Purpose of Review <p>Adolescent endometriosis and chronic pelvic pain frequently overlap but represent distinct clinical entities requiring thoughtful diagnostic and management approach. This review summarizes recent advances in understanding adolescent endometriosis and its role in chronic pelvic pain, a condition frequently underrecognized and associated with significant diagnostic delay. We discuss emerging evidence regarding symptom patterns, mechanisms of pain, and treatment approaches.</p> Recent Findings <p>Increasing evidence supports a shift towards a noninvasive clinical diagnosis of endometriosis in adolescents rather than delaying treatment for surgical confirmation. Specialized imaging and biomarkers show promise for identifying later stage disease; they currently lack the sensitivity to definitively rule out endometriosis and are not yet validated in this population. Emerging data highlights the role of central sensitization and biopsychosocial factors in pain persistence, explaining why symptoms of endometriosis and chronic pelvic pain coexist and warrant multimodal management.</p> Summary <p>Chronic pelvic pain and endometriosis require comprehensive evaluation and management approaches that combine hormonal therapy, specialized surgery, and adjunctive treatments like pelvic floor physical therapy. Early intervention optimizes care and may mitigate long-term consequences on reproductive health and psychological well-being.</p>
