Paratubal Borderline Malignancy: A Case of a 17-Year-Old Adolescent Female Treated with Laparo-Endoscopic Single-Site Surgery and a Review of the Literature

Background: Although paratubal cysts are common, borderline paratubal cysts are extremely rare. We describe the case of a large borderline paratubal cyst in a 17-year-old adolescent female treated with laparo-endoscopic single-site surgery (LESS), and review the literature. Case: A 17-year-old female was referred due to a large right adnexal cyst on pelvic sonogram. A CT scan showed a 19-cm cystic lesion with enhancing papillary projection along the wall. Laparo-endoscopic single-site surgery confirmed a large cystic mass that originated from the right salpinx. Right salpingectomy and right ovarian wedge resection were performed, and intraoperative frozen section analysis was conducted. The result of the frozen section analysis and final pathologic review indicated that the cyst was a serous papillary-type borderline tumor in a paratubal cyst. Summary and Conclusion: To the best of our knowledge, this is the first case report of a BPC treated with LESS. We suggest that minimally invasive, fertility-preserving surgery should be considered as a standard treatment of borderline paratubal cysts if patients desire future fertility.
