therapy

      Explanation:

      This patient presents because of significant mood changes since she gave birth to her child: she is sad most of times and she is having guilt feelings about her adequacy for motherhood- She is also complaining of insomnia, tiredness, and even some suicidal ideation. These symptoms are highly suggestive postpartum depression. This should be differentiated from postpartum blues, which usually present within the first 2 weeks and last for few days. This patient’s symptoms started 5 weeks postpartum. Postpartum depression usually presents within the first 6 weeks to the first year postpartum.

      Postpartum depression is the most common complication of childbearing and affects the mother, the child, and relationship with the partner. It is diagnosed the same way as major depressive disorder in other patients. Since untreated postpartum depression can have long-term effects on the mother and the child, appropriate therapy should be undertaken as soon as possible- Antidepressant medications such as sertraline can be used to treat postpartum depression. In a patient who has suicidal ideation, electroconvulsive therapy has a more rapid and effective action than medication and should be considered in these patients.

      → Cognitive behavioural therapy is effective in women with mild to moderate postpartum depression; it would not be a good choice in this patient with suicidal ideation and at risk of harming the baby.
      → Estrogen therapy used alone or in combination with antidepressant, has been shown to significantly reduce the symptoms of postpartum depression; however, it would not be the most appropriate choice in a patient with suicidal ideation.
      → Peer support has shown equivocal results in various studies even though most postpartum patients report that lacking an intimate friend or confidant or facing social isolation are factors leading to depression.
      → Non-directive counselling also known as ”listening visits“ has been found to be effective in postpartum patients, though the studies that were conducted are deemed to be of small sample and larger studies still need to be done to validate these findings. It would not be an appropriate choice for this patient with suicidal ideation.

    • A 30-year-old woman who is at 38 weeks gestation presented to the emergency department due to complaints of not feeling fetal movements since yesterday. Upon investigations, fetal demise was confirmed. Induced delivery was done and she gave birth to a dead foetus.

      Which of the following is least likely to reveal the cause of the fetal death?

      Your Answer: Autopsy of the foetus

      Correct Answer: Chromosomal analysis of the mother

      Explanation:

      Stillbirth has many causes: intrapartum complications, hypertension, diabetes, infection, congenital and genetic abnormalities, placental dysfunction, and pregnancy continuing beyond forty weeks.

      In 5% of normal-appearing stillborns, a chromosomal abnormality will be detectable. With an autopsy and a chromosomal study, up to 35% of stillborns are found to have a major structural pathology, and 8% have abnormal chromosomes. After a complete evaluation, term stillbirth remains unexplained about 30% of the time. The chance of finding a cause is impacted by the age of the foetus, the experience of the caregiver, and the thoroughness of the exam. Chromosome testing for aneuploidy should be offered for all stillbirths to confirm or to seek a cause of the stillbirth. Genetic amniocentesis or chorionic villus sampling before delivery offers the highest yield.

    Correct

    • Fetal urine production starts at what gestation?

      Your Answer: 8-11 weeks

      Explanation:

      Fetal urine contributes significantly to amniotic fluid production in the second trimester of pregnancy. As early as 8-11 weeks, urine production begins and can be observed in the fetal bladder on ultrasound scans. The urine creates a hypotonic fluid which contains increasing concentrations of urea and creatinine. By term, a foetus produces about 800 ml of urine a day, of which 250ml is eliminated through fetal swallowing.

    Correct

    • Which of the following describes the change from cervical columnar epithelium to stratified squamous epithelium?

      Your Answer: Metaplasia

      Explanation:

      Cells adapt to external stressors in a variety of ways. A cell can either undergo hypertrophy or hyperplasia to overcome the stress, or atrophy if unable to overcome the stress. Metaplasia occurs when fully differentiated cell lines transform into another fully differentiated cell type to adapt to a new external environment. The replacement of columnar epithelium of the cervix to a stratified squamous epithelium occurs in the squamocolumnar transformation zone in response to the exposure of an everted ectocervix to the acidic pH of the vagina at puberty and first pregnancy. Carcinoma in situ is thought to involve the immature metaplastic cells in this region.

    • A 28-year-old presented with vaginal bleeding after a 6-week duration of amenorrhea. The bleeding was described to be heavier than ever compared with her previous periods. Upon interview, it was noted that her menstrual cycles was ranging from 4 to 6 weeks.

      A urine pregnancy test was performed and the result was positive. Upon vaginal examination, it was noted that her cervical os is closed. An endovaginal ultrasound was performed and the results showed an endometrial thickness of 12mm and an empty uterus. There was also clear adnexa, and no fluid in the pouch of Douglas was seen. A cyst in the corpus luteum of the left ovary was also noted.

      Which of the following is most likely the diagnosis of the patient?

