BACKGROUND Epithelial neoplasms are the most common and heterogenous group of ovarian tumors. Approximately 10-15% are primary ovarian mucinous neoplasms. Almost 80% of these consist of benign mucinous neoplasms, while the rest are borderline neoplasms, non-invasive (intraepithelial and intraglandular) carcinomas, and invasive carcinomas. Small ovarian cystadenomas are generally asymptomatic and are mainly found incidentally during an ultrasound examination for another gynecologic disorder. As their size increases, nonspecific symptoms and clinical signs develop as a result of mass effect to adjacent structures or because of tumor torsion. The main clinical symptoms are abdominal and/or pelvic pain, fullness, and discomfort. Large cystadenomas have also been associated with nausea and vomiting, urinary problems, persistent cough, back pain, metrorrhagia, and feminization. CASE REPORT We report a case of a 31-year-old woman with a body mass index of 39 who presented with increasing sacrococcygeal pain and right leg paresthesia over a 2-year period. She was treated for possible musculoskeletal and spine problems. She was finally diagnosed with a large right ovarian mucinous cystadenoma expanding in the sacrococcygeal region. She was successfully treated with complete excision of the tumor and achieved complete remission of all her symptoms. CONCLUSIONS Large ovarian mucinous cystadenomas, which develop in the sacrococcygeal region, can lead to symptoms that mimic musculoskeletal and spine problems. Early diagnosis is of great importance towards the goal of implementing proper therapeutic approaches and achieve complete remission of all clinical symptoms.
