- What is the most appropriate next step in the management of this patient?
Answer: Perform a vulvar punch biopsy of the ulcerated lesion
Any suspicious vulvar lesion, especially in an elderly woman with chronic symptoms, must be biopsied to rule out malignancy. The presentation is concerning for vulvar squamous cell carcinoma, which is the most common type of vulvar cancer. While the white plaques may represent co-existing lichen sclerosus (a risk factor), the ulcerated lesion requires a tissue diagnosis. Treating empirically with corticosteroids or antifungals would delay a potential cancer diagnosis. Herpes would typically present with vesicles and is less likely to be a chronic, solitary ulcer.
- Postmenopausal bleeding; biopsy grade 1 endometrioid cancer. Initial treatment?
Answer: Complete surgical staging
Grade 1 endometrioid cancer is still invasive endometrial cancer, so initial management is complete surgical staging with hysterectomy, bilateral salpingo-oophorectomy, and lymph node evaluation. Progestin therapy alone is the tempting option, but it is reserved for atypical hyperplasia or selected patients who want fertility preservation and cannot have surgery; it is not standard initial treatment for documented cancer.
- What is the most appropriate next step in management?
Answer: Repeat co-testing in 1 year
According to current guidelines, for a woman aged 30 or older with a negative Pap test but a positive high-risk HPV test, the preferred management is to repeat co-testing in one year. This approach is based on the high likelihood that the HPV infection will clear spontaneously. If the repeat testing shows ASC-US or greater, or if the HPV test remains positive, colposcopy would then be recommended. Immediate colposcopy is not recommended for this specific combination of results, as it would lead to over-investigation. Resuming routine screening would be inappropriate given the positive HPV result.
- Which of the following is the most appropriate contraceptive to initiate at this time?
Answer: Progestin-only pill
Progestin-only contraceptives, such as the progestin-only pill, are the preferred hormonal method for breastfeeding women. They do not contain estrogen and have not been shown to adversely affect milk production, quality, or infant growth. Estrogen-containing methods (combined pill, patch, ring) are generally avoided in the immediate postpartum period (first 4-6 weeks) due to an increased risk of venous thromboembolism and potential negative effects on lactation.
- BMI 34, unprotected sex 72h ago. Most effective emergency contraception?
Answer: Copper intrauterine device
The copper IUD is the most effective emergency contraception, works up to 120 hours after unprotected sex, and its efficacy is not reduced by obesity. With BMI 34, oral options are less reliable, so the IUD is preferred. Ulipristal acetate is the best oral choice but is still less effective than the IUD and loses potency at higher BMI.
- What is the most appropriate initial step in the evaluation of this couple's infertility?
Answer: Semen analysis
The initial evaluation of an infertile couple should include an assessment of ovulatory function, tubal and uterine anatomy, and male factors. Semen analysis is a simple, noninvasive, and cost-effective test that can identify male factor infertility, which accounts for up to 50% of cases. Given its high yield and low risk, it is a crucial first step. Hysterosalpingogram is more invasive and is typically performed after semen analysis. A mid-luteal phase progesterone level assesses ovulation, which is likely normal given the patient's regular cycles. Clomiphene citrate is a treatment, and therapy should not be initiated before a diagnosis is established.
- According to current screening guidelines, what is the most appropriate next step in management?
Answer: Reflex human papillomavirus (HPV) testing
The preferred management for a Papanicolaou (Pap) test result of ASC-US in a woman aged 25 or older is reflex HPV testing from the same sample. If the HPV test is positive, the patient should be referred for colposcopy. If the HPV test is negative, she can return to routine screening. Repeating the Pap smear in one year is an alternative if HPV testing is not available or was not performed. Immediate colposcopy is indicated for higher-grade lesions (e.g., HSIL) or if the ASC-US result is positive for high-risk HPV. LEEP is a treatment modality, not an initial diagnostic step for ASC-US.
- Which of the following contraceptive methods would be most suitable for her needs?
Answer: Levonorgestrel-releasing IUD
The levonorgestrel-releasing IUD (LNG-IUD) is an excellent choice for this patient. It is a long-acting reversible contraceptive (LARC), making it highly effective and eliminating the need for daily adherence. A significant non-contraceptive benefit of the LNG-IUD is a reduction in menstrual bleeding and dysmenorrhea, which would directly address her complaint of heavy, painful periods. The copper IUD is also a LARC but is known to potentially increase menstrual bleeding and cramping. Fertility awareness methods are less effective. The progestin-only pill requires strict daily adherence.
- 25yo, ASC-US cytology, high-risk HPV negative. Next step?
