Case Series of Incidental Findings of Low-Grade Endometrial Stromal Sarcoma on Routine Hysterectomy for Uterine Fibroids

This study is a retrospective review of data from patients who were incidentally diagnosed with endometrial stromal sarcoma after a routine hysterectomy for uterine fibroid at the Department of Gynaecologic Oncology in a tertiary care hospital. The Institutional Review Board (IRB) gave its clearance for this study before it was carried out. Informed written consent was obtained from all patients. In our case series, the three patients presented with complaints of menorrhagia, lower abdominal pain, intermenstrual bleeding, and acute retention of urine. After the patients underwent a clinical examination and radiological scan, the diagnosis of fibroids was made. They underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. Histology revealed low-grade endometrial stromal sarcoma (LGESS). The patients were observed for adjuvant therapy. The patients had a follow-up period of 18-24 months. In LGESS, which is rare, prompt management is of utmost importance, because the tumour's stage is the most significant predictor of the prognosis. As there are no clear indications to suggest the presence of LGESS prior to the histopathology of the specimen, it is necessary to analyze the data of patients who are diagnosed with LGESS, in order to investigate and manage the condition more appropriately. After myomectomy for a suspected leiomyoma, there is a 0.2% chance of the result showing endometrial stromal sarcoma.