      Your Answer: Complete abortion

      Explanation:

      Complete abortion is defined as a ‘complete’ passage of all conception products.

      The first day of the last menstrual period and findings on any prior ultrasounds should be determined to establish the gestational age and location of the pregnancy. An abdominal exam should be performed to assess for peritoneal signs that might indicate a ruptured ectopic pregnancy or extra-uterine extension of a septic abortion. Lastly, a pelvic exam is central to the evaluation of suspected miscarriage. It should include both speculum-facilitated visualization of the cervix and a bimanual examination to assess for cervical motion tenderness that may indicate a septic abortion or an adnexal mass that may herald ectopic pregnancy.

      Early pregnancy loss takes many different forms. In missed abortion, there is asymptomatic or ‘missed’ death of the embryo or foetus without sufficient uterine contractions to push out the products of conception. In contrast, threatened abortion is characterized by symptomatic, ‘threatened’ expulsion of the products of conception, yet the cervical os remains closed, and the embryo or foetus remains viable.

      Although there is a lack of consensus, complete abortion is often defined as the absence of a gestational sac on ultrasound with an endometrial stripe thickness of less than 30 mm.

      Explanation:

      In the foetus, the hypogastric artery ascends along the side of the bladder, and runs upward on the back of the anterior wall of the abdomen to the umbilicus, converging toward its fellow of the opposite side. Having passed through the umbilical opening, the two arteries, now termed umbilical, enter the umbilical cord, where they are coiled around the umbilical vein, and ultimately ramify in the placenta.

Patient has had no vaginal bleeding or cramping, no chronic medical conditions, and her only medication is a daily dose of prenatal vitamin. Patient follows a vegan diet and drinks 2 cups of coffee in the morning, also she is an avid runner who runs 5 miles most days. Patient does not use tobacco, alcohol or any other illicit drugs. 

      On physical examination her vital signs are normal, with a pre-pregnancy BMI of 22 kg/m2.
      Transvaginal ultrasound shows a single intrauterine gestation with a heart rate of 155/min. 

      Among the following possible lifestyle modifications needed during pregnancy, which is the most appropriate recommendation for this patient?

      Your Answer: Eliminate caffeine consumption from diet

      Correct Answer: Increase caloric intake by about 350 kcal/day

      Explanation:

      Nutrition in pregnancy
      Weight gain must be:
      – In patients <18.5 kg/m2, there should be an increase of 12.7 - 18 kg (28-40 lb)
      – In patients 18.5 – 24.9 kg/m2 there should be an increase of 11.4 – 15.9 kg (25-35 lb)
      – In patients 25 – 29.9 kg/m2 there should be an increase of 6.8 – 11.4 kg (15-25 lb)
      – In patients ≥30 kg/m2 there should be an increase of 5 – 9 kg (11-20 lb)

      Supplementation required:
      – Intake of daily prenatal vitamin
      – Additional specific supplements as indicated
      – Avoidance of harmful substances like drugs, alcohol, etc
      – Substance abuse counseling
      – Avoidance of fish with high mercury levels
      – Moderating caffeine intake

      Food safety:
      – Avoid undercooked meat, fish & eggs
      – Clean raw fruits & vegetables before consuming
      – Avoid unpasteurized dairy products

      Nutrition in pregnancy is addressed at the initial prenatal visit based on pre-pregnancy BMI. Appropriate weight gain for a women with a normal pre-pregnancy BMI of 18.5 – 24.9 kg/m2 should be 11.4 – 15.9 kg (25-35 lb) during pregnancy. This weight gain is equivalent to the increasing caloric intake of 350 kcal/day during the second and 450 kcal/day during the third trimesters.  Patients following any specific diets like veganism can continue their usual diet throughout pregnancy as long as it contains a well-balanced quantity of protein, carbohydrates and fats.

      Vitamin and mineral supplementation during pregnancy is a single, daily prenatal vitamin recommended for majority of pregnant women as it helps to fulfill most of the daily vitamin and mineral supplementation requirements. In case of patients with vitamin or mineral deficiencies like iron, calcium, etc, a specific supplementation of the deficit vitamin/mineral only is required rather than multiple prenatal vitamins to avoid consuming harmful amounts of other vitamins like vitamin A.  Vegans, who are at risk for some vitamin and mineral deficiencies like vitamin B12, calcium, iron, etc, secondary to lack of meat consumption, may require supplementation.

      Pregnant women are counselled on avoidance of harmful substances like alcohol, drugs, etc and substances like fish with high mercury levels.  Although high caffeine intake during pregnancy can be harmful, a moderate intake ie, 1 or 2 cups of coffee a day is thought to be safe.