Answer: Routine cytology in 3 years
An HPV-negative ASC-US result carries low risk, equivalent to a normal co-test, so you can return to routine screening in 3 years. The tempting wrong answer is repeat cytology in 1 year, but that applies to HPV-positive or unknown HPV status; with negative high-risk HPV, neither colposcopy nor early repeat is needed.
- A 24-year-old wants long-term contraception. She has migraine with aura and is taking topiramate. No smoking. BP 116/74. Pregnancy test negative. She wants the most effective method with minimal user action. Which contraceptive method is most suitable for this patient?
Answer: Etonogestrel implant
This question tests knowledge in reproductive endocrinology, contraception, and gynecologic oncology, specifically focusing on contraception in patients with migraine with aura. Understanding the nuances in choosing appropriate diagnostic and management strategies is crucial in patient care. In this scenario, the migraine with aura and desire for low-maintenance method guide the most appropriate clinical decision. The correct choice, etonogestrel implant, aligns with US MEC guidelines and directly addresses the need for a progestin-only, long-acting option. A common mistake is selecting combined oral contraceptive pill, which fails because estrogen is contraindicated in migraine with aura. Teaching strategies include reviewing current guidelines on contraceptive safety, understanding the indications and contraindications of various treatments, and practicing with similar clinical scenarios to reinforce learning.
- A 45-year-old presents with postmenopausal bleeding. She is 6 years postmenopause. History: type 2 diabetes and obesity. Meds: metformin. Exam: normal cervix, small uterus. Transvaginal ultrasound shows endometrial thickness 3 mm and no adnexal mass. CBC normal. What is the most appropriate management for this patient's condition?
Answer: Reassurance and outpatient follow-up if bleeding resolves
This question tests knowledge in reproductive endocrinology, contraception, and gynecologic oncology, specifically focusing on management of postmenopausal bleeding with thin endometrium. Understanding the nuances in choosing appropriate diagnostic and management strategies is crucial in patient care. In this scenario, the endometrial thickness of 3 mm on ultrasound guides the most appropriate clinical decision. The correct choice, reassurance and outpatient follow-up if bleeding resolves, aligns with ACOG guidelines and directly addresses the low risk of malignancy. A common mistake is selecting endometrial biopsy, which fails because biopsy is not indicated when thickness is below 4 mm in asymptomatic cases. Teaching strategies include reviewing current guidelines on endometrial evaluation, understanding the indications and contraindications of various treatments, and practicing with similar clinical scenarios to reinforce learning.
- What is the most appropriate initial recommendation to improve her fertility?
Answer: Weight loss through diet and exercise
For overweight and obese women with PCOS, weight loss is the first-line intervention for improving fertility. Even a modest weight loss of 5-10% of total body weight can restore spontaneous ovulation, improve response to fertility medications, and lead to better pregnancy outcomes. While pharmacologic agents like letrozole are effective for ovulation induction, they are most effective when combined with lifestyle modifications. IVF and diagnostic laparoscopy are not initial steps in management.
- A 32-year-old G0 has irregular menses and infertility. She is a competitive runner with 10-lb weight loss, stress fracture history, and low libido. Meds: none. Exam: BMI 18, bradycardia. Labs: urine hCG negative, FSH low, LH low, estradiol low, prolactin normal, TSH normal. Pelvic ultrasound shows thin endometrium. What is the most likely diagnosis based on the clinical findings?
Answer: Functional hypothalamic amenorrhea
This question tests knowledge in reproductive endocrinology, contraception, and gynecologic oncology, specifically focusing on diagnosis of amenorrhea in underweight athletes. Understanding the nuances in choosing appropriate diagnostic and management strategies is crucial in patient care. In this scenario, the low BMI, exercise history, and low gonadotropins guide the most appropriate clinical decision. The correct choice, functional hypothalamic amenorrhea, aligns with Endocrine Society guidelines and directly addresses the energy deficiency etiology. A common mistake is selecting polycystic ovary syndrome, which fails because it typically presents with hyperandrogenism and normal/high gonadotropins. Teaching strategies include reviewing current guidelines on amenorrhea classification, understanding the indications and contraindications of various treatments, and practicing with similar clinical scenarios to reinforce learning.
- A 32-year-old G0 presents with infertility and irregular cycles. She reports milky nipple discharge and headaches. Meds: none. Exam: galactorrhea present; visual fields normal. Tests: urine hCG negative, prolactin 85 ng/mL, TSH normal, FSH/LH low-normal. Pelvic ultrasound normal. Which diagnostic test is most indicated given the patient's symptoms?
