Kidney sparing giant retroperitoneal liposarcoma: Case report and literature review.

Introduction: Liposarcoma is the most common variant of soft tissue sarcoma. It often originates in retroperitoneum or perirenal fat. Early diagnosis is extremely difficult due to its location in the retroperitoneum that allows for room for growth.

A Case of Retroperitoneal Metastases That Occur 14 Years After Surgery.

Endometrial Stromal Sarcomas are rare malignant tumours of the uterus. We report the case of incidental finding of Low-Grade Endometrial Stromal Sarcoma (LGESS) that metastasized to the retroperitoneum 14 years after the original surgery in a 72-year-old woman. The patient underwent a laparotomy and excision of all tumour nodules.
