Abstract: Endometrial stromal sarcoma (ESS) is a rare malignant tumour of endometrium, occurring in age group of 40-50 years. We report a case of ESS in a 29-year-old woman with a clinical diagnosis of multiple leiomyoma. Total Laparoscopic hysterectomy was done under general anaesthesia. Histopathology and Immunohistochemistry helped to arrive at a final diagnosis of a low-grade Endometrial stromal sarcoma. As this tumour is rarely encountered, management protocols are questionable. Although rare, ESS should be considered in the differential diagnosis of a rapid enlargement of a uterine Leiomyoma. This case report is aimed at its rarity and difficulties faced in establishing the diagnosis.
