Secondary cytoreduction with intraperitoneal chemotherapy is feasible in most women with recurrent ovarian cancer with acceptable morbidity and mortality. Complete cytoreduction is not possible if distant and unresectable metastases are present or if the small bowel is extensively seeded. Long-term survivors are patients with limited peritoneal dissemination who may undergo complete cytoreduction.

SummaryBackground:Retroperitoneal schwannomas are very rare and are usually found incidentally.Cases Report:Two rare cases of retroperitoneal schwannomas are reported. Both were incidentally found during US scans for non-specific epigastric pain and were initially diagnosed as non-secreting retroperitoneal tumors. The diagnosis was confirmed by CT scan. In both patients the tumors were resected. The definitive diagnosis was possible by histopathology.Conclusions:Although the preoperative assessment of a retroperitoneal tumor may be indicative of a retroperitoneal schwannoma, the definitive diagnosis is possible only by histopathology after surgical removal of the tumor.
