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. Considering the common recurrence of and slow growing nature of LGESS, appropriate treatment options like surgical excision and life-long follow up should be considered.