      Safe handling of food is important because some food products are found to result in congenital infection and intrauterine fetal demise. Patients are also counselled to avoid undercooked meat, fish, and eggs; to thoroughly clean raw fruits and vegetables and to avoid consumption of unpasteurized dairy products.

      By maintaining a proper maternal nutrition during pregnancy, patients are provide appropriate nutrition to the fetal and thereby reducing the risk of pregnancy related complications like low birth weight, preterm delivery, etc.

      Pregnant patients are counseled to avoid exercises like contact sports, downhill skiing, etc which increases the risk of abdominal trauma resulting in increased risk of placental abruption. But those patients with an uncomplicated pregnancy, who are already accustomed with long-duration, high-intensity exercise like running 5 miles/day, as in the given case, can continue with their regimen if tolerated.

      Proper nutrition in pregnancy includes appropriate weight gain, supplementation of vitamins and minerals, avoidance of any harmful substances, and safe handling of food. Patients with a normal pre-pregnancy BMI should gain around 11.4-15.9 kg (25-35 lb) during pregnancy by increasing their caloric intake by 350 kcal/day in the second and 450 kcal/day in the third trimesters.

      Correct Answer: Aspirin & heparin

      Explanation:

      The syndrome with which the woman was diagnosed is an autoimmune, hypercoagulable state which most possibly was the reason of her previous miscarriages. This is the reason why she should be on aspirin and heparin in order to prevent any future miscarriage.

      Your Answer: Reassurance since she was asymptomatic and Staphylococcus saprophyticus sp is part of the normal human flora that colonizes the perineum & urethra

      Correct Answer: Prescribe her with Augmentin

      Explanation:

      In the given case, the patient should be treated with Augmentin.
      Asymptomatic bacteriuria occurs in about 2 % to 10 % of all pregnancies and if left untreated, about 30% of this will develop acute cystitis and the other 50% will develop acute pyelonephritis.

      Escherichia coli is the most common pathogen associated with asymptomatic bacteriuria, which consists more than 80% of the isolate and Staphylococcus Saprophyticus accounts for about 5-10% of isolates associated with uncomplicated UTI. Escherichia coli is a very common normal flora found in the gastrointestinal tract and Staphylococcus Saprophyticus is a commonly found normal flora in genital tract and perineum.

      Asymptomatic bacteriuria has found to be associated with low birth weight and preterm birth, and it is found that a short term antibiotic treatment will help in improving the fetal outcomes in cases of asymptomatic bacteriuria or uncomplicated UTI. Hence, all cases of asymptomatic bacteriuria and uncomplicated UTI during pregnancy are recommended to be treated with a five day course of oral antibiotics as this is normally sufficient in pregnant women.

      Drug of choice in asymptomatic bacteriuria (directed therapy based on sensitivities) in case of E. coli are either:
      – Cephalexin 500 mg oral twice a day for 5 days or
      – Nitrofurantoin 100 mg orally twice daily for 5 days or
      – Trimethoprim 300 mg oral doses daily for 5 days (avoided during first trimester and in those pregnant women with established folate deficiency, low dietary folate intake, or for women taking other folate antagonists).
      – Amoxicillin + clavulanate 500 + 125 mg oral, twice daily for 5 days if < 20 weeks of gestation.
      Note: In view of childhood outcomes – (ORACLE II trial and 7 year follow-up), which showed an associated increase in necrotising enterocolitis, functional impairment (low), and cerebral palsy, it is recommended that amoxicillin / clavulanate is only used if no alternative treatment is available(if >20 weeks of gestation).

      Asymptomatic bacteriuria (directed therapy based on sensitivities ) in case of Staphylococcus saprophyticus infection is as follows:
      Cephalexin 500 mg oral doses twice a day for 5 days or Amoxicillin 500mg TDS for 5 days.

      Asymptomatic bacteriuria (directed therapy based on sensitivities) in case of infection with Pseudomonas suggest Norfloxacin 400 mg oral twice daily for 5 days, then repeat MSSU 48 hours after the treatment is completed.

      In case of Group B streptococcus as a single organism, Penicillin V 500 mg oral twice daily for 5 days. If the patient is hypersensitive to penicillin give Cephalexin 500 mg orally twice a day for 5 days were immediate hypersensitivity is excluded. If immediate hypersensitivity to penicillin is noticed, then Clindamycin 450 mg three times daily for 5 days is advised.

      Amoxicillin is found more effective in treating UTIs caused by organisms which are resistant to the drug in vitro because of its high concentrations attainable in urine. However, a study shows that amoxicillin-resistant organisms do not respond to amoxicillin alone but Augmentin [amoxicillin clavulanate] is found to cure urinary tract infection irrespective of the amoxicillin susceptibility of the organism in vitro. Of the patients infected with amoxicillin-resistant organisms, 80% were cured by augmentin and only 10% with infection by amoxicillin-resistant organisms were cured by amoxicillin.

