Giant pelvic retroperitoneal liposarcoma.

BACKGROUND

Pelvic retroperitoneal liposarcomas are rare in young women (under 30 years old). We present a case of a giant well-differentiated liposarcoma 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 the epigastric region. At surgery, the pelvic organs were displaced to the right side by a retroperitoneal mass that marginally involved the left fallopian tube. The left ovary, uterus, and right adnexa were not involved and were not removed. No adjuvant irradiation was given. The patient was alive and well 2 years after the operation and was 23 weeks pregnant.

CONCLUSION

Gynecologists should be familiar with pelvic retroperitoneal liposarcomas and their treatment.
