title: Retroperitoneal liposarcoma weighing over one hundred pounds with review of the literature.
abstract: BACKGROUND
  Rarely, excessively large, slow growing tumors are found to be malignant. One exception includes retroperitoneal tumors, which if considered a mass of pelvic origin, may be encountered by the gynecologic oncologist.
  
  
  METHODS
  A post-menopausal female was referred for evaluation of a huge mass thought to arise from the pelvis. The patient underwent exploratory laparotomy and had resected a 50x48x45 cm, 103.6 lb. liposarcoma arising from the right retroperitoneum.
  
  
  CONCLUSIONS
  Rarely, large slow growing abdomino-pelvic masses may be malignant, and one should be prepared to perform an appropriate surgical resection. This case represents removal of the largest retroperitoneal liposarcoma reported.