Answer: MRI of the pituitary with contrast
This question tests knowledge in reproductive endocrinology, contraception, and gynecologic oncology, specifically focusing on evaluation of hyperprolactinemia in infertility. Understanding the nuances in choosing appropriate diagnostic and management strategies is crucial in patient care. In this scenario, the elevated prolactin, galactorrhea, and headaches guide the most appropriate clinical decision. The correct choice, MRI of the pituitary with contrast, aligns with Endocrine Society guidelines and directly addresses the suspicion for pituitary adenoma. A common mistake is selecting serum CA-125 level, which fails because it is irrelevant to hyperprolactinemia without ovarian pathology. Teaching strategies include reviewing current guidelines on prolactin disorders, understanding the indications and contraindications of various treatments, and practicing with similar clinical scenarios to reinforce learning.
- Which of the following contraceptive methods is contraindicated in this patient?
Answer: Combined oral contraceptive pills
Combined hormonal contraceptives (containing both estrogen and progestin) are contraindicated in women with migraine with aura due to an increased risk of ischemic stroke. The estrogen component is believed to be responsible for this risk. Progestin-only methods, such as the progestin-only pill and the levonorgestrel-releasing IUD, as well as non-hormonal methods like the copper IUD, are safe and appropriate alternatives for this patient.
- 28yo with 4 months amenorrhea; progestin withdrawal bleeding occurs. Most likely diagnosis?
Answer: Polycystic ovary syndrome
Withdrawal bleeding after progestin means your endometrium has been primed by estrogen, so the problem is anovulation, not estrogen deficiency or outflow obstruction. In a young woman, PCOS is the most common cause of chronic anovulatory amenorrhea. Hypothalamic amenorrhea is the tempting wrong answer, but it causes low estrogen, so progestin typically produces no withdrawal bleed.
- What is the most appropriate next step in management?
Answer: Switch to an OCP with a higher estrogen dose
Breakthrough bleeding is a common side effect of OCPs, particularly in the first 3 months. Since her symptoms have persisted beyond 3 months, management should be considered. This bleeding is often due to insufficient estrogen to stabilize the endometrium. The most appropriate step is to switch to a formulation with a higher estrogen dose (e.g., from 20 mcg to 30 or 35 mcg ethinyl estradiol) to provide better endometrial support. An endometrial biopsy is not indicated in this young, low-risk patient. Discontinuing OCPs is an option, but adjusting the formulation first may resolve the issue. Simple reassurance is less appropriate now that the issue has persisted for several months.
- What is the most appropriate first-line pharmacologic agent to induce ovulation in this patient?
Answer: Letrozole
Letrozole, an aromatase inhibitor, is the recommended first-line agent for ovulation induction in women with PCOS. It has been shown to have higher rates of live birth compared to clomiphene citrate, which was previously first-line. Metformin can improve metabolic parameters and may be used as an adjunct but is less effective than letrozole as a primary ovulation agent. Human menopausal gonadotropins are injectable medications that are considered second-line due to their higher cost, need for intensive monitoring, and increased risk of multiple gestation and ovarian hyperstimulation syndrome. Leuprolide is a GnRH agonist and is not used for this purpose.
- A 45-year-old with postmenopausal bleeding has an endometrial biopsy showing endometrioid adenocarcinoma. Ultrasound earlier noted a 6-cm complex right adnexal mass. History: obesity. Meds: none. Exam: mobile uterus, right adnexal fullness. What is the most appropriate management for this patient's condition?
Answer: Total hysterectomy with bilateral salpingo-oophorectomy and surgical staging
This question tests knowledge in reproductive endocrinology, contraception, and gynecologic oncology, specifically focusing on surgical management of endometrial cancer with adnexal involvement. Understanding the nuances in choosing appropriate diagnostic and management strategies is crucial in patient care. In this scenario, the biopsy-proven endometrioid adenocarcinoma and complex adnexal mass guide the most appropriate clinical decision. The correct choice, total hysterectomy with bilateral salpingo-oophorectomy and surgical staging, aligns with NCCN guidelines and directly addresses comprehensive oncologic treatment. A common mistake is selecting observation with repeat biopsy, which fails because it delays definitive therapy in confirmed malignancy. Teaching strategies include reviewing current guidelines on endometrial cancer staging, understanding the indications and contraindications of various treatments, and practicing with similar clinical scenarios to reinforce learning.
- 28yo with premature ovarian insufficiency. Best long-term therapy?
Answer: Hormone therapy until age 51
Premature ovarian insufficiency means estrogen deficiency before the usual age of menopause, so hormone therapy until about age 51 replaces that loss and protects bone and cardiovascular health. The tempting wrong answer is combined oral contraceptive; it contains estrogen but is not the preferred long-term replacement for POI. Calcium/vitamin D or bisphosphonates alone fail to treat the underlying estrogen deficiency.
