One-liner

This rapid review covers key board topics including breast pathology (Paget's disease, invasive lobulocarcinoma), PCOS management with spironolactone and OCPs, gynecologic cancer screening guidelines (endometrial biopsy necessity), testicular/ovarian germ cell tumor markers (-AFP, -hCG), molar pregnancy diagnosis, and common STI/UTI etiologies.

High-yield summary

• PCOS Management: For hyperandrogenism in PCOS, Spironolactone is the drug of choice because it inhibits 5-reductase activity in the skin. OCPs are used to regulate cycles when fertility is not desired.
• Endometrial Cancer Screening: Endometrial biopsy must be performed for any postmenopausal bleeding or significant risk factors for hyperestrogenism (e.g., PCOS, long-term HRT use), even if the patient is <50 years old.
• Molar Pregnancy: Classic presentation includes a uterus size greater than expected for gestational age (>BPD) in early pregnancy, often accompanied by high -hCG and a "snowstorm" appearance on ultrasound. Treatment requires suction curettage.
• Breast Cancer Pathology: A biopsy showing central clearing and an e-cat hearing mutation strongly suggests invasive lobulocarcinoma; treatment involves Trastuzumab (anti-HER2).
• STI Diagnosis: Mucopurulent discharge points to Neisseria gonorrhoeae; watery/non-gonococcal urethritis requires testing for Chlamydia trachomatis, which does not stain well with Gram stain.
• BPH Management: Acute symptoms are managed with _1-blockers (e.g., Tamsulosin), but long-term shrinkage requires 5-reductase inhibitors (Finasteride/Dutasteride).

Learning objectives

• Differentiate the clinical presentation and management of various breast pathologies (e.g., fibroadenoma vs Paget's disease).
• Apply knowledge of PCOS pathophysiology, including hyperandrogenism mechanisms and appropriate hormonal/anti-androgenic treatments.
• Recognize the critical role of tumor markers (\alpha-AFP, \beta-hCG) in diagnosing ovarian and testicular germ cell tumors.
• Understand the screening guidelines for endometrial carcinoma based on risk factors (PCOS, HRT).
• Identify key drug interactions and contraindications related to reproductive health (e.g., OCPs, vasodilators).
