Two cases of large retroperitoneal schwannoma treated with minimally invasive surgery. Role of the gynecologic oncologist

Background. Schwannomas are neurogenic tumors originating in the Schwann cells of the nerve sheath. Methods. This paper describes two consecutive cases of retroperitoneal pelvic schwannomas and review the current understanding and management in this unusual location by a team of gynecologist oncologists. Results. Minimally invasive surgical removal of retroperitoneal schwannomas is feasible, surgeons and patients must be aware of the possible early and long term collaterals. Conclusion. Gynecologist oncologists are the professional figure who is perhaps best placed for removing lumps from the retroperitoneal space because of familiarity with the structures involved in the dissection. We describe the challenges involved in preoperative diagnosis and minimally invasive management.
