Retroperitoneal sarcomas obstructing delivery: two case reports.
Two patients with abnormal fetal lies underwent elective Caesarean section. Both abnormal lies were found to be due to retroperitoneal sarcomas overlying the bifurcation of the iliac vessels. One proved to be an inoperable and radioresistant fibrosarcoma. At seven and a half years after Caesarean section and following chemotherapy this patient is alive and well and has had two more children. The other tumour was a large myxoid liposarcoma which was completely removed at the time of Caesarean section. This patient is alive and well 18 months after operation.
