Chapter 45: Disorders of the Female Reproductive System

Cervical disease forms a central focus, with the Bethesda system providing a standardized framework for categorizing squamous intraepithelial lesions into low-grade and high-grade variants, distinctions that directly correlate with specific human papillomavirus subtypes and prognostic implications. Current screening recommendations emphasize co-testing strategies combining HPV detection with cytological assessment in women aged thirty and beyond, reflecting evolving understanding of disease progression and risk stratification. High-grade cervical intraepithelial neoplasias are managed through loop electrosurgical excision procedures, which have become the preferred intervention over traditional cone biopsy due to improved safety profiles and comparable diagnostic accuracy. The chapter reconceptualizes abnormal uterine bleeding through a unified nomenclature system, organizing hemorrhage etiologies into structural and functional categories using the PALM-COEIN framework, which facilitates systematic diagnostic reasoning and therapeutic selection. Polycystic ovary syndrome emerges as a prevalent endocrine disorder characterized by reproductive dysfunction, metabolic disturbances, and clinical manifestations including hirsutism and anovulation, with diagnosis requiring integration of hormonal markers, glucose metabolism assessment, and imaging evaluation. Endometrial malignancy risk stratification incorporates metabolic and cardiovascular comorbidities, particularly obesity, hypertension, and diabetes mellitus as significant contributors to disease development. Breast cancer assessment incorporates sentinel lymph node biopsy methodology for nodal staging, a technique that enables accurate prognostic evaluation while reducing surgical morbidity compared to axillary dissection. Throughout the chapter, emphasis remains on understanding how classification systems and diagnostic algorithms inform clinical decision-making and treatment outcomes across these diverse reproductive pathologies.