      Now a days Amoxicillin is not preferred as the common treatment option for UTI due to increasing incidences of Escherichia coli resistance, which accounts majority of uncomplicated urinary tract infections. Clavulanic acid which is a beta-lactamase inhibitor works synergistically with amoxicillin to extend spectrum antibiotic susceptibility. This makes UTIs less likely to be resistant to the treatment with amoxicillin clavulanate compared to amoxicillin alone.
      Ciprofloxacin and Gentamicin which are the other antibiotic choice considered otherwise also should be avoided in pregnancy as they comes under FDA pregnancy Category C.

    Incorrect

    • Among the below given options, which is NOT associated with an increased risk for preeclampsia?

      Your Answer: Nulliparity

      Correct Answer: Age between 18 and 40 years

      Explanation:

      Any new onset of hypertension associated with proteinuria after 20 weeks of gestation in a previously­ normotensive woman is referred to as Preeclampsia.
      Most commonly found risk factors for pre-eclampsia are:
      – Preeclampsia in a previous pregnancy
      – Family history of preeclampsia
      – a prior pregnancy with poor outcome like placental abruption, IUGR, fetal death in utero, etc
      – An interdelivery interval greater than 10 years
      – Nulliparity, increases risk by 8 times
      – Pre-existing chronic medical conditions or chronic hypertension
      – pre-existing or gestational Diabetes
      – chronic Renal disease
      – Thrombophilias g. protein C and S deficiency, antithrombin Ill deficiency, or Factor V Leiden mutation
      – Antiphospholipid syndrome
      – Systemic lupus erythematous
      – Maternal age greater than or equal to 40 years
      – Body Mass Index (BMI) greater than 30 kg/m2
      – Multiple pregnancy
      – Raised blood pressure at booking
      – Gestational trophoblastic disease
      – Fetal triploidy

      Maternal age between 18 and 40 years is found to be associated with a decreased risk for developing preeclampsia, and not an increased risk.
      NOTE– Previously, age 16 years or younger was thought to be a risk factor for developing preeclampsia; however, recent studies conducted had failed to establish any meaningful relationship between the two.

    Correct

    • The fetal head may undergo changes in shape during normal delivery. The most common aetiology listed is:

      Your Answer: Molding

      Explanation:

      With the help of molding, the fetal head changes its shape as the skull bones overlap. This helps in smooth delivery of the foetus through the birth canal.

    Incorrect

    • A 35-year-old woman presents to your gynaecologic clinic with complaints of abdominal bloating, headaches, insomnia, mood swings, and reduced sexual desire. These symptoms usually get worse a few days before the onset of menstruation and get better with menstruation.

      The most appropriate treatment strategy for such a patient is?

      Your Answer: Primrose oil

      Correct Answer: Sertraline

      Explanation:

      Premenstrual dysphoric disorder (PMDD) is a more serious form of premenstrual syndrome (PMS). PMS causes bloating, headaches, and breast tenderness a week or two before your period.

      With PMDD, you might have PMS symptoms along with extreme irritability, anxiety, or depression. These symptoms improve within a few days after your period starts, but they can be severe enough to interfere with your life.

      PMDD symptoms appear a week or two before menstruation and go away within a few days after your period starts. In addition to PMS symptoms, you may have:

      Anger or irritability.
      Anxiety and panic attacks.
      Depression and suicidal thoughts.
      Difficulty concentrating.
      Fatigue and low energy.
      Food cravings or binge eating.
      Headaches.
      Insomnia.
      Mood swings.

      The following treatments have been shown to relieve symptoms:

      Sertraline, escitalopram, paroxetine, and fluoxetine are SSRIs (selective serotonin reuptake inhibitors). SSRIs are the first-line treatment and are extremely effective.
      The second line of defence is alprazolam (a short course recommended due to its addictive potential).
      The use of temazepam has little advantage because it only aids with sleep and is relatively short-acting.
      Lifestyle modifications-weight loss, exercise, quitting smoking, and relaxation therapies for less severe PMS.
      Danazol-suppresses the ovulation and helps with mastalgias associated with PMS.

    Incorrect

    • A 56 year old lady presents with a vulval itch and discolouration. A biopsy conforms Lichen Sclerosis (LS). What is the risk of developing squamous cell carcinoma compared to patients with a normal vulval biopsy?

      Your Answer: <5%

      Correct Answer:

      Explanation:

      Lichen Sclerosis is a destructive inflammatory condition that effects the anogenital region of women. It effects around 1 in 300 women. It destroys the subdermal layers of the skin resulting in hyalinization of the skin leading to parchment paper appearance of the skin. It is associated with vulval cancer and it is estimated that the risk of developing vulval cancer after lichen sclerosis is around 3-5%.
