Background:
Pelvic retroperitoneal liposarcomas are rare tumors of mesenchymal origin. We present a case of a giant pelvic well-differentiated liposarcoma of the retroperitoneum in a woman, presenting with a large abdominal mass.
Case:
A 62-year-old woman presented with a rapid abdominal enlargement. Pelvic examination revealed a huge mass occupying the whole pelvis and part of the right abdomen. At surgery, the pelvic organs were displaced to the right side by a retroperitoneal mass that marginally involved the part of the posterior abdominal wall, left parietal peritoneum of the diaphragm, left colic flexure and the left adnexa. The huge mass, uterus, and both adnexa were removed; hemicolectomy and latero-lateral anastomosis were carried out. No adjuvant irradiation was given. The patient is alive and free of disease five years after the operation.
Conclusion:
The gynecologist should consider retroperitoneal liposarcoma in the differential diagnosis of large pelvic or abdominal masses.
