Navigating the Diagnostic Labyrinth: A Narrative Review of Atypical Pelvic Pain Syndromes at the Intersection of Gynecologic Oncology, Chronic Infection, and Odontogenic Referred Pain

Background: Atypical pelvic pain presents a profound diagnostic challenge, often masking serious underlying pathology across disparate anatomical systems. The convergence of gynecologic malignancies, chronic pelvic inflammatory disease (PID), and referred pain from advanced odontogenic infections creates a clinical triad requiring sophisticated multidisciplinary differentiation. Aim: This narrative review synthesizes current evidence to construct an integrated diagnostic pathway for atypical pelvic pain, emphasizing the collaborative roles of gynecologic oncology, infectious diseases, internal medicine, dentistry, radiology, laboratory medicine, nursing, and administrative support. Methods: A comprehensive search of PubMed, Scopus, CINAHL, and Cochrane databases was conducted for English-language articles published between 2010 and 2024. Search terms included "pelvic pain differential diagnosis," "gynecologic cancer masquerade," "chronic pelvic inflammatory disease," "odontogenic referred pain," "multidisciplinary pain assessment," combined with specific disciplines. Results: The review delineates distinct yet overlapping clinical presentations, biomarker profiles, and imaging findings for ovarian/endometrial malignancies, chronic PID, and maxillofacial pain referral. Key discriminators include nuanced symptom patterns (cyclic vs. constant, positional relationships), inflammatory markers (CA-125, CRP, PVL), and cross-sectional imaging characteristics. Conclusion: Atypical pelvic pain demands a paradigm shift from sequential specialty consultation to synchronous, coordinated multidisciplinary evaluation. Implementing structured diagnostic algorithms with clear referral triggers can reduce time-to-diagnosis, optimize resource use, and improve patient outcomes. Future directions include developing integrated clinics and shared decision-support tools.
