Giant pelvic retroperitoneal liposarcoma

Background: Pelvic retroperitoneal liposarcomas are rare in young women (un der 30 years old). We present a case of a giant well-differentiated liposar coma of the retroperitoneum in a young woman. Case: A 27-year-old nulligravida presented with rapid abdominal enlargement . Pelvic examination found a huge mass extending from the left adnexa to th e epigastric region. At surgery, the pelvic organs were displaced to the ri ght side by a retroperitoneal mass that marginally involved the left fallop ian tube. The left ovary, uterus, and right adnexa were not involved and we re not removed. No adjuvant irradiation was given. The patient was alive an d well 2 years after the operation and was 23 weeks pregnant. Conclusion: Gynecologists should be familiar with pelvic retroperitoneal li posarcomas and their treatment.
